causing a conventional spreading of the RF energy about the frequency
carrier. The frequency of the carrier is not fixed but changes at fixed
intervals under the direction of a coded sequence. The wide RF bandwidth
needed by such a system is not required by spreading of the RF energy
about the carrier but rather to accommodate the range of frequencies to
which the carrier frequency can hop. The test of a frequency hopping
system is that the near term distribution of hops appears random, the
long term distribution appears evenly distributed over the hop set, and
sequential hops are randomly distributed in both direction and magnitude
of change in the hop set.

direction, the same field strength or the same power flux-density at the
same distance. When not specified otherwise, the gain refers to the
direction of maximum radiation. The gain may be considered for a
specified polarization.
Note: Depending on the choice of the reference antenna a distinction
is made between:
(1) Absolute or isotropic gain (Gi), when the reference antenna is
an isotropic antenna isolated in space;
(2) Gain relative to a half-wave dipole (Gd), when the reference
antenna is a half-wave
[[Page 453]]
dipole isolated in space whose equatorial plane contains the given
direction;
(3) Gain relative to a short vertical antenna (Gv), when the
reference antenna is a linear conductor, much shorter than one quarter
of the wavelength, normal to the surface of a perfectly conducting plane
which contains the given direction. (RR)

Sec. 2.102 Assignment of frequencies.
(a) Except as otherwise provided in this section, the assignment of
frequencies and bands of frequencies to all stations and classes of
stations and the licensing and authorizing of the use of all such
frequencies between 9 kHz and 400 GHz, and the actual use of such
frequencies for radio communication or for any other purpose, including
the transfer of energy by radio, shall be in accordance with the Table
of Frequency Allocations in Sec. 2.106.
(b) On the condition that harmful interference will not be caused to
services operating in accordance with the Table of Frequency Allocations
the following exceptions to paragraph (a) of this section may be
authorized:
(1) In individual cases the Commission may, without rule making
proceedings, authorize on a temporary basis only, the use of frequencies
not in accordance with the Table of Frequency Allocations for projects
of short duration or emergencies where the Commission finds that
important or exceptional circumstances require such utilization. Such
authorizations are not intended to develop a service to be operated on
frequencies other than those allocated such service.
(2) A station for the development of techniques or equipment to be
employed by services set forth in column 5 of the Table of Frequency
Allocations may be authorized the use of frequencies allocated to those
services or classes of stations.
(3) Experimental stations pursuant to part 5, may be authorized the
use of any frequency or frequency band not exclusively allocated to the
passive services (including the Radio Astronomy Service).
(4) In the event a band is reallocated so as to delete its
availability for use by a particular service, the Commission may provide
for the further interim use of the band by stations in that service for
a temporary, specific period of time.
[[Page 461]]
(c) Non-Government stations may be authorized to use Government
frequencies in the bands above 25 MHz if the Commission finds, after

(1) Non-Government operation on Government frequencies shall conform
with the conditions agreed upon by the Commission and the National
Telecommunications and Information Administration (NTIA) (the more
important of which are contained in paragraphs (c) (2), (3), and (4) of
this section);
(2) Such operations shall be in accordance with NTIA rules governing
the service to which the frequencies involved are allocated;
(3) Such operations shall not cause harmful interference to
Government stations and, should harmful interference result, that the

Government agency involved and this certification has been furnished, in
writing, to the non-Government licensee with which communication is
required.
(d) Aircraft stations may communicate with stations of the maritime
mobile service. They shall then conform to those provisions of the
international Radio Regulations which relate to the maritime mobile
service. For this purpose aircraft stations should use the frequencies
allocated to the maritime mobile service. However, having regard to
interference which may be caused by aircraft stations at high altitudes,
maritime mobile frequencies in the bands above 30 MHz shall not be used
by aircraft stations in any specific area without the prior agreement of
all administrations of the area in which interference is likely to be
caused. In particular, aircraft stations operating in Region 1 should
not use frequencies in the bands above 30 MHz allocated to the maritime
mobile service by virtue of any agreement between administrations in
that Region.
(e) Non-Government services operating on frequencies in the band 25-
50 MHz must recognize that it is shared with various services of other
countries; that harmful interference may be caused by skywave signals
received from distant stations of all services of the United States and
other countries radiating power on frequencies in this band; and that no
protection from such harmful interference generally can be expected.
Persons desiring to avoid such harmful interference should consider
operation on available frequencies higher in the radio spectrum not
generally subject to this type of difficulty.
(f) The stations of a service shall use frequencies so separated
from the limits of a band allocated to that service as not to cause
harmful interference to allocated services in immediately adjoining

(2) That harmful interference will not be caused to services
operating in accordance with the Table of Frequency Allocations.
(h) Special provisions regarding the use of spectrum allocated to
the fixed and land mobile services below 25 MHz by non-Government
stations.

insular areas, the Commission does not intend to seek international
protection for assignments made pursuant to paragraphs (h) (1)(ii) and
(2) of this section; this results in the following constraints upon the
circuits/assignments.
(i) The Commission will not accept responsibility for protection of
the circuits from harmful interference caused by foreign operations.
(ii) In the event that a complaint of harmful interference resulting
from operation of these circuits is received from a foreign source, the
offending circuit(s) must cease operation on the particular frequency
concerned.
(iii) In order to accommodate the situations described in paragraphs
(h)(3) (i) and (ii) of this section, equipments shall be capable of
transmitting and receiving on any frequency in the bands assigned to the
particular operation and capable of immediate change among the
frequencies.

(a) Government stations may be authorized to use non-Government
frequencies in the bands above 25 MHz (except the 764-776 MHz and 794-
806 MHz public safety bands) if the Commission finds that such use is
necessary for coordination of Government and non-Government activities:
Provided, however, that:
(1) Government operation on non-Government frequencies shall conform
with the conditions agreed upon by the Commission and the National
Telecommunications and Information Administration (the more important of
which are contained in paragraphs (a)(2), (a)(3) and (a)(4) of this
section);
(2) Such operations shall be in accordance with Commission rules
governing the service to which the frequencies involved are allocated;

Government entities if the Commission finds such use necessary; where:
(1) The stations are used for interoperability or part of a
Government/non-Government shared or joint-use system;
(2) The Government entity obtains the approval of the non-Government
(State/local government) licensee(s) or applicant(s) involved;
(3) Government operation is in accordance with the Commission's
Rules governing operation of this band and conforms with any conditions
agreed
[[Page 463]]
upon by the Commission and the National Telecommunications and
Information Administration; and
(4) Interoperability, shared or joint-use systems are the subject of
a mutual agreement between the Government and non-Government entities.
This section does not preclude other arrangements or agreements as
permitted under part 90 of the rules. See 47 CFR 90.179 and 90.421 of
this chapter.

(4) The lines A, B and C are defined as follows:
(i) Line A. Line A extends from the North Pole along meridian
40[deg] East of Greenwich to parallel 40[deg] North; thence by great
circle arc to the intersection of meridian 60[deg] East and the Tropic
of Cancer; thence along the meridian 60[deg] East to the South Pole.
(ii) Line B. Line B extends from the North Pole along meridian
10[deg] West of Greenwich to its intersection with parallel 72[deg]
North; thence by great circle arc to the intersection of meridian
50[deg] West and parallel 40[deg] North; thence by great circle arc to
the intersection of meridian 20[deg] West and parallel 10[deg] South;
thence along meridian 20[deg] West to the South Pole.
(iii) Line C. Line C extends from the North Pole by great circle arc
to the intersection of parallel 65[deg]30[min] North with the
international boundary in Bering Strait; thence by great circle arc to
the intersection of meridian 165[deg] East of Greenwich and parallel
50[deg] North; thence by great circle arc to the intersection of
meridian 170[deg] West and parallel 10[deg] North; thence along parallel
10[deg] North to its intersection with meridian 120[deg] West; thence
along meridian 120[deg] West to the South Pole.
(c) Areas. To further assist in the international allocation of the
radio spectrum, the ITU has established five special geographical areas
and they are defined as follows:
(1) The term ``African Broadcasting Area'' means:
(i) African countries, parts of countries, territories and groups of
territories situated between the parallels 40[deg] South and 30[deg]
North;
(ii) Islands in the Indian Ocean west of meridian 60[deg] East of
Greenwich, situated between the parallel 40[deg] South and the great
circle arc joining the points 45[deg] East, 11[deg]30[min] North and
60[deg] East, 15[deg] North; and
(iii) Islands in the Atlantic Ocean east of line B, situated between
the parallels 40[deg] South and 30[deg] North.
(2) The ``European Broadcasting Area'' is bounded on the west by the
[[Page 464]]
western boundary of Region 1, on the east by the meridian 40[deg] East
of Greenwich and on the south by the parallel 30[deg] North so as to
include the northern part of Saudi Arabia and that part of those
countries bordering the Mediterranean within these limits. In addition,
Iraq, Jordan and that part of the territory of Syria, Turkey and Ukraine
lying outside the above limits are included in the European Broadcasting
Area.
(3) The ``European Maritime Area'' is bounded to the north by a line
extending along parallel 72[deg] North from its intersection with
meridian 55[deg] East of Greenwich to its intersection with meridian
5[deg] West, then along meridian 5[deg] West to its intersection with
parallel 67[deg] North, thence along parallel 67[deg] North to its
intersection with meridian 32[deg] West; to the west by a line extending
along meridian 32[deg] West to its intersection with parallel 30[deg]
North; to the south by a line extending along parallel 30[deg] North to
its intersection with meridian 43[deg] East; to the east by a line
extending along meridian 43[deg] East to its intersection with parallel
60[deg] North, thence along parallel 60[deg] North to its intersection
with meridian 55[deg] East and thence along meridian 55[deg] East to its
intersection with parallel 72[deg] North.
(4) The ``Tropical Zone'' (see Figure 1 of this section) is defined
as:
(i) The whole of that area in Region 2 between the Tropics of Cancer
and Capricorn.
(ii) The whole of that area in Regions 1 and 3 contained between the
parallels 30[deg] North and 35[deg] South with the addition of:
(A) The area contained between the meridians 40[deg] East and
80[deg] East of Greenwich and the parallels 30[deg] North and 40[deg]
North; and
(B) That part of Libya north of parallel 30[deg] North.
(iii) In Region 2, the Tropical Zone may be extended to parallel
33[deg] North, subject to special agreements between the countries
concerned in that Region.
(5) A sub-Region is an area consisting of two or more countries in
the same Region.
(d) Categories of services and allocations. (1) Primary and
secondary services. Where, in a box of the International Table in Sec.
2.106, a band is indicated as allocated to more than one service, either
on a worldwide or Regional basis, such services are listed in the
following order:
(i) Services the names of which are printed in ``capitals''
(example: FIXED); these are called ``primary'' services; and
(ii) Services the names of which are printed in ``normal
characters'' (example: Mobile); these are called ``secondary'' services
(see paragraph (d)(3) of this section).
(2) Additional remarks shall be printed in normal characters
(example: MOBILE except aeronautical mobile).
(3) Stations of a secondary service:
(i) Shall not cause harmful interference to stations of primary
services to which frequencies are already assigned or to which
frequencies may be assigned at a later date;
(ii) Cannot claim protection from harmful interference from stations
of a primary service to which frequencies are already assigned or may be
assigned at a later date; and
(iii) Can claim protection, however, from harmful interference from
stations of the same or other secondary service(s) to which frequencies
may be assigned at a later date.
(4) Where a band is indicated in a footnote of the International
Table as allocated to a service ``on a secondary basis'' in an area
smaller than a Region, or in a particular country, this is a secondary
service (see paragraph (d)(3) of this section).
(5) Where a band is indicated in a footnote of the International
Table as allocated to a service ``on a primary basis'', in an area
smaller than a Region, or in a particular country, this is a primary
service only in that area or country.
(e) Additional allocations. (1) Where a band is indicated in a
footnote of the International Table as ``also allocated'' to a service
in an area smaller than a Region, or in a particular country, this is an
``additional'' allocation, i.e. an allocation which is added in this
area or in this country to the service or services which are indicated
in the International Table.
[[Page 465]]
(2) If the footnote does not include any restriction on the service
or services concerned apart from the restriction to operate only in a
particular area or country, stations of this service or these services
shall have equality of right to operate with stations of the other
primary service or services indicated in the International Table.
(3) If restrictions are imposed on an additional allocation in
addition to the restriction to operate only in a particular area or
country, this is indicated in the footnote of the International Table.
(f) Alternative allocations. (1) Where a band is indicated in a
footnote of the International Table as ``allocated'' to one or more
services in an area smaller than a Region, or in a particular country,
this is an ``alternative'' allocation, i.e. an allocation which
replaces, in this area or in this country, the allocation indicated in
the Table.
(2) If the footnote does not include any restriction on stations of
the service or services concerned, apart from the restriction to operate
only in a particular area or country, these stations of such a service
or services shall have an equality of right to operate with stations of
the primary service or services, indicated in the International Table,
to which the band is allocated in other areas or countries.
(3) If restrictions are imposed on stations of a service to which an
alternative allocation is made, in addition to the restriction to
operate only in a particular country or area, this is indicated in the
footnote.
(g) Miscellaneous provisions. (1) Where it is indicated that a
service may operate in a specific frequency band subject to not causing
harmful interference, this means also that this service cannot claim
protection from harmful interference caused by other services to which
the band is allocated under Chapter SII of the international Radio
Regulations.
(2) Except if otherwise specified in a footnote, the term ``fixed
service'', where appearing in the International Table, does not include
systems using ionospheric scatter propagation.
(h) Description of the International Table of Frequency Allocations.
(1) The heading of the International Table includes three columns, each
of which corresponds to one of the Regions (see paragraph (b) of this
section). Where an allocation occupies the whole of the width of the
Table or only one or two of the three columns, this is a worldwide
allocation or a Regional allocation, respectively.
(2) The frequency band referred to in each allocation is indicated
in the left-hand top corner of the part of the Table concerned.
(3) Within each of the categories specified in paragraph (d)(1) of
this section, services are listed in alphabetical order according to the
French language. The order of listing does not indicate relative
priority within each category.
(4) In the case where there is a parenthetical addition to an
allocation in the International Table, that service allocation is
restricted to the type of operation so indicated.
(5) The footnote references which appear in the International Table
below the allocated service or services apply to the whole of the
allocation concerned.
(6) The footnote references which appear to the right of the name of
a service are applicable only to that particular service.
(7) In certain cases, the names of countries appearing in the
footnotes have been simplified in order to shorten the text.

Sec. 2.105 United States Table of Frequency Allocations.
(a) The United States Table of Frequency Allocations (United States
Table) is subdivided into the Federal Government Table of Frequency
Allocations (Federal Government Table, column 4 of Sec. 2.106) and the
Non-Federal Government Table of Frequency Allocations (Non-Federal
Government Table, column 5 of Sec. 2.106). The United States Table is
based on the Region 2 Table because the relevant area of jurisdiction is
located primarily in Region 2 \1\ (i.e., the 50 States, the District of
Columbia, the Caribbean insular areas \2\ and some of the Pacific
insular areas).\3\ \4\ The Federal Government Table is administered by
the National Telecommunications and Information Administration (NTIA)
\5\, whereas the Non-Federal Government Table is administered by the
Federal Communications Commission (FCC).\6\
---------------------------------------------------------------------------
\1\ See Sec. 2.104(a)(1) for definition of Region 2.
\2\ The Caribbean insular areas are: The Commonwealth of Puerto
Rico; the unincorporated territory of the United States Virgin Islands;
and Navassa Island.
\3\ The Pacific insular areas located in Region 2 are: Johnston
Atoll and Midway Atoll.
\4\ The operation of stations in the Pacific insular areas located
in Region 3 are generally governed by the International plan for Region
3 (i.e., column 3 of Sec. 2.106). The Pacific insular areas located in
Region 3 are: the Commonwealth of the Northern Mariana Islands; the
unincorporated territory of American Samoa; the unincorporated territory
of Guam; and Baker Island, Howland Island, Jarvis Island, Kingman Reef,
Palmyra Island and Wake Island.
\5\ Section 305(a) of the Communications Act of 1934, as amended.
See Pub. Law 102-538, 106 Stat. 3533 (1992).
\6\ The Communications Act of 1934, as amended.
---------------------------------------------------------------------------
(b) In the United States, radio spectrum may be allocated to either
Federal government or non-Federal government use exclusively, or for
shared use. In the case of shared use, the type of service(s) permitted
need not be the same [e.g., Federal government FIXED, non-Federal
government MOBILE]. The terms used to designate categories of services
and allocations \7\ in columns 4 and 5 of Sec. 2.106 correspond to the
terms employed by the International Telecommunication Union (ITU) in the
international Radio Regulations.
---------------------------------------------------------------------------
\7\ Definitions of the various radio services used are contained in
Sec. 2.1.
---------------------------------------------------------------------------
(c) Category of services. (1) Any segment of the radio spectrum may
be allocated to the Federal government and/or non-Federal government
sectors either on an exclusive or shared basis for use by one or more
radio services. In the case where an allocation has been made to more
than one service, such services are listed in the following order:
(i) Services, the names of which are printed in ``capitals''
[example: FIXED]; these are called ``primary'' services;
(ii) Services, the names of which are printed in ``normal
characters'' [example: Mobile]; these are called ``secondary'' services.
(2) Stations of a secondary service:
(i) Shall not cause harmful interference to stations of primary
services to which frequencies are already assigned or to which
frequencies may be assigned at a later date;
(ii) Cannot claim protection from harmful interference from stations
of a primary service to which frequencies are already assigned or may be
assigned at a later date; and
(iii) Can claim protection, however, from harmful interference from
stations of the same or other secondary service(s) to which frequencies
may be assigned at a later date.
(d) Format of the United States Table and the Rule Part Cross
Reference Column. (1) The frequency band referred to in each allocation,
column 4 for Federal government and column 5 for non-Federal government,
is indicated in the left-hand top corner of the column. If there is no
service or footnote indicated for a band of frequencies in either column
4 or 5, then the Federal government or the non-Federal government
sector, respectively, has no access to that band except as provided for
by Sec. 2.102.
(2) When the Federal Government and Non-Federal Government Tables
are exactly the same for a shared band, the line between columns 4 and 5
is deleted and the allocations are shown once.
(3) The Federal Government Table, given in column 4, is included for
informational purposes only.
[[Page 468]]
(4) In the case where there is a parenthetical addition to an
allocation in the United States Table [example: FIXED-SATELLITE (space-
to-earth)], that service allocation is restricted to the type of
operation so indicated.
(5) The following symbols are used to designate footnotes in the
United States Table:
(i) Any footnote consisting of ``S5.'' followed by one or more
digits, e.g., S5.53, or any footnote not prefixed by a letter, e.g.,
459, denotes an international footnote. Where an international footnote
is applicable, without modification, to the United States Table, the
footnote appears in the United States Table (columns 4 and 5) and
denotes a stipulation affecting both the Federal Government Table and
the Non-Federal Government Table. If, however, an international footnote
pertains to a service allocated only for Federal government or non-
Federal government use, the international footnote will be placed only
in the affected Table. For example, ``AMATEUR S5.142'' shall be shown
only in the Non-Federal Government Table.
(ii) Any footnote consisting of the letters US followed by one or
more digits, e.g., US7, denotes a stipulation affecting both the Federal
Government Table and the Non-Federal Government Table.
(iii) Any footnote consisting of the letters NG followed by one or
more digits, e.g., NG2, denotes a stipulation applicable only to the
Non-Federal Government Table (column 5).
(iv) Any footnote consisting of the letter G following by one or
more digits, e.g., G2, denotes a stipulation applicable only to the
Federal Government Table (column 4).
(6) If a frequency or frequency band has been allocated to a
radiocommunication service in the Non-Federal Government Table, then a
cross reference may be added for the pertinent FCC Rule part (column 6
of Sec. 2.106). For example, the 849-851 MHz band is allocated to the
non-Federal government aeronautical mobile service, rules for the use of
the 849-851 MHz band have been added to Part 22--Public Mobile Services
(47 CFR part 22), and a cross reference, Public Mobile (22), has been
added in Column 6 of the Table. The exact use that can be made of any
given frequency or frequency band (e.g., channelling plans, allowable
emissions, etc.) is given in the FCC Rule part(s) so indicated. The FCC
Rule parts in this column are not allocations and are provided for
informational purposes only. This column also may contain explanatory
notes for informational purposes only.

International Footnotes
5.53 Administrations authorizing the use of frequencies below 9 kHz
shall ensure that no harmful interference is caused thereby to the
services to which the bands above 9 kHz are allocated.
5.54 Administrations conducting scientific research using
frequencies below 9
[[Page 558]]
kHz are urged to advise other administrations that may be concerned in
order that such research may be afforded all practicable protection from
harmful interference.
5.55 Additional allocation: in Armenia, Azerbaijan, Bulgaria,
Georgia, Kyrgyzstan, the Russian Federation, Tajikistan and
Turkmenistan, the band 14-17 kHz is also allocated to the
radionavigation service on a primary basis.
5.56 The stations of services to which the bands 14-19.95 kHz and
20.05-70 kHz and in Region 1 also the bands 72-84 kHz and 86-90 kHz are
allocated may transmit standard frequency and time signals. Such
stations shall be afforded protection from harmful interference. In
Armenia, Azerbaijan, Belarus, Bulgaria, Georgia, Kazakstan, Mongolia,
Uzbekistan, Kyrgyzstan, Slovakia, the Czech Rep., Russian Federation,
Tajikistan, Turkmenistan and Ukraine, the frequencies 25 kHz and 50 kHz
will be used for this purpose under the same conditions.
5.57 The use of the bands 14-19.95 kHz, 20.05-70 kHz and 70-90 kHz
(72-84 kHz and 86-90 kHz in Region 1) by the maritime mobile service is
limited to coast radiotelegraph stations (A1A and F1B only).
Exceptionally, the use of class J2B or J7B emissions is authorized
subject to the necessary bandwidth not exceeding that normally used for
class A1A or F1B emissions in the band concerned.
5.58 Additional allocation: in Armenia, Azerbaijan, Georgia,
Kazakstan, Kyrgyzstan, the Russian Federation, Tajikistan and
Turkmenistan, the band 67-70 kHz is also allocated to the
radionavigation service on a primary basis.
5.59 Different category of service: in Bangladesh and Pakistan, the
allocation of the bands 70-72 kHz and 84-86 kHz to the fixed and
maritime mobile services is on a primary basis (see No. 5.33).
5.60 In the bands 70-90 kHz (70-86 kHz in Region 1) and 110-130 kHz
(112-130 kHz in Region 1), pulsed radionavigation systems may be used on
condition that they do not cause harmful interference to other services
to which these bands are allocated.
5.61 In Region 2, the establishment and operation of stations in the
maritime radionavigation service in the bands 70-90 kHz and 110-130 kHz
shall be subject to agreement obtained under No. 9.21 with
administrations whose services, operating in accordance with the Table,
may be affected. However, stations of the fixed, maritime mobile and
radiolocation services shall not cause harmful interference to stations
in the maritime radionavigation service established under such
agreements.
5.62 Administrations which operate stations in the radionavigation
service in the band 90-110 kHz are urged to coordinate technical and
operating characteristics in such a way as to avoid harmful interference
to the services provided by these stations.
5.64 Only classes A1A or F1B, A2C, A3C, F1C or F3C emissions are
authorized for stations of the fixed service in the bands allocated to
this service between 90 kHz and 160 kHz (148.5 kHz in Region 1) and for
stations of the maritime mobile service in the bands allocated to this
service between 110 kHz and 160 kHz (148.5 kHz in Region 1).
Exceptionally, class J2B or J7B emissions are also authorized in the
bands between 110 kHz and 160 kHz (148.5 kHz in Region 1) for stations
of the maritime mobile service.
5.65 Different category of service: in Bangladesh, the allocation of
the bands 112-117.6 kHz and 126-129 kHz to the fixed and maritime mobile
services is on a primary basis (see No. 5.33).
5.66 Different category of service: in Germany, the allocation of
the band 115-117.6 kHz to the fixed and maritime mobile services is on a
primary basis (see No. 5.33) and to the radionavigation service on a
secondary basis (see No. 5.32).
5.67 Additional allocation: in Azerbaijan, Bulgaria, Mongolia,

components thereof on a secondary basis to the Wireless Communications
Service. The following two frequencies are shared on a co-equal basis by
Government and non-Government stations for telemetering and associated
telecommand operations of expendable and re-usable launch vehicles
whether or not such operations involve flight testing: 2312.5 and 2352.5
MHz. Other mobile telemetering uses may be provided on a non-
interference basis to the above uses. The broadcasting-satellite (sound)
service during implementation should also take cognizance of the
expendable and reusable launch vehicle frequencies 2312.5 and 2352.5
MHz, to minimize the impact on this mobile service use to the extent
possible.
US340 The band 2-30 MHz is available on a non-interference basis to
Federal and non-Federal Government maritime and aeronautical stations
for the purposes of measuring the quality of reception on radio
channels. See 47 CFR 87.149 for the list of protected frequencies and
bands within this frequency range. Actual communications shall be
limited to those frequencies specifically allocated to the maritime
mobile and aeronautical mobile services.

are allocated, all practicable steps shall be taken to protect the radio
astronomy service from harmful interference. Emissions from spaceborne
or airborne stations can be particularly serious sources of interference
to the radio astronomy service (see Nos. 4.5 and 4.6 and Article 29 of
the ITU Radio Regulations).
US343 Differential-Global-Positioning-System (DGPS) Stations,
limited to ground-based transmitters, may be authorized on a primary
basis in the bands 108-117.975 and 1559-1610 MHz for the specific
purpose of transmitting DGPS information intended for aircraft
navigation. Such use shall be in accordance with ITU Resolution 413
(WRC-03).
[[Page 609]]
US344 In the band 5091-5250 MHz, non-Government earth stations in
the fixed-satellite service (Earth-to-space) shall be coordinated
through the Frequency Assignment Subcommittee (see Recommendation ITU-R
S.1342). In order to better protect the operation of the international
standard system (microwave landing system) in the band 5000-5091 MHz,
non-Government tracking and telecommand operations should be conducted
in the band 5150-5250 MHz.
US345 In the band 402-405 MHz, the mobile, except mobile
aeronautical, service is allocated on a secondary basis and is limited
to, with the exception of military tactical mobile stations, Medical
Implant Communications Service (MICS) operations. MICS stations are
authorized by rule on the condition that harmful interference is not
caused to stations in the meteorological aids, meteorological-satellite,
and earth exploration-satellite services, and that MICS stations accept
interference from stations in the meteorological aids, meteorological-
satellite, and earth exploration-satellite services.
US346 Except as provided by footnote US222, the use of the band
2025-2110 MHz by the Government space operation service (Earth-to-
space), Earth exploration-satellite service (Earth-to-space), and space
research service (Earth-to-space) shall not constrain the deployment of
the Television Broadcast Auxiliary Service, the Cable Television Relay
Service, or the Local Television Transmission Service. To facilitate
compatible operations between non-Government terrestrial receiving
stations at fixed sites and Government earth station transmitters,
coordination is required. To facilitate compatible operations between
non-government terrestrial transmitting stations and Government
spacecraft receivers, the terrestrial transmitters shall not be high-
density systems (see Recommendations ITU-R SA.1154 and ITU-R F.1247).
US347 In the band 2025-2110 MHz, non-Government Earth-to-space and
space-to-space transmissions may be authorized in the space research and
Earth exploration-satellite services subject to such conditions as may
be applied on a case-by-case basis. Such transmissions shall not cause
harmful interference to Government and non-Government stations operating
in accordance with the Table of Frequency Allocations.
US348 The band 3650-3700 MHz is also allocated to the Government
radiolocation service on a primary basis at the following sites: St.
Inigoes, MD (38[deg]10[min] N., 76[deg]23[min] W.); Pascagoula, MS

space research service for which information for advance publication has
been received by the ITU Radiocommunication Bureau (Bureau) prior to 31
January 1992 shall operate on an equal basis with stations in the fixed-
satellite service; after that date, new geostationary space stations in
the space research service will operate on a secondary basis. Until
those geostationary space stations in the space research service for
which information for advance publication has been received by the
Bureau prior to 31 January 1992 cease to operate in this band:
a. The e.i.r.p. density of emissions from any earth station in the
fixed-satellite service operating with a space station in geostationary-
satellite orbit shall not exceed 71 dBW in any 6 MHz band from 13.77 to
13.78 GHz;
b. The e.i.r.p. density of emissions from any earth station in the
fixed-satellite service operating with a space station in non-
geostationary-satellite orbit shall not exceed 51 dBW in any 6 MHz band
from 13.77 to 13.78 GHz.
Automatic power control may be used to increase the e.i.r.p. density
in any 6 MHz band in these frequency ranges to compensate for rain
attenuation, to the extent that the power flux-density at the fixed-
satellite service space station does not exceed the value resulting from
use by an earth station of an e.i.r.p. of 71 dBW or 51 dBW, as
appropriate, in any 6 MHz band in clear-sky conditions.
US359 In the band 15.43-15.63 GHz, use of the fixed-satellite
service (Earth-to-space) is limited to non-Government feeder links of
non-geostationary systems in the mobile-satellite service. These non-

(a) Pursuant to No. 1492 of Article 13 and Section F of Appendix 3
to the
[[Page 623]]
international Radio Regulations (Geneva, 1982), operators of radio
astronomy stations desiring international recognition of their use of
specific radio astronomy frequencies or bands of frequencies for
reception, should file the following information with the Commission for
inclusion in the Master International Frequency Register:
(1) The center of the frequency band observed, in kilohertz up to
28,000 kHz inclusive, in megahertz above 28,000 kHz to 10,500 MHz
inclusive and in gigahertz above 10,500 MHz.
(2) The date (actual or foreseen, as appropriate) when reception of
the frequency band begins.
(3) The name and location of the station, including geographical
coordinates in degrees and minutes.
(4) The width of the frequency band (in kHz) observed by the
station.
(5) The antenna type and dimensions, effective area and angular
coverage in azimuth and elevation.
(6) The regular hours of reception (in UTC) of the observed
frequency.
(7) The overall receiving system noise temperature (in kelvins)
referred to the output of the receiving antenna.
(8) The class of observations to be taken. Class A observations are
those in which the sensitivity of the equipment is not a primary factor.
Class B observations are those of such a nature that they can be made
only with advanced low-noise receivers using the best techniques.
(9) The name and mailing address of the operator.
(b) The permanent discontinuance of observations, or any change to
the information above, should also be filed with the Commission.
(c) Observations being conducted on frequencies or frequency bands
not allocated to the radio astronomy service should be reported as in
paragraph (a) of this section for information purposes. Information in
this category will not be submitted for entry in the Master
International Frequency Register and protection from interference will
not be afforded such operations by stations in other services.
Sec. 2.108 Policy regarding the use of the fixed-satellite allocations
in the 3.6-3.7, 4.5-4.8, and 5.85-5.925 GHz bands.
The use of the fixed-satellite allocations in the United States in
the above bands will be governed by footnote US245. Use of the fixed-
satellite service allocations in these bands is for the international
fixed-satellite service, that is, for international inter-continental
communications. Case-by-case electromagnetic compatibility analysis is
required with all users of the bands. It is anticipated that one earth
station on each coast can be successfully coordinated. Specific
locations of these earth stations depend upon service requirements and
case-by-case EMC analyses that demonstrate compatible operations.
Subpart C_Emissions
Sec. 2.201 Emission, modulation, and transmission characteristics.
The following system of designating emission, modulation, and
transmission characteristics shall be employed.
(a) Emissions are designated according to their classification and
their necessary bandwidth.
(b) A minimum of three symbols are used to describe the basic
characteristics of radio waves. Emissions are classified and symbolized
according to the following characteristics:
(1) First symbol--type of modulation of the main character;
(2) Second symbol--nature of signal(s) modulating the main carrier;
(3) Third symbol--type of information to be transmitted.
Note: A fourth and fifth symbol are provided for additional
information and are shown in Appendix 6, part A of the ITU Radio
Regulations. Use of the fourth and fifth symbol is optional. Therefore,

symbol for that emission, as given above, shall be preceded by the
necessary bandwidth of the emission as indicated in Sec. 2.202(b)(1).
[49 FR 48697, Dec. 14, 1984]
[[Page 625]]
Sec. 2.202 Bandwidths.
(a) Occupied bandwidth. The frequency bandwidth such that, below its
lower and above its upper frequency limits, the mean powers radiated are
each equal to 0.5 percent of the total mean power radiated by a given
emission. In some cases, for example multichannel frequency-division
systems, the percentage of 0.5 percent may lead to certain difficulties
in the practical application of the definitions of occupied and
necessary bandwidth; in such cases a different percentage may prove
useful.
(b) Necessary bandwidth. For a given class of emission, the minimum
value of the occupied bandwidth sufficient to ensure the transmission of
information at the rate and with the quality required for the system
employed, under specified conditions. Emissions useful for the good
functioning of the receiving equipment as, for example, the emission
corresponding to the carrier of reduced carrier systems, shall be
included in the necessary bandwidth.
(1) The necessary bandwidth shall be expressed by three numerals and
one letter. The letter occupies the position of the decimal point and
represents the unit of bandwidth. The first character shall be neither
zero nor K, M or G.
(2) Necessary bandwidths:
between 0.001 and 999 Hz shall be expressed in Hz (letter H);
between 1.00 and 999 kHz shall be expressed in kHz (letter K);
between 1.00 and 999 MHz shall be expressed in MHz (letter M);
between 1.00 and 999 GHz shall be expressed in GHz (letter G).
(3) Examples:
0.002 Hz--H002
0.1 Hz--H100
25.3 Hz--25H3
400 Hz--400H
2.4 kHz--2K40
6 kHz--6K00
12.5 kHz--12K5
180.4 kHz--180K
180.5 kHz--181K
180.7 kHz--181K
1.25 MHz--1M25
2 MHz--2M00
10 MHz--10M0
202 MHz--202M
5.65 GHz--5G65
(c) The necessary bandwidth may be determined by one of the
following methods:
(1) Use of the formulas included in the table, in paragraph (g) of
this section, which also gives examples of necessary bandwidths and
designation of corresponding emissions;
(2) For frequency modulated radio systems which have a substantially
linear relationship between the value of input voltage to the modulator
and the resulting frequency deviation of the carrier and which carry
either single sideband suppressed carrier frequency division multiplex
speech channels or television, computation in accordance with provisions
of paragraph (f) of this section and formulas and methods indicated in
the table, in paragraph (g) of this section;
(3) Computation in accordance with Recommendations of the
International Radio Consultative Committee (C.C.I.R.);
(4) Measurement in cases not covered by paragraph (c) (1), (2), or
(3) of this section.
(d) The value so determined should be used when the full designation
of an emission is required. However, the necessary bandwidth so
determined is not the only characteristic of an emission to be
considered in evaluating the interference that may be caused by that
emission.
(e) In the formulation of the table in paragraph (g) of this
section, the following terms are employed:
Bn = Necessary bandwidth in hertz
B = Modulation rate in bauds
N = Maximum possible number of black plus white elements to be
transmitted per second, in facsimile
M = Maximum modulation frequency in hertz
C = Sub-carrier frequency in hertz
D = Peak frequency deviation, i.e., half the difference between the
maximum and minimum values of the instantaneous frequency. The
instantaneous frequency in hertz is the time rate of change in phase in
radians divided by 2
t = Pulse duration in seconds at half-amplitude
tr = Pulse rise time in seconds between 10% and 90% of
maximum amplitude
K = An overall numerical factor which varies according to the emission
and which depends upon the allowable signal distortion.
Nc = Number of baseband telephone channels in radio systems
employing multichannel multiplexing
P = Continuity pilot sub-carrier frequency (Hz) (continuous signal
utilized to verify performance of frequency-division multiplex systems).
[[Page 626]]
(f) Determination of values of D and Bn for systems
specified in paragraph (c)(2) of this section:
(1) Determination of D in systems for multichannel telephony:
(i) The rms value of the per-channel deviation for the system shall
be specified. (In the case of systems employing preemphasis or phase
modulation, this value of per-channel deviation shall be specified at
the characteristic baseband frequency.)
(ii) The value of D is then calculated by multiplying the rms value
of the per-channel deviation by the appropriate factors, as follows:
----------------------------------------------------------------------------------------------------------------
Number of message circuits Multiplying factors Limits of X (Pavg (dBmO))
----------------------------------------------------------------------------------------------------------------
More than 3, but less than 12.......... 4.47 x [a factor specified by the
equipment manufacturer or station
licensee, subject to Commission
approval].
3.76 antilog (X+2 log10 Nc)
At least 12, but less than 60.......... -------------------------- X: -2 to +2.6.
20
3.76 antilog (X+4 log10 Nc)
At least 60, but less than 240......... -------------------------- X: -5.6 to -1.0.
20
3.76 antilog (X+10 log10 Nc)
240 or more............................ -------------------------- X: -19.6 to -15.0.
20
----------------------------------------------------------------------------------------------------------------
Where X represents the average power in a message circuit in dBmO; Nc is the number of circuits in the
multiplexed message load; 3.76 corresponds to a peak load factor of 11.5 dB.
(2) The necessary bandwidth (Bn) normally is considered
to be numerically equal to:
(i) 2M+2DK, for systems having no continuity pilot subcarrier or
having a continuity pilot subcarrier whose frequency is not the highest
modulating the main carrier;
(ii) 2P+2DK, for systems having a continuity pilot subcarrier whose
frequency exceeds that of any other signal modulating the main carrier,
unless the conditions set forth in paragraph (f)(3) of this section are
met.
(3) As an exception to paragraph (f)(2)(ii) of this section, the
necessary bandwidth (Bn) for such systems is numerically
equal to 2P or 2M+2DK, whichever is greater, provided the following
conditions are met:
(i) The modulation index of the main carrier due to the continuity
pilot subcarrier does not exceed 0.25, and
(ii) In a radio system of multichannel telephony, the rms frequency
deviation of the main carrier due to the continuity pilot subcarrier
does not exceed 70 percent of the rms value of the per-channel
deviation, or, in a radio system for television, the rms deviation of
the main carrier due to the pilot does not exceed 3.55 percent of the
peak deviation of the main carrier.

Sec. 2.924 Marketing of electrically identical equipment having multiple
trade names and models or type numbers under the same FCC Identifier.
The grantee of an equipment authorization may market devices having
different model/type numbers or trade names without additional
authorization from the Commission, provided that such devices are
electrically identical and the equipment bears an FCC Identifier
validated by a grant of equipment authorization. A device will be
considered to be electrically identical if no changes are made to the
device authorized by the Commission, or if the changes made to the
device would be treated as class I permissive changes within the scope
of Sec. 2.1043(b)(1). Changes to the model number or trade name by
anyone other than the grantee, or under the authorization of the
grantee, shall be performed following the procedures in Sec. 2.933.
[62 FR 10470, Mar. 7, 1997, as amended at 63 FR 36598, July 7, 1998]
Sec. 2.925 Identification of equipment.
(a) Each equipment covered in an application for equipment
authorization shall bear a nameplate or label listing the following:
(1) FCC Identifier consisting of the two elements in the exact order
specified in Sec. 2.926. The FCC Identifier shall be preceded by the
term FCC ID in capital letters on a single line, and shall be of a type
size large enough to be legible without the aid of magnification.
Example: FCC ID XXX123. XXX--Grantee Code 123--Equipment Product
Code
(2) Any other statements or labeling requirements imposed by the
rules governing the operation of the specific class of equipment, except
that such statement(s) of compliance may appear on a separate label at
the option of the applicant/grantee.
(3) Equipment subject only to registration will be identified
pursuant to part 68 of this chapter.
(b) Any device subject to more than one equipment authorization
procedure may be assigned a single FCC Identifier. However, a single FCC
Identifier is required to be assigned to any device consisting of two or
more sections assembled in a common enclosure, on a common chassis or
circuit board, and with common frequency controlling circuits. Devices
to which a single FCC Identifier has been assigned shall be identified
pursuant to paragraph (a) of this section.
(1) Separate FCC Identifiers may be assigned to a device consisting
of two or more sections assembled in a common enclosure, but constructed
on separate sub-units or circuit boards with independent frequency
controlling circuits. The FCC Identifier assigned to any transmitter
section shall be preceded by the term TX FCC ID, the FCC Identifier
assigned to any receiver section shall be preceded by the term RX FCC ID
and the identifier assigned to any remaining section(s) shall be
preceded by the term FCC ID.
(2) Where telephone equipment subject to part 68 of this chapter,
and a radiofrequency device subject to equipment authorization
requirements are assembled in a common enclosure, the nameplate/label
shall display the FCC Registration Number in the format specified in
part 68 and the FCC Identifier in the format specified in paragraph (a)
of this section.
[[Page 643]]
(3) Applications filed on or after May 1, 1981, and applications
filed earlier requesting equipment authorization using the single system
of identification pursuant to section (a)(1) will receive a review of
the identification portion by the Commission's Laboratory with respect
to nameplate/label design within 30 days after receipt at the
Laboratory. Failure by the Laboratory to reject a nameplate design
proposed in any particular application within this time period will
constitute de-facto acceptance of the nameplate/label design for that
particular equipment. Such de facto acceptance will be limited to the
equipment covered by the particular application and will not be
considered to establish a precedent for other applications. This review
deadline applies only to the proposed nameplate/label design, not to the
remainder of the application.
(4) For a transceiver, the receiver portion of which is subject to
verification pursuant to Sec. 15.101 of this chapter, the FCC
Identifier required for the transmitter portion shall be preceded by the
term FCC ID.
(c) [Reserved]
(d) In order to validate the grant of equipment authorization, the
nameplate or label shall be permanently affixed to the equipment and
shall be readily visible to the purchaser at the time of purchase.
(1) As used here, permanently affixed means that the required
nameplate data is etched, engraved, stamped, indelibly printed, or
otherwise permanently marked on a permanently attached part of the
equipment enclosure. Alternatively, the required information may be
permanently marked on a nameplate of metal, plastic, or other material
fastened to the equipment enclosure by welding, riveting, etc., or with
a permanent adhesive. Such a nameplate must be able to last the expected
lifetime of the equipment in the environment in which the equipment will
be operated and must not be readily detachable.
(2) As used here, readily visible means that the nameplate or
nameplate data must be visible from the outside of the equipment
enclosure. It is preferable that it be visible at all times during
normal installation or use, but this is not a prerequisite for grant of
equipment authorization.
(e) A software defined radio may be equipped with a means such as a
user display screen to display the FCC identification number normally
contained in the nameplate or label. The information must be readily
accessible, and the user manual must describe how to access the
electronic display.
(f) Where it is shown that a permanently affixed nameplate is not
desirable or is not feasible, an alternative method of positively
identifying the equipment may be used if approved by the Commission. The
proposed alternative method of identification and the justification for
its use must be included with the application for equipment
authorization.
Note: As an example, a device intended to be implanted within the
body of a test animal or person would probably require an alternate
method of identification.
(g) The term FCC ID and the coded identification assigned by the
Commission shall be in a size of type large enough to be readily
legible, consistent with the dimensions of the equipment and its
nameplate. However, the type size for the FCC Identifier is not required
to be larger than eight-point.

Sec. 2.926 FCC identifier.
(a) A grant of equipment authorization issued by the Commission will
list the validated FCC Identifier consisting of the grantee code
assigned by the FCC pursuant to paragraph (b) of this section, and the
equipment product code assigned by the grantee pursuant to paragraph (c)
of this section. See Sec. 2.925.
(b) The grantee code assigned pursuant to paragraph (c) of this
section is assigned permanently to applicants/grantees and is valid only
for the party specified as the applicant/grantee in the code
assignment(s).
(c) A grantee code will have three characters consisting of Arabic
numerals, capital letters, or combination thereof. A prospective grantee
or his authorized representative may submit
[[Page 644]]
a written request to the Commission for assignment of a grantee code at
any time. However, it is preferred that grantee codes be requested prior
to filing applications for equipment authorization. If a grantee code is
not requested in advance, one will be assigned at the time an
application is received by the FCC Laboratory and the applicant will be
notified to make any necessary label revisions in order to comply fully
with application procedural rules.
(1) After assignment of a grantee code each grantee will continue to
use the same grantee code for subsequent equipment authorization
applications.
In the event the grantee name is changed or ownership is
transferred, the circumstances shall be reported to the Commission so
that a new grantee code can be assigned, if appropriate. See Sec. Sec.
2.934 and 2.935 for additional information.
(2) [Reserved]
(d) The equipment product code assigned by the grantee shall consist
of a series of Arabic numerals, capital letters or a combination
thereof, and may include the dash or hyphen (-). The total of Arabic
numerals, capital letters and dashes or hyphens shall not exceed 14 and
shall be one which has not been previously used in conjunction with:
(1) The same grantee code, or
(2) An application denied pursuant to Sec. 2.919 of this chapter.
(e) No FCC Identifier may be used on equipment to be marketed unless
that specific identifier has been validated by a grant of equipment
authorization issued by the Commission. This shall not prohibit
placement of an FCC identifier on a transceiver which includes a
verified receiver subject to Sec. 15.101, provided that the transmitter
portion of such transceiver is covered by a valid grant of type
acceptance or certification. The FCC Identifier is uniquely assigned to
the grantee and may not be placed on the equipment without authorization
by the grantee. See Sec. 2.803 for conditions applicable to the display
at trade shows of equipment which has not been granted equipment
authorization where such grant is required prior to marketing. Labelling
of such equipment may include model or type numbers, but shall not
include a purported FCC Identifier.

Sec. 2.951 Cross reference.
The provisions of Sec. 2.901, et seq., shall apply to equipment
subject to verification.
Sec. 2.952 Limitation on verification.
(a) Verification signifies that the manufacturer or importer has
determined that the equipment has been shown to be capable of compliance
with the applicable technical standards if no unauthorized change is
made in the equipment and if the equipment is properly maintained and
operated. Compliance with these standards shall not be construed to be a
finding by the manufacturer or importer with respect to matters not
encompassed by the Commission's rules.
(b) Verification of the equipment by the manufacturer or importer is
effective until a termination date is otherwise established by the
Commission.
(c) No person shall, in any advertising matter, brochure, etc., use
or make reference to a verification in a deceptive or misleading manner
or convey the impression that such verification reflects more than a
determination by the manufacturer or importer that the device or product
has been shown to be capable of compliance with the applicable technical
standards of the Commission's rules.
Sec. 2.953 Responsibility for compliance.
(a) In verifying compliance, the responsible party, as defined in
Sec. 2.909 warrants that each unit of equipment marketed under the
verification procedure will be identical to the unit tested and found
acceptable with the standards and that the records maintained by the
responsible party continue to reflect the equipment being produced under
such verification within the variation that can be expected due to
quantity production and testing on a statistical basis.
(b) The importer of equipment subject to verification may upon
receiving a written statement from the manufacturer that the equipment
complies with the appropriate technical standards rely on the
manufacturer or independent testing agency to verify compliance. The
test records required by Sec. 2.955 however should be in the English
language and made available to the Commission upon a reasonable request,
in accordance with Sec. 2.956.
(c) In the case of transfer of control of equipment, as in the case
of sale or merger of the grantee, the new manufacturer or importer shall
bear the responsibility of continued compliance of the equipment.
(d) Verified equipment shall be reverified if any modification or
change adversely affects the emanation characteristics of the modified
equipment. The party designated in Sec. 2.909 bears responsibility for
continued compliance of subsequently produced equipment.

Sec. 2.960 Designation of Telecommunication Certification Bodies (TCBs).
(a) The Commission may designate Telecommunication Certification
Bodies (TCBs) to approve equipment as required under this part.
Certification of equipment by a TCB shall be based on an application
with all the information specified in this part. The TCB shall process
the application to determine whether the product meets the Commission's
requirements and shall issue a written grant of equipment authorization.
The grant shall identify the TCB and the source of authority for issuing
it.
(b) The Federal Communications Commission shall designate TCBs in
the United States to approve equipment subject to certification under
the Commission's rules. TCBs shall be accredited by the National
Institute of Standards and Technology (NIST) under its National
Voluntary Conformity Assessment Evaluation (NVCASE) program, or other
recognized programs based on ISO/IEC Guide 65, to comply with the
Commission's qualification criteria for TCBs. NIST may, in accordance
with its procedures, allow other appropriately qualified accrediting
bodies to accredit TCBs and testing laboratories. TCBs shall comply with
the requirements in Sec. 2.962 of this part.
(c) In accordance with the terms of an effective bilateral or
multilateral mutual recognition agreement or arrangement (MRA) to which
the United States is a party, bodies outside the United States shall be
permitted to authorize equipment in lieu of the Commission. A body in an
MRA partner economy may authorize equipment to U.S. requirements only if
that economy permits bodies in the United States to authorize equipment
to its requirements. The authority designating these telecommunication
certification bodies shall meet the following criteria.
(1) The organization accrediting the prospective telecommunication
certification body shall be capable of meeting the requirements and
conditions of ISO/IEC Guide 61.
(2) The organization assessing the telecommunication certification
body shall appoint a team of qualified experts to perform the assessment
covering all of the elements within the scope of accreditation. For
assessment of telecommunications equipment, the areas of expertise to be
used during the assessment shall include, but not be limited to,
electromagnetic compatibility and telecommunications equipment (wired
and wireless).

where interpretations of the regulations or test procedures may be
necessary. The appropriate key certification and laboratory personnel
shall demonstrate a knowledge of how to obtain current and correct
technical regulation interpretations. The competence of the
telecommunication certification body shall be demonstrated by
assessment. The general competence, efficiency, experience, familiarity
with technical regulations and products included in those technical
regulations, as well as compliance with applicable parts of the ISO/IEC
Guides 25 and 65, shall be taken into consideration.
(5) A TCB shall participate in any consultative activities,
identified by the Commission or NIST, to facilitate a common
understanding and interpretation of applicable regulations.
(6) The Commission will provide public notice of the specific
methods that will be used to accredit TCBs, consistent with these
qualification criteria.
(d) Sub-contractors. (1) In accordance with the provisions of sub-
clause 4.4 of ISO/IEC Guide 65, the testing of a product, or a portion
thereof, may be performed by a sub-contractor of a designated TCB,
provided the laboratory has been assessed by the TCB as competent and in
compliance with the applicable provisions of ISO/IEC Guide 65 and other
relevant standards and guides.
(2) When a subcontractor is used, the TCB shall be responsible for
the test results and shall maintain appropriate oversight of the
subcontractor to ensure reliability of the test results. Such oversight
shall include periodic audits of products that have been tested.
(e) Designation of TCBs. (1) The Commission will designate as a TCB
any organization that meets the qualification criteria and is accredited
by NIST or its recognized accreditor.
(2) The Commission will withdraw the designation of a TCB if the
TCB's accreditation by NIST or its recognized accreditor is withdrawn,
if the Commission determines there is just cause for withdrawing the
designation, or if the TCB requests that it no longer hold the
designation. The Commission will provide a TCB with 30 days notice of
its intention to withdraw the designation and provide the TCB with an
opportunity to respond.
(3) A list of designated TCBs will be published by the Commission.
(f) Scope of responsibility. (1) TCBs shall certify equipment in
accordance with the Commission's rules and policies.
(2) A TCB shall accept test data from any source, subject to the
requirements in ISO/IEC Guide 65, and shall not unnecessarily repeat
tests.
(3) TCBs may establish and assess fees for processing certification
applications and other tasks as required by the Commission.
(4) A TCB may rescind a grant of certification within 30 days of
grant for administrative errors. After that time, a grant can only be
revoked by the Commission through the procedures in Sec. 2.939 of this
part. A TCB shall notify both the applicant and the Commission when a
grant is rescinded.
(5) A TCB may not:
(i) Grant a waiver of the rules, or certify equipment for which the
Commission rules or requirements do not exist or for which the
application of the rules or requirements is unclear.

[63 FR 36600, July 7, 1998]
Sec. 2.1043 Changes in certificated equipment.
(a) Except as provided in paragraph (b)(3) of this section, changes
to the basic frequency determining and stabilizing circuitry (including
clock or data rates), frequency multiplication stages, basic modulator
circuit or maximum power or field strength ratings shall not be
performed without application for and authorization of a new grant of
certification. Variations in electrical or mechanical construction,
other than these indicated items, are permitted provided the variations
either do not affect the characteristics required to be reported to the
Commission or the variations are made in compliance with the other
provisions of this section. Changes to the software installed in a
transmitter that do not affect the radio frequency emissions do not
require a filing with the Commission and may be made by parties other
than the holder of the grant of certification.
(b) Three classes of permissive changes may be made in certificated
equipment without requiring a new application for and grant of
certification. None of the classes of changes shall result in a change
in identification.
(1) A Class I permissive change includes those modifications in the
equipment which do not degrade the characteristics reported by the
manufacturer and accepted by the Commission when certification is
granted. No filing with the Commission is required for a Class I
permissive change.
(2) A Class II permissive change includes those modifications which
degrade the performance characteristics as reported to the Commission at
the
[[Page 660]]
time of the initial certification. Such degraded performance must still
meet the minimum requirements of the applicable rules. When a Class II
permissive change is made by the grantee, the grantee shall supply the
Commission with complete information and the results of tests of the
characteristics affected by such change. The modified equipment shall
not be marketed under the existing grant of certification prior to
acknowledgement by the Commission that the change is acceptable.
(3) A Class III permissive change includes modifications to the
software of a software defined radio transmitter that change the
frequency, modulation type, output power or maximum field strength
outside the parameters previously approved. When a Class III permissive
change is made, the grantee shall supply the Commission with a
description of the changes and test results showing that the equipment
complies with the applicable rules with the new software loaded,
including compliance with the applicable RF exposure requirements. The
modified software shall not be loaded into equipment, and the equipment
shall not be marketed with the modified software under the existing
grant of certification, prior to acknowledgement by the Commission that
the change is acceptable. A copy of the software shall be submitted to
the Commission upon request. Class III changes are permitted only for
equipment in which no Class II changes have been made from the
originally approved device.
Note to paragraph (b)(3):
Any software change that degrades spurious and out-of-band emissions
previously reported to the Commission at the time of initial
certification would be considered a change in frequency or modulation
and would require a Class III permissive change or new equipment
authorization application.
(4) Class I and Class II permissive changes may only be made by the
holder of the grant of certification, except as specified below.
(c) A grantee desiring to make a change other than a permissive
change shall file an application on FCC Form 731 accompanied by the
required fees. The grantee shall attach a description of the change(s)
to be made and a statement indicating whether the change(s) will be made
in all units (including previous production) or will be made only in
those units produced after the change is authorized.
(d) A modification which results in a change in the identification
of a device with or without change in circuitry requires a new
application for, and grant of certification. If the changes affect the
characteristics required to be reported, a complete application shall be
filed. If the characteristics required to be reported are not changed
the abbreviated procedure of Sec. 2.933 may be used.
(e) Equipment that has been certificated or formerly type accepted
for use in the Amateur Radio Service pursuant to the requirements of
part 97 of this chapter may be modified without regard to the conditions
specified in paragraph (b) of this section, provided the following
conditions are met:
(1) Any person performing such modifications on equipment used under
part 97 of this chapter must possess a valid amateur radio operator
license of the class required for the use of the equipment being
modified.
(2) Modifications made pursuant to this paragraph are limited to
equipment used at licensed amateur radio stations.
(3) Modifications specified or performed by equipment manufacturers
or suppliers must be in accordance with the requirements set forth in
paragraph (b) of this section.
(4) Modifications specified or performed by licensees in the Amateur
Radio Service on equipment other than that at specific licensed amateur
radio stations must be in accordance with the requirements set forth in
paragraph (b) of this section.
(5) The station licensee shall be responsible for ensuring that
modified equipment used at his station will comply with the applicable
technical standards in part 97 of this chapter.
(f) For equipment other than that operating under parts 15 or 18,
when a Class II permissive change is made by other than the grantee of
certification, the information and data specified in paragraph (b)(2) of
this section shall be supplied by the person making the change. The
modified equipment shall not be operated under an authorization
[[Page 661]]
of the Commission prior to acknowledgement by the Commission that the
change is acceptable.
(g) The interconnection of a certificated or formerly type accepted
AM broadcast stereophonic exciter-generator with a certificated or
formerly type accepted AM broadcast transmitter in accordance with the
manufacturer's instructions and upon completion of measurements showing
that the modified transmitter meets the emission limitation requirements
of Sec. 73.44 is defined as a Class I permissive change for compliance
with this section.
(h) The interconnection of a multiplexing exciter with a
certificated or formerly type accepted AM broadcast transmitter in
accordance with the manufacturer's instructions without electrical or
mechanical modification of the transmitter circuits and completion of
equipment performance measurements showing the transmitter meets the
minimum performance requirements applicable thereto is defined as a
Class I permissive change for compliance with this section.
(i) The addition of TV broadcast subcarrier generators to a
certificated or formerly type accepted TV broadcast transmitter or the
addition of FM broadcast subcarrier generators to a type accepted FM
broadcast transmitter, provided the transmitter exciter is designed for
subcarrier operation without mechanical or electrical alterations to the
exciter or other transmitter circuits.
(j) The addition of TV broadcast stereophonic generators to a
certificated or formerly type accepted TV broadcast transmitter or the
addition of FM broadcast stereophonic generators to a certificated or
formerly type accepted FM broadcast transmitter, provided the
transmitter exciter is designed for stereophonic sound operation without
mechanical or electrical alterations to the exciter or other transmitter
circuits.
(k) The addition of subscription TV encoding equipment for which the
FCC has granted advance approval under the provisions of Sec. 2.1400 in
subpart M and Sec. 73.644(c) of part 73 to a certificated or formerly
type accepted transmitter is considered a Class I permissive change.
(l) Notwithstanding the provisions of this section, broadcast
licensees or permittees are permitted to modify certificated or formerly
type accepted equipment pursuant to Sec. 73.1690 of the FCC's rules.

test frequencies. In the event it is either impractical or impossible to
make open field measurements (e.g. a broadcast transmitter installed in
a building) measurements will be accepted of the equipment as installed.
Such measurements must be accompanied by a description of the site where
the measurements were made showing the location of any possible source
of reflections which might distort the field strength measurements.
Information submitted shall include the relative radiated power of each
spurious emission with reference to the rated power output of the

frequency determining and stabilizing circuitry need be subjected to the
temperature variation test.
(c) In addition to all other requirements of this section, the
following information is required for equipment incorporating heater
type crystal oscillators to be used in mobile stations, for which type
acceptance is first requested after March 25, 1974, except for battery
powered, hand carried, portable equipment having less than 3 watts mean
output power.

frequency to stabilize within the applicable tolerance. Tests shall be
made after temperature stabilization at each of the ambient temperature
levels; the lower temperature limit, 0[deg] centigrade and +30[deg]
centigrade with no primary power applied.
(2) Beginning at each temperature level specified in paragraph
(c)(1) of this section, the frequency shall be measured within one
minute after application of primary power to the transmitter and at
intervals of no more than one minute thereafter until ten minutes have
elapsed or until sufficient measurements are obtained to indicate
clearly that the frequency has stabilized within the applicable
tolerance, whichever time period is greater. During each test, the
ambient temperature shall not be allowed to rise more than 10[deg]
centigrade above the respective beginning ambient temperature level.
(3) The elapsed time necessary for the frequency to stabilize within
the applicable tolerance from each beginning ambient temperature level
as determined from the tests specified in this paragraph shall be

this test because of its physical dimensions or power rating, only its
frequency determining and stabilizing portions need be tested.
(d) The frequency stability shall be measured with variation of
primary supply voltage as follows:
(1) Vary primary supply voltage from 85 to 115 percent of the
nominal value for other than hand carried battery equipment.
(2) For hand carried, battery powered equipment, reduce primary
supply voltage to the battery operating end point which shall be
specified by the manufacturer.
[[Page 667]]
(3) The supply voltage shall be measured at the input to the cable
normally provided with the equipment, or at the power supply terminals
if cables are not normally provided. Effects on frequency of transmitter
keying (except for broadcast transmitters) and any heating element

Radiofrequency Radiation Exposure
Sec. 2.1091 Radiofrequency radiation exposure evaluation: mobile devices.
(a) Requirements of this section are a consequence of Commission
responsibilities under the National Environmental Policy Act to evaluate
the environmental significance of its actions. See subpart I of part 1
of this chapter, in particular Sec. 1.1307(b).
(b) For purposes of this section, a mobile device is defined as a
transmitting device designed to be used in other than fixed locations
and to generally be used in such a way that a separation distance of at
least 20 centimeters is normally maintained between the transmitter's
radiating structure(s) and the body of the user or nearby persons. In
this context, the term ``fixed location'' means that the device is
physically secured at one location and is not able to be easily moved to
another location. Transmitting devices designed to be used by consumers
or workers that can be easily re-located, such as wireless devices
associated with a personal computer, are considered to be mobile devices
if they meet the 20 centimeter separation requirement.
(c) Mobile devices that operate in the Cellular Radiotelephone
Service, the Personal Communications Services, the Satellite
Communications Services, the General Wireless Communications Service,
the Wireless Communications Service, the Maritime Services and the
Specialized Mobile Radio Service authorized under subpart H of part 22
of this chapter, parts 24, 25, 26 and 27 of this chapter, part 80 of
this chapter (ship earth stations devices only) and part 90 of this
chapter are subject to routine environmental evaluation for RF exposure
prior to equipment authorization or use if they operate at frequencies
of 1.5 GHz or below and their effective radiated power (ERP) is 1.5
watts or more, or if they operate at frequencies above 1.5 GHz and their
ERP is 3 watts or more. Unlicensed personal communications service
devices, unlicensed millimeter wave devices and unlicensed NII devices
authorized under Sec. Sec. 15.253, 15.255, and 15.257, and subparts D
and E of part 15 of this chapter are also subject to routine
environmental evaluation for RF exposure prior to equipment
authorization or use if their ERP is 3 watts or more or if they meet the
definition of a portable device as specified in Sec. 2.1093(b)
requiring evaluation under the provisions of that section. All other
mobile and unlicensed transmitting devices are categorically excluded
from routine environmental evaluation for RF exposure prior to equipment
authorization or use, except as specified in Sec. Sec. 1.1307(c) and
1.1307(d) of this chapter. Applications for equipment authorization of
mobile and unlicensed transmitting devices subject to routine
environmental evaluation must contain a statement confirming compliance
with the limits specified in paragraph (d) of this section as part of
their application. Technical information showing the basis for this
statement must be submitted to the Commission upon request.
(d) The limits to be used for evaluation are specified in Sec.
1.1310 of this chapter. All unlicensed personal communications service
(PCS) devices and unlicensed NII devices shall be subject to the limits
for general population/uncontrolled exposure.
(1) For purposes of analyzing mobile transmitting devices under the
occupational/controlled criteria specified in Sec. 1.1310 of this
chapter, time-averaging provisions of the guidelines may be used in
conjunction with typical maximum duty factors to determine maximum
likely exposure levels.
(2) Time-averaging provisions may not be used in determining typical
exposure levels for devices intended for use by consumers in general
population/uncontrolled environments as defined in Sec. 1.1310 of this
chapter. However, ``source-based'' time-averaging
[[Page 672]]
based on an inherent property or duty-cycle of a device is allowed. An
example of this is the determination of exposure from a device that uses
digital technology such as a time-division multiple-access (TDMA) scheme
for transmission of a signal. In general, maximum average power levels
must be used to determine compliance.
(3) If appropriate, compliance with exposure guidelines for devices
in this section can be accomplished by the use of warning labels and by
providing users with information concerning minimum separation distances
from transmitting structures and proper installation of antennas.
(4) In some cases, e.g., modular or desktop transmitters, the
potential conditions of use of a device may not allow easy
classification of that device as either mobile or portable (also see
Sec. 2.1093). In such cases, applicants are responsible for determining
minimum distances for compliance for the intended use and installation
of the device based on evaluation of either specific absorption rate
(SAR), field strength or power density, whichever is most appropriate.

Sec. 2.1093 Radiofrequency radiation exposure evaluation: portable devices.
(a) Requirements of this section are a consequence of Commission
responsibilities under the National Environmental Policy Act to evaluate
the environmental significance of its actions. See subpart I of part 1
of this chapter, in particular Sec. 1.1307(b).
(b) For purposes of this section, a portable device is defined as a
transmitting device designed to be used so that the radiating
structure(s) of the device is/are within 20 centimeters of the body of
the user.
(c) Portable devices that operate in the Cellular Radiotelephone
Service, the Personal Communications Service (PCS), the Satellite
Communications Services, the General Wireless Communications Service,
the Wireless Communications Service, the Maritime Services, the
Specialized Mobile Radio Service, the 4.9 GHz Band Service, the Wireless
Medical Telemetry Service (WMTS) and the Medical Implant Communications
Service (MICS), authorized under subpart H of part 22 of this chapter,
parts 24, 25, 26, 27, 80 and 90 of this chapter, subparts H and I of
part 95 of this chapter, and unlicensed personal communication service,
unlicensed NII devices and millimeter wave devices authorized under
subparts D and E, Sec. Sec. 15.253, 15.255 and 15.257 of this chapter
are subject to routine environmental evaluation for RF exposure prior to
equipment authorization or use. All other portable transmitting devices
are categorically excluded from routine environmental evaluation for RF
exposure prior to equipment authorization or use, except as specified in
Sec. Sec. 1.1307(c) and 1.1307(d) of this chapter. Applications for
equipment authorization of portable transmitting devices subject to
routine environmental evaluation must contain a statement confirming
compliance with the limits specified in paragraph (d) of this section as
part of their application. Technical information showing the basis for
this statement must be submitted to the Commission upon request.
(d) The limits to be used for evaluation are based generally on
criteria published by the American National Standards Institute (ANSI)
for localized specific absorption rate (``SAR'') in Section 4.2 of
``IEEE Standard for Safety Levels with Respect to Human Exposure to
Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz,'' ANSI/IEEE
C95.1-1992, Copyright 1992 by the Institute of Electrical and
Electronics Engineers, Inc., New York, New York 10017. These criteria
for SAR evaluation are similar to those recommended by the National
Council on Radiation Protection and Measurements (NCRP) in ``Biological
Effects and Exposure Criteria for Radiofrequency Electromagnetic
Fields,'' NCRP Report No. 86, Section 17.4.5. Copyright NCRP, 1986,
Bethesda, Maryland 20814. SAR is a measure of the rate of energy
absorption due to exposure to an RF transmitting source. SAR values have
been related to threshold levels for potential biological hazards. The
criteria to be used are specified in paragraphs (d)(1) and (d)(2)
[[Page 673]]
of this section and shall apply for portable devices transmitting in the
frequency range from 100 kHz to 6 GHz. Portable devices that transmit at
frequencies above 6 GHz are to be evaluated in terms of the MPE limits
specified in Sec. 1.1310 of this chapter. Measurements and calculations
to demonstrate compliance with MPE field strength or power density
limits for devices operating above 6 GHz should be made at a minimum
distance of 5 cm from the radiating source.
(1) Limits for Occupational/Controlled exposure: 0.4 W/kg as
averaged over the whole-body and spatial peak SAR not exceeding 8 W/kg
as averaged over any 1 gram of tissue (defined as a tissue volume in the
shape of a cube). Exceptions are the hands, wrists, feet and ankles
where the spatial peak SAR shall not exceed 20 W/kg, as averaged over an
10 grams of tissue (defined as a tissue volume in the shape of a cube).
Occupational/Controlled limits apply when persons are exposed as a
consequence of their employment provided these persons are fully aware
of and exercise control over their exposure. Awareness of exposure can
be accomplished by use of warning labels or by specific training or
education through appropriate means, such as an RF safety program in a
work environment.
(2) Limits for General Population/Uncontrolled exposure: 0.08 W/kg
as averaged over the whole-body and spatial peak SAR not exceeding 1.6
W/kg as averaged over any 1 gram of tissue (defined as a tissue volume
in the shape of a cube). Exceptions are the hands, wrists, feet and
ankles where the spatial peak SAR shall not exceed 4 W/kg, as averaged
over any 10 grams of tissue (defined as a tissue volume in the shape of
a cube). General Population/Uncontrolled limits apply when the general
public may be exposed, or when persons that are exposed as a consequence
of their employment may not be fully aware of the potential for exposure
or do not exercise control over their exposure. Warning labels placed on
consumer devices such as cellular telephones will not be sufficient
reason to allow these devices to be evaluated subject to limits for
occupational/controlled exposure in paragraph (d)(1) of this section.
(3) Compliance with SAR limits can be demonstrated by either
laboratory measurement techniques or by computational modeling.
Methodologies and references for SAR evaluation are described in
numerous technical publications including ``IEEE Recommended Practice
for the Measurement of Potentially Hazardous Electromagnetic Fields--RF
and Microwave,'' IEEE C95.3-1991.
(4) For purposes of analyzing portable transmitting devices under
the occupational/controlled criteria, the time-averaging provisions of
the MPE guidelines identified in Sec. 1.1310 of this chapter can be
used in conjunction with typical maximum duty factors to determine
maximum likely exposure levels.
(5) Time-averaging provisions of the MPE guidelines identified in
Sec. 1.1310 of this chapter may not be used in determining typical
exposure levels for portable devices intended for use by consumers, such
as hand-held cellular telephones, that are considered to operate in
general population/uncontrolled environments as defined above. However,
``source-based'' time-averaging based on an inherent property or duty-
cycle of a device is allowed. An example of this would be the
determination of exposure from a device that uses digital technology
such as a time-division multiple-access (TDMA) scheme for transmission
of a signal. In general, maximum average power levels must be used to
determine compliance.

[[Page 674]]
equipment. The technical standards applicable to individual types of
equipment are found in that part of the rules governing the service
wherein the equipment is to be operated. In addition to the technical
standards, the rules governing the service may require that such
equipment receive an equipment authorization from the Commission as a
prerequisite for marketing and importing this equipment into the U.S.A.
The marketing rules, Sec. 2.801 et seq., were adopted pursuant to the
authority in section 302 of the Communications Act of 1934, as amended
(47 U.S.C. 302).
(b) The rules in this section set out the conditions under which
radio frequency devices as defined in Sec. 2.801 that are capable of
causing harmful interference to radio communications may be imported
into the U.S.A.
(c) Nothing in this section prevents importers from shipping goods
into foreign trade zones or Customs bonded warehouses, such as is the
prescribed procedure under Sec. 2.1204(a)(5). Radio frequency devices
capable of causing harmful interference, however, cannot be withdrawn
from these areas except in accordance with the provisions of this
section.

Subpart N_FCC Procedure for Testing Class A, B and S Emergency Position
Indicating Radiobeacons (EPIRBs)
Source: 56 FR 11683, Mar. 20, 1991, unless otherwise noted.
General
Sec. 2.1501 Introduction.
The procedure described herein sets forth uniform methods for
testing Class A, B and S Emergency Position Indicating Radiobeacons
(EPIRBs) for compliance with the applicable portions of the FCC Rules
and Regulations. Other methods and test results may be used provided
they are fully documented and deemed by the Commission to yield results
equivalent to the procedures set forth in this section.
Sec. 2.1503 Test environment.
(a) Measurement sites. Radiated emission tests for peak effective
radiated power (PERP), spurious emissions and power in the test mode are
to be performed on an open field test site as shown in Figure 1. The
site is to be located on level ground with an obstruction-free, 60 m by
52 m, elliptical area. The site is to be equipped with an antenna mast
capable of adjustment from 1 to 4 m. The center of a metal ground plane
at least one wavelength in diameter at 121.5 MHz (2.47 m) is to be
located 30 m from the receiving antenna. The ground plane is to have
provisions for mounting removable quarter-wave verticle elements to
produce a
[[Page 678]]
monopole antenna at both 121.5 and 243 MHz with the VSWR of less than
1.5.
Note: It is desirable that the level of radiated ambient EME at the
test site be at least 6 dB below the FCC limits applicable to the EPIRB.
It is, of course, not always possible to meet this condition. If the
ambient field strength at some frequencies within the specified
measurement ranges is too high, it is recommended that one or more of
the following corrective steps be employed:
(1) Perform measurements in critical frequency bands during hours
when broadcast and other radio stations are off-the-air and ambients
from industrial equipment are lower.
(2) Insofar as is possible, orient the axis of an open area test
site to discriminate against strong ambient signals.
(3) Vary the bandwidth of the measuring instrument to separate
ambient EME from emissions from the EPIRB.
(b) Temperature. Except as otherwise noted, the ambient temperature
during testing is to be within the range of 4 to 35 [deg]C (40 to 95
[deg]F).
Sec. 2.1505 Test instrumentation and equipment.
(a) Receiver (field intensity meter). A calibrated field intensity
meter (FIM) with a frequency range of 30 to 1000 MHz is required for
measuring radiated emission levels. This instrument should be capable of
making peak measurements with a bandwidth of 100 kHz.
(b) Spectrum analyzer. Spectral measurements are to be made with a
spectrum analyzer with a minimum resolution bandwidth no greater than 10
Hz. The video filter, if used, should have a bandwidth wide enough so as
to not affect peak readings. A linear video output is desirable for
performing measurements of modulation characteristics.
(c) Storage oscilloscope. Measurements of modulation characteristics
are to be made using a calibrated storage oscilloscope. This instrument
is to be DC coupled and capable of manually triggered single sweeps.
(d) Frequency counter. A frequency counter with an accuracy of at
least 5 parts per million is required for measuring the carrier
frequency.
(e) Signal generator. A calibrated signal generator with an output
of at least 75 mW at 121.5 and 243 MHz is required for generating a
reference signal for site calibration.
(f) Antenna. Radiated emissions are to be measured with calibrated,
tuned, half-wave dipole antennas covering the frequency range of 30 to
1000 MHz.
(g) Temperature chamber. Tests which call for subjecting the EPIRB
to temperature levels other than the ambient temperature are to be
performed in a temperature test chamber which can be adjusted to stable
temperatures from -20 to +55 [deg]C. This chamber is to be of sufficient
size to accommodate the EPIRB under test.
(h) Vibration table. A vibration table capable of vibrating the
EPIRB with a sinusoidal motion is required. The table must be capable of
varying the frequency of vibration either linearly or logarithmically
over a range of 4 to 33 Hz with maximum peak amplitudes of up to 2.5 mm.
(i) Salt fog chamber. A chamber capable of producing salt fog at a
temperature of 35 [deg]C for 48 hours is required. This chamber is to be
of sufficient size to accommodate the EPIRB under test.
(j) Drop test facility. A facility which will permit dropping an
EPIRB from a height of 20 m into water is required. The water must be
deep enough so that the EPIRB will not touch bottom when dropped.
Environmental and Operational Test Procedures
Sec. 2.1507 Test frequencies.
Testing of an EPIRB for compliance outside a shielded room on a
distress frequency is prohibited, since this may interfere with
emergency communications. Therefore, all compliance testing outside a
shielded room should be conducted on one of the pairs of alternate
frequencies specified below:
121.600/243.200 MHz
121.650/243.300 MHz
121.700/243.400 MHz
121.750/243.500 MHz
121.800/243.600 MHz
121.850/243.700 MHz
121.900/243.800 MHz
The above frequencies are to be used for limited testing of EPIRBs for
compliance with FCC Rules, subject to the following conditions:
[[Page 679]]
(a) The testing shall not cause harmful interference to authorized
communications on these frequencies.
(b) The testing shall be coordinated with the nearest FCC district
office.
For simplicity, 121.5 MHz and 243 MHz will be used throughout this test
procedure to indicate the alternate test frequency.

(e) are to be conducted on a single test unit in the order given below.
This sequence of tests also includes the electrical tests in Sec. Sec.
2.1511, 2.1513 and 2.1515 of this part. The test unit is not to be
adjusted, nor is the battery to be replaced during these tests, and a
log of battery on-time should be maintained. The above tests are to be
performed on the same test unit. The tests in Sec. 2.1509 (f) through
(i) may be run in any sequence or may be performed on separate test
units.

10-15 0.8
15-25 0.4
25-33 0.2
B. The frequency is to be changed either linearly or logarithmically
with time between 4 Hz and 33 Hz such that a complete cycle (4 Hz to 33
Hz to 4 Hz) takes approximately 5 minutes.
C. The EPIRB is to be vibrated for at least 30 minutes or six
complete cycles.
Step (3) Remount the EPIRB, if necessary, and repeat step 2 for each

Step (1) Place the EPIRB in a salt fog chamber for a period of at
least 2 hours at a temperature of 35 [deg]C (2
[deg]C) before exposing it to salt fog. The EPIRB is to be turned off
during this test.
Step (2) With the chamber temperature maintained at 35 [deg]C,
introduce salt fog at the saturation point for 48 hours. The salt fog is
to be prepared from a 5% (1%) salt (sodium
chloride solution. For detailed guidance on the preparation of the
solution and the apparatus for generating salt fog, refer to MIL-STD-
810D (19 July 1983), method 509.2.
Step (3) Upon completion of the salt fog exposure, the EPIRB is to
be airdried at room temperature for 12 hours and operation verified by
turning the unit on and observing the RF power indicator on the unit or
monitoring the transmission with a receiver. Record observations.
(d) Drop test. This test is to be performed on EPIRB which are
required or intended to float.
Step (1) Turn the EPIRB on, log the time and drop it three times
into water from a height of 20 meters. The water is to be deep enough so
that the EPIRB does not touch bottom when dropped. Each drop should be
initiated from a different orientation as follows: antenna vertical up;
antenna vertical down; antenna horizontal.
Step (2) Upon completion of the drop test, an exterior mechanical
inspection is to be
[[Page 680]]
performed and operation verified by observing the RF power indicator on
the unit or monitoring the transmission with a receiver. Record
observations. Turn the test unit off and log the total on-time.
(e) Forty-eight hour operational test. This test includes the
battery life test and all the electrical tests given in Sec. Sec.
2.1511, 2.1513 and 2.1515 of this part, at various temperatures. The
tests are to be performed on the same EPIRB in the sequence specified
herein. Be sure to record the on-time of the unit during each test. No
more than 8 hours of total on-time is permitted before commencing step
4. When operating the EPIRB in the environmental chamber, a non-
radiating load may be substituted for the antenna provided it is
electrically equivalent to the standard antenna and does not reduce the
battery current drain.
Step (1) Perform the radiated emissions test in Sec. 2.1511 of this
part.
Step (2) Perform the modulation characteristic tests in Sec. 2.1513
of this part.
Step (3) Perform the spectral tests in Sec. 2.1515 of this part.
Step (4) With the EPIRB off, place unit in an environmental chamber
at a temperature of -20 [deg]C for at least 2 hours.
Step (5) With the EPIRB in the chamber, repeat the carrier frequency
test in Sec. 2.1515(d) of this part. (Leave the EPIRB turned on.)
Step (6) Near the end of 48 hours of total on-time for the EPIRB,
repeat the carrier frequency test in Sec. 2.1515(d) of this part.
Step (7) At the end of 48 hours of total on-time, remove EPIRB from
the chamber and immediately repeat the PERP test for the fundamental
emissions in Sec. 2.1511(c) of this part. The unit should be maintained
at -20 [deg]C to the extent possible for this test.
(f) Float free and activation test. This test is required only for
Class A EPIRBs.
Step (1) The EPIRB is to be installed in the automatic release
mechanism and the assembly is to be mounted on a fixture simulating a
deck or bulkhead as per manufacturer' installation instructions.
Step (2) Submerge the fixture in water in its normal mounted
orientation. The EPIRB must float free before reaching a depth of 4
meters and should automatically activate. Activation is to be verified
by observing the RF power indicator on the unit or monitoring the
transmission with a receiver.
If the EPIRB is equipped with an automatically deployable antenna, the
antenna must properly deploy during each immersion. Record observations.
(g) Stability and buoyancy test. This test is to be performed on
EPIRBs which are required or intended to float. This test is to be
conducted in fresh water.
Step (1) With the antenna deployed in its normal operating position,
submerge the EPIRB in a horizontal position just below the surface of
the water.
Step (2) Release the EPIRB and observe the amount of time required
for it to come to an upright position. It must reach its upright
position within one second from each position.
The EPIRB must have a reserve buoyancy of at least 5% of its gross
weight. It must also float upright in calm water with the base of the
antenna a minimum of 5 cm above the water. Record the time required for
the test unit to right itself.
(h) Temperature/frequency test. The frequency stability shall be
measured over an ambient temperature from -20[deg] to +55 [deg]C at
intervals of not more than 10 [deg]C. A period of time sufficient to
stabilize all of the components of the oscillator circuit at each
temperture level shall be allowed prior to frequency measurement.
Step (1) Place the EPIRB in the environmental test chamber.
Step (2) Adjust the temperature in the chamber to +20 [deg]C and
allow sufficient time for the oscillator to stabilize at that
temperature.
Step (3) Measure the carrier frequency in accordance with the
procedure in Sec. 2.1515(d) of this part. Record the carrier frequency
in Hertz. The carrier frequency at +20 [deg]C is the reference for
determining the frequency tolerance.
Step (4) Increase the temperature in the chamber to +55 [deg]C and
allow sufficient time for the oscillator to stabilize at that
temperature. Measure the carrier frequency using the procedure in Sec.
2.1515(d) of this part.
Step (5) Reduce the temperature in the chamber in 10 [deg]C maximum
increments until -20 [deg]C is reached. At each new temperature, allow
sufficient time for the oscillator to stabilize at that temperature.
Measure the temperature and frequency in each case and plot the
frequency vs temperature from -20[deg] to +55 [deg]C.
(i) Leakage and immersion test.
Step (1) Completely submerge the EPIRB in water for 48 hours. The
EPIRB is to be turned off during this test.
Step (2) Remove the EPIRB from the water and wipe dry.
Step (3) Verify operation by briefly turning the EPIRB on and
observing the RF power
[[Page 681]]
indicator on the unit or monitoring the transmission with a receiver.
Step (4) Open the EPIRB for examination. There is to be no water
inside the unit. Record observations.
Sec. 2.1511 Measurements of radiated emissions.
The Commission's Rules require that the peak efficetive radiated
power (PERP) of a Class A, B or S EPIRB not be less than 75 mW under
certain specified conditions. The PERP of an EPIRB transmitter is
determined by comparing its level to a reference PERP generated by a
standard quarter-wave monopole antenna located on a one wavelength
minimum diameter metal ground plane. The Rules also require that all
spurious and harmonic emissions be attenuated by a specified amount with
respect to the reference PERP. In addition, there is a limit on the PERP
of radiated emissions with the switch in the test mode. These
measurements are to be made in accordance with the following procedure.
(a) General set-up instructions. Measurements of radiated
electromagnetic emissions (EME) are to be performed on the 30 meter open
field test site described in Sec. 2.1503(a) of this part and on one of
the pair of frequencies listed in Sec. 2.1507 of this part. A receiver,
tuned dipole antennas and a calibrated signal generator as described in
Sec. 2.1505 of this part are required. The EPIRB should be powered by
its own internal battery with its standard antenna attached and
deployed.
(b) Set-up for radiated EME tests.
Step (1) Place a 121.5 MHz quarter-wave vertical antenna element at
the center of the ground plane and connect the output of the calibrated
signal generator to the antenna.
Step (2) Mount the tuned dipole antenna on the antenna mast, tune
the elements to 121.5 MHz and connect the antenna to the receiver.
Step (3) After an appropriate warm up, turn the receiver to the
frequency of the test unit, set the detector to peak mode and the
bandwidth to 100 kHz.
(Note: It is sometimes helpful to monitor the receiver audio output
with a speaker. The EPIRB signal may be identified by its distinctive
modulation.)
(c) Radiated EME tests.
Fundamental emissions-peak effective radiated power
Step (1) Turn on the signal generator and adjust the output to 75 mW
at 121.5 MHz.
Step (2) Vary the antenna height from one to four meters in both
vertical and horizontal polarization. Record the highest receiver
reading in dBm as the reference level.
Step (3) Disconnect the signal generator and replace the quarter-
wave vertical element on the ground plane with the EPIRB under test. The
EPIRB is to be positioned directly on the surface of and in the center
of the metal ground plane.
Step (4) Activate the EPIRB.
Step (5) Vary the receive antenna height from one to four meters in
both vertical and horizontal polarization. Record the highest receiver
reading in dBm and the instrument settings, antenna height and direction
for maximum radiation, antenna polarization and conversion factors, if
any, associated with that reading.
Step (6) Repeat Step 5 with the EPIRB switch in the test position.
Return the switch to the normal operation position.
Step (7) Rotate the EPIRB 30 degrees and repeat Steps 5 and 6.
Repeat this step for all successive 30 degrees segments of a full, 360
degree rotation of the EPIRB.
Step (8) Repeat Sec. 2.1511(b) and Steps 1 through 7 for 243 MHz.
Step (9) Compute the peak effective radiated power for the maximum
level of each measured emission using the following formula:
[GRAPHIC] [TIFF OMITTED] TC03JN91.001
where:
dBmmeas is the measured receiver reading in dBm, and
dBmref is the reference receiver reading found in step 2 of
Sec. 2.1511(c).
Step (10) Record the PERP in mW. The FCC limit for minimum power in
the normal operation mode (i.e., with the EPIRB switch in the normal
operating position) is 75 mW. The FCC limit for maximum power in the
test mode is 0.0001 mW.
Spurious emissions
Step (11) Reset the signal generator to operate at 121.5 MHz.
Step (12) For each spurious and harmonic emission to be measured,
retune the receive antenna to the appropriate frequency and repeat Steps
5 and 7.
Step (13) Determine the FCC limit on power for spurious emissions on
the frequency of each measured emission as follows:
The rules require that spurious emissions be attenuated at least 30
decibels below the
[[Page 682]]
transmit power level. Therefore, the maximum received power limit for a
spurious emission can be calculated from the formula:
dBmspur = dBmmeas+AF121.5-
AFspurfreq-30
where:
dBmmeas = measured receiver reading (Section 2.1511(c), step
5).
AF121.5 = tuned dipole antenna factor at 121.5 MHz.
AFspurfreq = tuned dipole antenna factor at spurious freq.
Step (14) Record in dB below the fundamental emissions the level of
all spurious and harmonic emissions within 10 dB of the FCC limits.
Sec. 2.1513 Measurements of modulation characteristics.
(a) Set-up. Test of modulation characteristics are to be performed
in an RF shielded room.
Step (1) Place the EPIRB directly on a metal ground plane, such as
the shielded room floor.
Step (2) Place a suitable receiving antenna at a convenient distance
from the EPIRB and connect it to the input of the spectrum analyzer or
receiver to observe the radiated signal from the EPIRB.
Step (3) Set the spectrum analyzer or receiver controls as follows:
I.F. bandwidth: 300 kHz minimum
Video filter: OFF or as wide as possible
Amplitude scale: Linear
Frequency: 121.5 MHz
Scan width: 0 Hz
Step (4) Connect the detected output of the spectrum analyzer or
receiver to the input of the storage oscilloscope.
Step (5) Set the oscilloscope controls as necessary to allow the
demodulated waveform to be viewed. The input signal is to be DC coupled.
(b) Measurement of Audio Frequencies.
Step (1) Activate the EPIRB.
Step (2) Trigger the oscilloscope and store at least one complete
cycle of the audio waveform.
Step (3) Measure the period (T) of the waveform. The period is the
time difference between the half voltage points at the beginning and end
of one complete cycle of the waveform. See Figure 2.
Step (4) Calculate the frequency (F), where:
F=1/T.
Step (5) Repeat Steps 2 through 4 until the highest and lowest audio
frequencies are found.
Note: The lowest and highest frequencies may occur several cycles
before or after the transition from low to high frequency.)
Step (6) Determine the audio frequency range (Frange),
where:
Frange=Fhigh-Flow
Step (7) Record instrument settings and the lowest and highest audio
frequencies. Record the audio frequency range in Hertz.
Step (8) Repeat Steps 1-7, above, for 243 MHz.
(c) Modulation factor.
Step (1) Activate the EPIRB.
Step (2) Trigger the oscilloscope and store at least one complete
cycle of the audio waveform. The input signal is to be DC coupled or
erroneous results will be obtained.
Step (3) Measure the maximum voltage (Vmax), and the
minimum voltage (Vmin) for the cycle. The modulation factor
(M) is calculated from the following formula:
[GRAPHIC] [TIFF OMITTED] TC03JN91.002
See Figure 2.
Step (4) Repeat Steps 2 and 3 until the lowest modulation factor is
found.
Step (5) Record instrument settings and the lowest modulation
factor, expressed as a ratio between 0 and 1.
Step (6) Repeat the above measurements for 243 MHz.
(d) Modulation duty cycle.
Step (1) Activate the EPIRB.
Step (2) Trigger the oscilloscope and store at least one complete
cycle of the audio waveform.
Step (3) Measure the period (T) of the waveform. The period is the
time difference between the half voltage points at the beginning and end
of one cycle of the waveform. See Figure 2.
Step (4) Measure the pulse width (tp) of the waveform.
The pulse width is the time difference between the half voltage points
on the rising and falling portions of the waveform. See Figure 2.
Step (5) Calculate the duty cycle (D) as follows:
[GRAPHIC] [TIFF OMITTED] TC03JN91.003
Step (6) Repeat Steps 2 through 5 a sufficient number of times to
determine the highest and lowest duty cycles.
Step (7) Record instrument settings and the highest and lowest duty
cycles in percent.
Step (8) Repeat Steps 1-7 for 243 MHz.
(e) Sweep repetition rate.
Step (1) Connect a speaker to the detected output of the spectrum
analyzer or receiver
[[Page 683]]
so the audio frequencies are audible. Alternatively, an FM radio tuned
to 108 MHz placed in the vicinity of the EPIRB may be used.
Step (2) Activate the EPIRB.
Step (3) Time the number of audio sweeps (N) for a one minute
interval.
Step (4) Calculate the audio sweep rate (R) using R=N/60.
Step (5) Record instrument settings and the sweep repetition rate in
Hertz.
Sec. 2.1515 Spectral measurements.
(a) Set-up. Spectral measurements are to be performed in a shielded
room.
Step (1) Place the EPIRB directly on a metal ground plane, such as
the shielded room floor. The EPIRB should be powered by its own internal
battery with its standard antenna attached and deployed.
Step (2) Place a suitable receiving antenna at a convenient distance
from the EPIRB and connect it to the input of the spectrum analyzer to
observe the radiated signal from the EPIRB. A signal generator and
frequency counter capable of operating at 121.5 and 243 MHz are also
required for these tests.
(b) Occupied bandwidth test.
Step (1) Activate the EPIRB and observe the fundamental frequency on
a spectrum analyzer. Adjust location of receiving antenna and spectrum
analyzer controls to obtain a suitable signal level (i.e., a level which
will not overload the spectrum analyzer, but is far enough above the
noise floor to allow determination of whether or not the sidebands are
attenuated by at least the amount required in the rules).
Step (2) Set spectrum analyzer controls as follows:
I.F. bandwidth: 10 kHz
Video filter: OFF or as wide as possible
Scan time: 100 ms./div.
Amplitude scale: 10 dB/div.
Scan width: 20 Hz/div.
Center frequency: 121.5 MHz
Step (3) Record the signal level in dbm.

Scan time: 10 sec./div.
Amplitude scale: 10 dB/div.
Scan width: 20 kHz/div.
Step (6) Check the modulation sidebands for compliance with the
required attenuation below the mean power reference level specified in
Sec. 80.211 of the rules.
Step (7) Record how the test was performed, instrument settings and
the occupied bandwidth in kHz and the 3 dB bandwidth of the carrier in
Hz. (See Sec. 2.1517 of this part).
Step (8) Repeat Steps 1 through 7 for the signal at 243 MHz.
(c) Signal enhancement test. The setup specified in Sec. 2.1515(a)
is to be used in this method of measuring signal enhancement. Other
methods may be used if shown to give results equivalent to or more
accurate than this method.
Step (1) Activate the EPIRB and locate the carrier frequency at
121.5 MHz on the spectrum analyzer. Adjust location of receiving antenna
and spectrum analyzer controls to obtain a suitable signal level (i.e.,
a level which will not overload the analyzer, but is far enough above
the noise floor to allow sidebands at least 40 dB below the carrier to
be viewed).
Step (2) Set the spectrum analyzer controls as follows:
I.F. bandwidth: 10 kHz
Video filter: OFF or as wide as possible
Scan time: 100 ms./div.
Amplitude scale: 5 dB/div.
Scan width: 10 kHz/div.
Center frequency: 121.5 MHz
Step (3) Record the amplitude in dBm.
Step (4) Calculate the total power output by adding 10 log(D), where
D is the modulation duty cycle determined in Sec. 2.1513(d) of this
part, to the recorded signal level.
Step (5) Set the spectrum analyzer controls as follows:
I.F. bandwidth: 60 Hz or less
Video filter: OFF or as wide as possible
Scan time: 10 sec./div.
Amplitude scale: 5 dB/div.
Scan width: 20 Hz/div.
Center frequency: 121.5 MHz
Step (6) Measure and record the carrier power dBm as displayed on
the spectrum analyzer.
Step (7) Calculate the ratio of carrier power to total power from
Steps 4 and 6 using the following formula:
[GRAPHIC] [TIFF OMITTED] TC03JN91.004
dBC = carrier power in step 6
dBT = total power in step 4
Step (8) Record instrument settings, sample calculation and the
percent of power within 30 Hz at 121.5 MHz or
60 Hz at 243 MHz of the carrier frequency.
Step (9) Repeat the above measurement Steps 1 through 8 for 243 MHz.
For the higher frequency, the I.F. bandwidth in step 5 must be 120 Hz or
less.
[[Page 684]]
(d) Carrier frequency test. The setup specified in Sec. 2.1515(a)
is to be used in measuring the carrier frequency.
Step (1) Activate the EPIRB and locate the 121.5 MHz signal on the
spectrum analyzer. Adjust location of receiving antenna and spectrum
analyzer controls to obtain a suitable signal level.
Step (2) Set the spectrum analyzer controls as follows:
I.F. bandwidth: 100 Hz
Video filter: OFF or as wide as possible
Scan time: 10 sec./div.
Amplitude scale: 10 dB/div.
Scan width: 20 Hz/div.
Center frequency: 121.5 MHz
Step (3) Combine the output of the signal generator with the EPIRB
signal at the input to the spectrum analyzer.
Step (4) Adjust amplitude and frequency of signal generator output
to determine center of carrier frequency component.
Step (5) Measure signal generator frequency with frequency counter
with accuracy of 5 PPM or better and record as carrier frequency.
Step (6) If applicable, change the type of modulation of the EPIRB
and record the shift in carrier frequency as observed on the spectrum
analyzer display.
Step (7) Repeat the above measurement Steps 1 through 6 for 243 MHz.
