EXPLANATION
The Code of Federal Regulations is a codification of the general and
permanent rules published in the Federal Register by the Executive
departments and agencies of the Federal Government. The Code is divided
into 50 titles which represent broad areas subject to Federal
regulation. Each title is divided into chapters which usually bear the
name of the issuing agency. Each chapter is further subdivided into
parts covering specific regulatory areas.
Each volume of the Code is revised at least once each calendar year
and issued on a quarterly basis approximately as follows:
Title 1 through Title 16.................................as of January 1
Title 17 through Title 27..................................as of April 1
Title 28 through Title 41...................................as of July 1
Title 42 through Title 50................................as of October 1
The appropriate revision date is printed on the cover of each
volume.
LEGAL STATUS
The contents of the Federal Register are required to be judicially
noticed (44 U.S.C. 1507). The Code of Federal Regulations is prima facie
evidence of the text of the original documents (44 U.S.C. 1510).
HOW TO USE THE CODE OF FEDERAL REGULATIONS
The Code of Federal Regulations is kept up to date by the individual
issues of the Federal Register. These two publications must be used
together to determine the latest version of any given rule.
To determine whether a Code volume has been amended since its
revision date (in this case, October 1, 1996), consult the ``List of CFR
Sections Affected (LSA),'' which is issued monthly, and the ``Cumulative
List of Parts Affected,'' which appears in the Reader Aids section of
the daily Federal Register. These two lists will identify the Federal
Register page number of the latest amendment of any given rule.
EFFECTIVE AND EXPIRATION DATES
Each volume of the Code contains amendments published in the Federal
Register since the last revision of that volume of the Code. Source
citations for the regulations are referred to by volume number and page
number of the Federal Register and date of publication. Publication
dates and effective dates are usually not the same and care must be
exercised by the user in determining the actual effective date. In
instances where the effective date is beyond the cut-off date for the
Code a note has been inserted to reflect the future effective date. In
those instances where a regulation published in the Federal Register
states a date certain for expiration, an appropriate note will be
inserted following the text.
OMB CONTROL NUMBERS
The Paperwork Reduction Act of 1980 (Pub. L. 96-511) requires
Federal agencies to display an OMB control number with their information
collection request.
[[Page vi]]
Many agencies have begun publishing numerous OMB control numbers as
amendments to existing regulations in the CFR. These OMB numbers are
placed as close as possible to the applicable recordkeeping or reporting
requirements.
OBSOLETE PROVISIONS
Provisions that become obsolete before the revision date stated on
the cover of each volume are not carried. Code users may find the text
of provisions in effect on a given date in the past by using the
appropriate numerical list of sections affected. For the period before
January 1, 1986, consult either the List of CFR Sections Affected, 1949-
1963, 1964-1972, or 1973-1985, published in seven separate volumes. For
the period beginning January 1, 1986, a ``List of CFR Sections
Affected'' is published at the end of each CFR volume.
INCORPORATION BY REFERENCE
What is incorporation by reference? Incorporation by reference was
established by statute and allows Federal agencies to meet the
requirement to publish regulations in the Federal Register by referring
to materials already published elsewhere. For an incorporation to be
valid, the Director of the Federal Register must approve it. The legal
effect of incorporation by reference is that the material is treated as
if it were published in full in the Federal Register (5 U.S.C. 552(a)).
This material, like any other properly issued regulation, has the force
of law.
What is a proper incorporation by reference? The Director of the
Federal Register will approve an incorporation by reference only when
the requirements of 1 CFR part 51 are met. Some of the elements on which
approval is based are:
(a) The incorporation will substantially reduce the volume of
material published in the Federal Register.
(b) The matter incorporated is in fact available to the extent
necessary to afford fairness and uniformity in the administrative
process.
(c) The incorporating document is drafted and submitted for
publication in accordance with 1 CFR part 51.
Properly approved incorporations by reference in this volume are
listed in the Finding Aids at the end of this volume.
What if the material incorporated by reference cannot be found? If
you have any problem locating or obtaining a copy of material listed in
the Finding Aids of this volume as an approved incorporation by
reference, please contact the agency that issued the regulation
containing that incorporation. If, after contacting the agency, you find
the material is not available, please notify the Director of the Federal
Register, National Archives and Records Administration, Washington DC
20408, or call (202) 523-4534.
CFR INDEXES AND TABULAR GUIDES
A subject index to the Code of Federal Regulations is contained in a
separate volume, revised annually as of January 1, entitled CFR Index
and Finding Aids. This volume contains the Parallel Table of Statutory
Authorities and Agency Rules (Table I), and Acts Requiring Publication
in the Federal Register (Table II). A list of CFR titles, chapters, and
parts and an alphabetical list of agencies publishing in the CFR are
also included in this volume.
An index to the text of ``Title 3--The President'' is carried within
that volume.
The Federal Register Index is issued monthly in cumulative form.
This index is based on a consolidation of the ``Contents'' entries in
the daily Federal Register.
[[Page vii]]
A List of CFR Sections Affected (LSA) is published monthly, keyed to
the revision dates of the 50 CFR titles.
REPUBLICATION OF MATERIAL
There are no restrictions on the republication of material appearing
in the Code of Federal Regulations.

arrival at the United States port. The application must be submitted to
the Commission's Engineer in Charge of the FCC District Office nearest
the port of arrival. The application must include:
(i) The ship's name and radio call sign;
(ii) The name of the first United States port of arrival directly
from a foreign port;
(iii) The date of arrival;
(iv) The date and port at which annual inspection will be formally
requested to be conducted;
(v) Reason for requesting waiver; and
(vi) A statement that the ship's compulsory radio equipment is
operable.
(e) Compensation for overtime services. Under section 4(f)(3) of the
Communications Act, Engineers in Charge and Radio Engineers of the
Compliance and Information Bureau of the Federal Communications
Commission who may be required to remain on duty to perform services in
connection with the inspection of ship radio equipment and apparatus for
the purpose of Part II of Title III of the Communications Act or the
Great Lakes Radio Agreement at night or on Sundays and holidays must
receive extra compensation to be paid by the master, owner, or agent of
the vessel under the following regulations:
(1) The rates of extra compensation are payable in cases where the
services of such engineers have been duly requested and they have
reported for duty, even though no actual service may be performed.
(2) The extra compensation for overtime services is in addition to
the regular compensation paid by the government in the cases of
engineers whose compensation is fixed on the ordinary per diem basis and
those receiving compensation per month or per annum.
(3) Extra compensation for waiting time will not be allowed unless
and until the engineer actually reports for duty.
(4) For the purpose of computing extra compensation, the word night
means the time between the established closing hour of one day at the
office involved and the established opening hour of the following
business day at such office, but will not include any such time within
the 24 hours of a Sunday or holiday. Each Sunday and each holiday will
comprise the 24 hours between midnight and midnight. For the
[[Page 28]]
purposes of this section, the time between the established closing hour
of an office and midnight of the day immediately preceding a Sunday or
holiday and the time from midnight until the established opening hour of
the day immediately following the Sunday or holiday will be considered
as a single night. The term holiday includes only government recognized
holidays, and such other days as may be designated national holidays by
the President or Congress.
(5) For authorized service in excess of 8 hours on any day excluding
Sunday and holidays, extra compensation equivalent to one-half day's pay
is payable for each 2 hours or fraction thereof of at least 1 hour that
the overtime extends beyond the 8 hours when the overtime is not less
than 1 hour. The maximum amount which may be paid for authorized
overtime services on any day other than on a Sunday or holiday must not
exceed 2\1/2\ days' pay.
(6) In computing the amount earned for overtime at the rate of
``one-half day's pay for each 2 hours or fraction thereof of at least 1
hour that the overtime extends beyond the established closing hour'',
one-half day's pay must be one-half of the gross daily rate of pay; each
2 hours is the time period for the purpose of computation; at least 1
hour means the minimum service in any 2-hour overtime period for which
extra pay may be granted, and each additional period in the amount of 2
hours or fraction thereof of at least 1 hour will entitle the engineer
to an additional one-half day's pay. Payment of extra compensation for
services consisting of at least 1 hour is authorized from the
established closing hour, even though such services may not actually
begin until later, Provided, That the engineer rendering the service
remained on duty after the established closing hour, in which case the
time between the established closing hour, and the time of beginning the
actual services must be computed as waiting time. Where the performance
of actual service is preceded by such a waiting time there should be an
affirmative statement that the engineer was required to remain on duty
between the established closing hour and the time of beginning the
actual services.
(7) In computing extra compensation where the services rendered are
in broken periods, the time served should be combined with the waiting
time and computed as continuous service.
(8) The same considerations must apply when charging for waiting
time as govern the charge for services actually rendered. No charge
should be made unless after having reported for duty the waiting time
amounts to at least 1 hour.
(9) For any authorized services performed on Sundays and holidays,
totalling not more than 8 hours, extra compensation is payable
equivalent to two day's pay in addition to any regular compensation for
such days. For any authorized service in excess of 8 hours (starting
either before or after 5 p.m. local time) extra compensation at the rate
of one-half days' pay, based on the normal daily rate of pay, for each
two hours of service or fraction thereof of not less than 1 hour, is
payable in addition to the extra compensation payable for service up to
and including 8 hours of service. The maximum extra compensation payable
for work on Sundays and holidays is 4\1/2\ days' pay.
(10) When engineers are in travel status overtime will apply the
same as if they were at an official station. However, compensation for
such overtime must not include travel time.
(11) Assessments and collection of fees against steamship companies
for overtime services must be made even though the payment to employees
for such services may not be made until funds are appropriated for that
purpose.
(12) An application on FCC Form 808 must be filed with the office
being requested to furnish overtime services before such assignment can
be made.
(13) Overtime services must be billed to the steamship companies as
soon as possible after the services have been performed and on a
collection voucher (FCC Form 907). Remittance shall be by postal money
order or certified check payable to the Collector of Customs, Treasury
Department and forwarded to that officer at the port indicated on the
voucher, who shall in turn deposit such remittance on a properly
designated receipt account.
[[Page 29]]
(14) Protests against the extraction of extra compensation must be
forwarded to the Commission at Washington, DC, and a copy sent to the
office which furnished the overtime services.

Sec. 80.98 Radiotelegraph testing procedures.
(a) Stations authorized to use telegraphy may conduct tests on any
assigned frequency. Emissions must not cause harmful interference. When
radiation is necessary the radiotelegraph testing procedure described in
this paragraph must be followed:
(1) The operator must not interfere with transmissions in progress.
(2) The operator must transmit ``IE'' (two dots, space, one dot) on
the test frequency as a warning that test emissions are about to be
made. When the frequency of the test emission is within the frequency
band 405-525 kHz, a watch must be maintained on 500 kHz throughout the
test period.
(3) If any station transmits ``AS'' (wait), testing must be
suspended. When transmission of ``IE'' is resumed and no response is
heard, the test may proceed.
(4) Test signals composed of a series of ``VVV'' having a duration
of not more than ten seconds, followed by the call sign of the testing
station will be transmitted. The call sign must be sent clearly at a
speed of approximately 10 words per minute. This test transmission must
not be repeated until a period of at least one minute has elapsed. On
500 kHz in a region of heavy traffic, at least five minutes must elapse
before the test transmission is repeated.
(b) When testing is conducted on 500 kHz, no tests will be conducted
during the 500 kHz silence periods. Care must be exercised not to so
prolong and space the dash portion of the ``VVV'' series as to form the
alarm signal.
(c) When testing is conducted on any frequency in the band 8362-8366
kHz, tests must not actuate any automatic alarm receiver.
[[Page 35]]
Sec. 80.99 Radiotelegraph station identification.
This section applies to coast, ship and survival craft stations
authorized to transmit in the band 405-525 kHz.
(a) The station transmitting radiotelegraph emissions must be
identified by its call sign. The call sign must be transmitted with the
telegraphy emission normally used by the station. The call sign must be
transmitted at 20 minute intervals when transmission is sustained for
more than 20 minutes. When a ship station is exchanging public
correspondence communications, the identification may be deferred until
completion of each communication with any other station.
(b) The requirements of this section do not apply to survival craft
stations when transmitting distress signals automatically or when
operating on 121.500 MHz for radiobeacon purposes.
(c) Emergency position indicating radiobeacon stations do not
require identification.
Sec. 80.100 Morse code requirement.
The code employed for telegraphy must be the Morse code specified in
the Telegraph Regulations annexed to the International Telecommunication
Convention. Pertinent extracts from the Telegraph Regulations are
contained in the ``Manual for Use by the Maritime Mobile and Maritime
Mobile-Satellite Services'' published by the International
Telecommunication Union.
Sec. 80.101 Radiotelephone testing procedures.
This section is applicable to all stations using telephony except
where otherwise specified.
(a) Station licensees must not cause harmful interference. When
radiation is necessary or unavoidable, the testing procedure described
below must be followed:
(1) The operator must not interfere with transmissions in progress.
(2) The testing station's call sign, followed by the word ``test'',
must be announced on the radio-channel being used for the test.
(3) If any station responds ``wait'', the test must be suspended for
a minimum of 30 seconds, then repeat the call sign followed by the word
``test'' and listen again for a response. To continue the test, the
operator must use counts or phrases which do not conflict with normal
operating signals, and must end with the station's call sign. Test
signals must not exceed ten seconds, and must not be repeated until at
least one minute has elapsed. On the frequency 2182 kHz or 156.800 MHz,
the time between tests must be a minimum of five minutes.
(b) Testing of transmitters must be confined to single frequency
channels on working frequencies. However, 2182 kHz and 156.800 MHz may
be used to contact ship or coast stations as appropriate when signal
reports are necessary. Short tests on 2182 kHz by vessels with DSB (A3)
equipment for distress and safety purposes are permitted to evaluate the
compatibility of that equipment with an A3J emission system. U.S. Coast
Guard stations may be contacted on 2182 kHz or 156.800 MHz for test
purposes only when tests are being conducted during inspections by
Commission representatives, when qualified radio technicians are
installing or repairing the station radiotelephone equipment, or when
qualified ship's personnel conduct an operational check requested by the
U.S. Coast Guard. In these cases the test must be identified as ``FCC''
or ``technical''.
(c) Survival craft transmitter tests must not be made within
actuating range of automatic alarm receivers. Survival craft
transmitters must not be tested on the frequency 500 kHz during the
silence periods.
Sec. 80.102 Radiotelephone station identification.
This section applies to all stations using telephony which are
subject to this part.
(a) Except as provided in paragraphs (d) and (e) of this section,
stations must give the call sign in English. Identification must be
made:
(1) At the beginning and end of each communication with any other
station.

particular station(s) with which it intends to communicate.
(2) Coast stations must call ship stations by voice unless it is
known that the particular ship station may be contacted by other means
such as automatic actuation of a selective ringing or calling device.
(3) Coast stations may be authorized emission for selective calling
on each working frequency.
(4) Calling a particular station must not continue for more than one
minute in each instance. If the called station does not reply, that
station must not again be called for two minutes. When a called station
does not reply to a call sent three times at intervals of two minutes,
the calling must cease for fifteen minutes. However, if harmful
interference will not be caused to other communications in progress, the
call may be repeated after three minutes.
(5) A coast station must not attempt to communicate with a ship
station that has specifically called another coast station until it
becomes evident that the called station does not answer, or that
communication between the ship station and the called station cannot be
carried on because of unsatisfactory operating conditions.
(6) Calls to establish communication must be initiated on an
available common working frequency when such a frequency exists and it
is known that the called ship maintains a simultaneous watch on the
common working frequency and the appropriate calling frequency(ies).

Sec. 80.213 Modulation requirements.
(a) Transmitters must meet the following modulation requirements:
(1) When double sideband emission is used the peak modulation must
be maintained between 75 and 100 percent;
(2) When phase or frequency modulation is used in the 156-162 MHz
and 216-220 MHz bands the peak modulation must be maintained between 75

as 100 percent peak modulation; and
(3) In single sideband operation the upper sideband must be
transmitted. Single sideband transmitters must automatically limit the
peak envelope power to their authorized operating power and meet the
requirements in Sec. 80.207(c).
(b) Radiotelephone transmitters using A3E, F3E and G3E emission must
have a modulation limiter to prevent any modulation over 100 percent.
This requirement does not apply to survival craft transmitters, to
transmitters that do not require a license or to transmitters whose
output power does not exceed 3 watts.
(c) Coast station transmitters operated in the 72.0-73.0 MHz and
75.4-76.0 MHz bands must be equipped with an audio low-pass filter. The
filter must be installed between the modulation limiter and the
modulated radio frequency stage. At frequencies between 3 kHz and 15 kHz
it must have an attenuation greater than at 1 kHz by at least
40log10 (f/3) dB where ``f'' is the frequency in kilohertz. At
frequencies above 15 kHz the attenuation must be at least 28 dB greater
than at 1 kHz.
(d) Ship and coast station transmitters operating in the 156-162 MHz
and
[[Page 54]]
216-220 MHz bands must be capable of proper operation with a frequency
deviation of plus-minus5 kHz when using any emission authorized by
Sec. 80.207.
(e) Coast station transmitters operated in the 156-162 MHz band must
be equipped with an audio low-pass filter. The filter must be installed
between the modulation limiter and the modulated radio frequency stage.
At frequencies between 3 kHz and 20 kHz it must have an attenuation
greater than at 1 kHz by at least 60log10 (f/3) dB where ``f'' is
the audio frequency in kilohertz. At frequencies above 20 kHz the
attenuation must be at least 50 dB greater than at 1 kHz.
(f) Radiodetermination ship stations operating on 154.585 MHz,
159.480 MHz, 160.725 MHz, 160.785 MHz, 454.000 MHz and 459.000 MHz must
employ a duty cycle with a maximum transmission period of 60 seconds
followed by a minimum quiescent period four times the duration of the
transmission period.
(g) Radar stations operating in the bands above 2.4 GHz may use any
type of modulation consistent with the bandwidth requirements in
Sec. 80.209(b).
(h) Radar transponder coast stations using the 2920-3100 MHz or
9320-9500 MHz band must operate in a variable frequency mode and respond
on their operating frequencies with a maximum error equivalent to 100
meters. Additionally, their response must be encoded with a Morse
character starting with a dash. The duration of a Morse dot is defined
as equal to the width of a space and \1/3\ of the width of a Morse dash.
The duration of the response code must not exceed 50 microseconds. The
sensitivity of the stations must be adjustable so that received signals
below -10 dBm at the antenna will not activate the transponder. Antenna
polarization must be horizontal when operating in the 9320-9500 MHz band
and either horizontal or both horizontal and vertical when operating in
the 2920-3100 MHz band. Racons using frequency agile transmitting
techniques must include circuitry designed to reduce interference caused
by triggering from radar antenna sidelobes.
(i) Variable frequency ship station transponders operating in the
2920-3100 MHz or 9320-9500 MHz band that are not used for search and
rescue purposes must meet the following requirements:
(1) Non-selectable transponders must have the following
characteristics:
(i) They must respond on all their frequencies with a maximum range
error equivalent to 100 meters;
(ii) They must use a Morse encoding of ``PS'' (dot-dash-dash-dot,
dot-dot-dot), meaning ``You should not come any closer''. The width of a
Morse dot is defined as equal to the width of a space and \1/3\ of the
width of a Morse dash;
(iii) When they employ swept frequency techniques they must not
transmit on any frequency for more than 10 seconds in any 120 second
period;
(iv) Any range offset of their response must occur during their
pause on the fixed frequency;
(v) The duration of the response code must not exceed 50
microseconds;
(vi) The sensitivity of the stations must be adjustable so that
received signals below -10 dBm at the antenna input will not activate
the transponder;
(vii) Antenna polarization must be horizontal when operating in the
9320-9500 MHz band and either horizontal or both horizontal and vertical
when operating in the 2920-3100 MHz band.
(viii) Transponders using frequency agile techniques must include
circuitry designed to reduce interference caused by triggering from
radar antenna sidelobes.
(2) Selectable transponders must be authorized under part 5 of the
Commission's rules until standards for their use are developed.

Sec. 80.305 Watch requirements of the Communications Act and the Safety Convention.
(a) Each ship of the United States which is equipped with a
radiotelegraph station for compliance with part II of title III of the
Communications Act or chapter IV of the Safety Convention must:
(1) Keep a continuous and efficient watch on 500 kHz by means of
radio officers while being navigated in the open sea outside a harbor or
port. In lieu thereof, on a cargo ship equipped with a radiotelegraph
auto alarm in proper operating condition, an efficient watch on 500 kHz
must be maintained by means of a radio officer for at least 8 hours per
day in the aggregate, i.e., for at least one-third of each day or
portion of each day that the vessel is navigated in the open sea outside
of a harbor or port.
(2) Keep a continuous and efficient watch on the radiotelephone
distress frequency 2182 kHz from the principal radio operating position
or the room from which the vessel is normally steered while being
navigated in the open sea outside a harbor or port. A radiotelephone
distress frequency watch receiver having a loudspeaker and a
radiotelephone auto alarm facility must be used to keep the continuous
watch on 2182 kHz if such watch is kept from the room from which the
vessel is normally steered. After a determination by the master that
conditions are such that maintenance of the listening watch would
interfere with the safe navigation of the ship, the watch may be
maintained by the use of the radiotelephone auto alarm facility alone.
(3) Keep a continuous and efficient watch on the VHF distress
frequency 156.800 MHz from the room from which the vessel is normally
steered while in the open sea outside a harbor or port. The watch must
be maintained by a designated member of the crew who may perform other
duties, relating to the operation or navigation of the vessel, provided
such other duties do not interfere with the effectiveness of the watch.
Use of a properly adjusted squelch or brief interruptions due to other
nearby VHF transmissions are not considered to adversely affect the
continuity or efficiency of the required watch on the VHF distress
frequency. This watch need not be maintained by vessels subject to the
Bridge-to-Bridge Act and participating in a Vessel Traffic Services
(VTS) system as required or recommended by the U.S. Coast Guard, when an
efficient listening watch is maintained on both the bridge-to-bridge
frequency and a separate assigned VTS frequency.
(b) Each cargo ship of the United States which is equipped with a
radiotelephone station for compliance with part II of title III of the
Communications Act or chapter IV of the Safety Convention must while
being navigated outside of a harbor or port:
(1) Keep a continuous watch on 2182 kHz in the room from which the
vessel is normally steered while at sea, whenever such station is not
being used for authorized traffic. Such watch must be maintained by at
least one officer or crewmember who may perform other duties relating to
the operation or navigation of the vessel, provided such other duties do
not interfere with the
[[Page 70]]
watch. A radiotelephone watch receiver having a loudspeaker and a
radiotelephone auto alarm must be used to keep the continuous watch on
2182 kHz. After a determination by the master that maintenance of the
watch would interfere with the safe navigation of the ship, the watch
may be maintained by use of the radiotelephone auto alarm facility
alone.
(2) Keep a continuous watch on 156.800 MHz from the room from which
the vessel is normally steered. The watch must be maintained by a
crewmember who may perform other duties, relating to the operation or
navigation of the vessel, provided such other duties do not interfere
with the watch. Use of properly adjusted squelch of brief interruptions
due to other nearby VHF transmissions are not considered to adversely
affect the watch. This watch need not be maintained by vessels subject
to the Bridge-to-Bridge Act and participating in a Vessel Traffic
Services (VTS) system when a watch is maintained on both the bridge-to-
bridge frequency and a VTS frequency.
(c) Each vessel of the United States transporting more than six
passengers for hire, which is equipped with a radiotelephone station for
compliance with part III of title III of the Communications Act must,
while being navigated in the open sea or any tidewater within the
jurisdiction of the United States adjacent or contiguous to the open
sea, keep a continuous watch on 2182 kHz while the vessel is beyond VHF
communication range of the nearest VHF coast station, whenever the
radiotelephone station is not being used for authorized traffic. A VHF
watch must be kept on 156.800 MHz whenever such station is not being
used for authorized traffic. The VHF watch must be maintained at the
vessel's steering station actually in use by the qualified operator as
defined by Sec. 80.157 or by a crewmember who may perform other duties
relating to the operation or navigation of the vessel, provided such
other duties do not interfere with the watch. The use of a properly
adjusted squelch is not considered to adversely affect the watch. The
VHF watch need not be maintained by vessels subject to the Bridge-to-
Bridge Act and participating in a Vessel Traffic Services (VTS) system
when an efficient listening watch is maintained on both the bridge-to-
bridge frequency and a VTS frequency.
Sec. 80.306 Provisions governing the radiotelegraph watch.
(a) The radio officer must use the main or reserve receiver, and
either headphones or a loudspeaker to keep the watch on 500 kHz.
(b) During the watch, the radio officer may temporarily interrupt
the required watch on 500 kHz while transmitting or receiving signals or
messages to or from a station but only if it is not feasible to
simultaneously handle such traffic and listen on 500 kHz by split
headphones or a loudspeaker. The watch on 500 kHz must, however, without
exception be maintained during the silence periods.
(c) During this watch, on vessels subject to the Communications Act
and the Safety Convention on international voyages, the radio officer
may discontinue listening when handling traffic on other frequencies or
performing other essential radio duties, but only if it is impracticable
to listen by split headphones or loudspeaker. The watch must always be
maintained by a radio officer using headphones or loudspeaker during the
silence periods. The term ``essential radio duties'' in this rule
includes urgent repairs of radiocommunication equipment used for safety
or radio navigational equipment by order of the master.
(d) When authorized by the master, the radio officer may perform
maintenance repair of communications, navigation or other electronic
equipment outside of the radiotelegraph room, provided that the
listening watch on 500 kHz can be maintained by headphones,
loudspeakers, portable receivers, or other suitable means. The watch on
500 kHz must be maintained in the radiotelegraph room during the silence
period.
Sec. 80.307 Compulsory use of radiotelegraph auto alarm.
The radiotelegraph auto alarm required on a cargo ship subject to
the radiotelegraph provisions of part II of title III of the
Communications Act or
[[Page 71]]
the Safety Convention must be in operation, connected to the main
antenna and adjusted for optimum efficiency at all times while the ship
is being navigated in the open sea when a radio officer is not listening
on the frequency 500 kHz, except under the circumstances as set forth in
Sec. 80.306(b).
Sec. 80.308 Watch required by the Great Lakes Radio Agreement.
(a) Each ship of the United States that is equipped with a
radiotelephone station for compliance with the Great Lakes Radio
Agreement must when underway keep a watch on:
(1) 156.800 MHz on board a vessel 20 meters (65 feet) and over in
length, a vessel engaged in towing (See Sec. 80.951(b)), or a vessel
carrying more than 6 passengers for hire. This watch must be maintained
whenever the station is not being used for authorized traffic. However,
a watch on 156.800 MHz need not be maintained by a vessel maintaining a
watch on the bridge-to-bridge frequency 156.650 MHz and participating in
a Vessel Traffic Services (VTS) system and maintaining a watch on the
specified VTS frequency.
(2) 156.650 MHz on board a vessel 38 meters (124 feet) and over in
length, a vessel engaged in towing (See Sec. 80.951(b)), or a vessel
carrying more than six passengers for hire. This watch must be
maintained continuously and effectively. Sequential monitoring is not
sufficient. Portable VHF equipment may be used to meet this requirement.
Vessels are exempted from this requirement while transiting the St.
Lawrence Seaway and complying with the Joint Regulations of the St.
Lawrence Seaway Authority and St. Lawrence Seaway Development
Corporation between the lower exit of St. Lambert Lock at Montreal and
Crossover Island, New York and in the Welland Canal and approaches
between Calling in Point No. 15 and No. 16.
(b) The watch must be maintained by the master, or person designated
by the master, who may perform other duties provided they do not
interfere with the effectiveness of the watch.
[53 FR 17052, May 13, 1988]
Sec. 80.309 Watch required by the Bridge-to-Bridge Act.
In addition to the watch requirement contained in Sec. 80.148, all
vessels subject to the Bridge-to-Bridge Act must keep a watch on the
designated navigational frequency. The watch must be maintained by the
master or person in charge of the vessel or the person designated by the
master or person in charge to pilot or direct the movement of the
vessel. The person standing watch may perform other duties provided such
other duties do not interfere with the watch.

Sec. 80.310 Watch required by voluntary vessels.
Voluntary vessels not equipped with DSC must maintain a watch on
156.800 MHz (channel 16) whenever the radio is operating and is not
being used to communicate. Noncommercial vessels, such as recreational
boats, may alternatively maintain a watch on 156.450 MHz (channel 9) for
call and reply purposes.
[57 FR 19552, May 7, 1992]
Distress, Alarm, Urgency and Safety Procedures
Sec. 80.311 Authority for distress transmission.
A mobile station in distress may use any means at its disposal to
attract attention, make known its position, and obtain help. A distress
call and message, however, must be transmitted only on the authority of
the master or person responsible for the mobile station. No person shall
knowingly transmit, or cause to be transmitted, any false or fraudulent
signal of distress or related communication.
Sec. 80.312 Priority of distress transmissions.
The distress call has absolute priority over all other
transmissions. All stations which hear it must immediately cease any
transmission capable of interfering with the distress traffic
[[Page 72]]
and must continue to listen on the frequency used for the emission of
the distress call. This call must not be addressed to a particular
station. Acknowledgement of receipt must not be given before the
distress message which follows it is sent.
Sec. 80.313 Frequencies for use in distress.
The frequencies specified in the bands below are for use by mobile
stations in distress. The conventional emission is shown. When a ship
station cannot transmit on the designated frequency or the conventional
emission, it may use any available frequency or emission. Frequencies
for distress and safety calling using digital selective calling
techniques are listed in Sec. 80.359(b). Distress and safety NB-DP
frequencies are indicated by footnote 2 in Sec. 80.361(b).
------------------------------------------------------------------------

[51 FR 31213, Sept. 2, 1986; 51 FR 34984, Oct. 1, 1986]
Sec. 80.314 Distress signals.
(a) The international radiotelegraphy distress signal consists of
the group ``three dots, three dashes, three dots'' (... ---...),
symbolized herein by SOS, transmitted as a single signal in which the
dashes are slightly prolonged so as to be distinguished clearly from the
dots.
(b) The international radiotelephone distress signal consists of the
word MAYDAY, pronounced as the French expression ``m'aider''.
(c) These distress signals indicate that a mobile station is
threatened by grave and imminent danger and requests immediate
assistance.
Sec. 80.315 Distress calls.
(a) The radiotelegraph distress call consists of:
(1) The distress signal SOS, sent three times;
(2) The word DE;
(3) The call sign of the mobile station in distress, sent three
times.
(b) The radiotelephone distress call consists of:
(1) The distress signal MAYDAY spoken three times;
(2) The words THIS IS;
(3) The call sign (or name, if no call sign assigned) of the mobile
station in distress, spoken three times.
Sec. 80.316 Distress messages.
(a) The radiotelegraph distress message consists of:
(1) The distress signal SOS;
(2) The name of the mobile station in distress;
(3) Particulars of its position;
(4) The nature of the distress;
(5) The kind of assistance desired;
(6) Any other information which might facilitate rescue.
(b) The radiotelephone distress message consists of:
(1) The distress signal MAYDAY;
(2) The name of the mobile station in distress;
(3) Particulars of its position;
(4) The nature of the distress;
(5) The kind of assistance desired;
(6) Any other information which might facilitate rescue, for
example, the length, color, and type of vessel, number of persons on
board.
(c) As a general rule, a ship must signal its position in latitude
and longitude, using figures for the degrees and minutes, together with
one of the words NORTH or SOUTH and one of the words EAST or WEST. In
radiotelegraphy, the signal .-.-.- must be used to separate the degrees
from the minutes. When practicable, the true bearing and distance in
nautical miles from a known geographical position may be given.
Sec. 80.317 Radiotelegraph and radiotelephone alarm signals.
(a) The international radiotelegraph alarm signal consists of a
series of twelve dashes sent in one minute, the duration of each dash
being four seconds and the duration of the interval between consecutive
dashes one second. The purpose of this special signal is the
[[Page 73]]
actuation of automatic devices giving the alarm to attract the attention
of the operator when there is no listening watch on the distress
frequency.
(b) The international radiotelephone alarm signal consists of two
substantially sinusoidal audio frequency tones transmitted alternately.
One tone must have a frequency of 2200 Hertz and the other a frequency
of 1300 Hertz, the duration of each tone being 250 milliseconds. When
generated by automatic means, the radiotelephone alarm signal must be
transmitted continuously for a period of at least 30 seconds, but not
exceeding one minute; when generated by other means, the signal must be
transmitted as continuously as practicable over a period of
approximately one minute. The purpose of this special signal is to
attract the attention of the person on watch or to actuate automatic
devices giving the alarm.
Sec. 80.318 Use of alarm signals.
(a) The radiotelegraph or radiotelephone alarm signal, as
appropriate, must only be used to announce:
(1) That a distress call or message is about to follow;
(2) The transmission of an urgent cyclone warning. In this case the
alarm signal may only be used by coast stations authorized by the
Commission to do so; or
(3) The loss of a person or persons overboard. In this case the
alarm signal may only be used when the assistance of other ships is
required and cannot be satisfactorily obtained by the use of the urgency
signal only, but the alarm signal must not be repeated by other
stations. The message must be preceded by the urgency signal.
(b) In cases described in paragraphs (a)(2) and (3) of this section,
the transmission of the warning or message by radiotelegraphy must not
begin until two minutes after the end of the radiotelegraph alarm
signal.
Sec. 80.319 Radiotelegraph distress call and message transmission procedure.
(a) The radiotelegraph distress procedure consists of the following
six steps: however, when time is vital, the first and second steps may
be omitted. These two steps of the distress procedure may also be
omitted in circumstances when transmission of the alarm signal is
considered unnecessary:
(1) The radiotelegraph alarm signal;
(2) The distress call and an interval of two minutes;
(3) The distress call;
(4) The distress message;
(5) Two dashes of ten to fifteen seconds each;
(6) The call sign of the mobile station in distress.
(b) The radiotelegraph distress transmissions must be sent by means
of the international Morse code at a speed not exceeding 16 words per
minute nor less than 8 words per minute.
(c) The distress message, preceded by the distress call, must be
repeated at intervals, especially during the 500 kHz international
silence periods, until an answer is received. The radiotelegraph alarm
signal may also be repeated, if necessary.
(d) The transmissions under paragraphs (a)(5) and (6) of this
section, which are to permit direction finding stations to determine the
position of the station in distress, may be repeated at frequent
intervals if necessary.
(e) When the mobile station in distress receives no answer to a
distress message transmitted on the distress frequency, the message may
be repeated on any other available frequency on which attention might be
attracted.
Sec. 80.320 Radiotelephone distress call and message transmission procedure.
(a) The radiotelephone distress procedure consists of:
(1) The radiotelephone alarm signal (whenever possible);
(2) The distress call;
(3) The distress message.
(b) Radiotelephone distress transmissions must be made slowly and
distinctly, each word being clearly pronounced to facilitate
transcription.
(c) After the transmission by radiotelephony of its distress
message, the mobile station may be requested to transmit suitable
signals followed by its call sign or name, to permit direction-finding
stations to determine its
[[Page 74]]
position. This request may be repeated at frequent intervals if
necessary.
(d) The distress message, preceded by the distress call, must be
repeated at intervals until an answer is received. This repetition must
be preceded by the radiotelephone alarm signal whenever possible.
(e) When the mobile station in distress receives no answer to a
distress message transmitted on the distress frequency, the message may
be repeated on any other available frequency on which attention might be
attracted.
Sec. 80.321 Acknowledgement of receipt of distress message.
(a) Stations of the maritime mobile service which receive a distress
message from a mobile station which is beyond any possible doubt in
their vicinity must immediately acknowledge receipt. However, in areas
where reliable communication with one or more coast stations is
practicable, ship stations may defer this acknowledgement for a short
interval so that a coast station may acknowledge receipt.
(b) Stations of the maritime mobile service which receive a distress
message from a mobile station which beyond any possible doubt is not in
their vicinity, must allow a short interval of time to elapse before
acknowledging receipt of the message in order to permit stations nearer
to the mobile station in distress to acknowledge receipt without
interference.
Sec. 80.322 Form of acknowledgement.
(a) The acknowledgement of receipt of a radiotelegraph distress
message is transmitted in the following form:
(1) The distress signal SOS;
(2) The call sign of the station sending the distress message, sent
three times;
(3) The word DE;
(4) The call sign of the station acknowledging receipt, sent three
times;
(5) The group RRR;
(6) The message signal SOS.
(b) The acknowledgement of receipt of a radiotelephone distress
message is transmitted in the following form:
(1) The distress signal MAYDAY;
(2) The call sign or other identification of the station sending the
distress message, spoken three times;
(3) The words THIS IS;
(4) The call sign or other identification of the station
acknowledging receipt, spoken three times;
(5) The word RECEIVED;
(6) The distress signal MAYDAY.
Sec. 80.323 Information furnished by an acknowledging station.
(a) Every mobile station which acknowledges receipt of a distress
message must on the order of the master or person responsible for the
ship, aircraft, or other vehicle carrying such mobile station, transmit
as soon as possible the following information in the order shown:
(1) Its identifier;
(2) Its position;
(3) The speed at which it is proceeding towards, and the approximate
time it will take to reach the mobile station in distress.
(b) Before sending this message, the station must ensure that it
will not interfere with the emissions of other stations better situated
to render immediate assistance to the station in distress.
Sec. 80.324 Transmission of distress message by station not itself in distress.
(a) A mobile station or a land station which learns that a mobile
station is in distress must transmit a distress message in any of the
following cases:
(1) When the station in distress cannot transmit the distress
message.
(2) When the master or person responsible for the ship, aircraft, or
other vehicle not in distress, or for the land station, believes that
further help is necessary.
(3) When, although not in a position to assist, it has heard a
distress message which has not been acknowledged. When a mobile station
transmits such a distress message, it must notify the authorities who
may be able to assist.
(b) Transmission must be made on the international distress
frequencies or on any other available frequency on which attention might
be attracted.
(c) Transmission of the distress message must always be preceded by
the call indicated below, which must itself
[[Page 75]]
be preceded whenever possible by the radiotelegraph or radiotelephone
alarm signal. This call consists of:
(1) When radiotelegraphy is used:
(i) The signal DDD SOS SOS SOS DDD:
(ii) The word DE;
(iii) The call sign of the transmitting station, sent three times.
(2) When radiotelephony is used:
(i) The signal MAYDAY RELAY, spoken three times;
(ii) The words THIS IS;
(iii) The call sign or other identification of the transmitting
station, spoken three times.
(d) When the radiotelegraph alarm signal is used, an interval of two
minutes must be allowed, whenever this is considered necessary, before
the transmission of the call mentioned in paragraph (c)(1) of this
section.
Sec. 80.325 Control of distress traffic.
(a) Distress traffic consists of all messages relating to the
immediate assistance required by the mobile station in distress. In
distress traffic, the distress signal must be sent before the call and
at the beginning of the preamble of any radiotelegram.
(b) The control of distress traffic is the responsibility of the
mobile station in distress or of the station which has sent the distress
message. These stations may delegate the control of the distress traffic
to another station.
(c) The station in distress or the station in control of distress
traffic may impose silence either on all stations of the mobile service
in the area or on any station which interferes with the distress
traffic. It must address these instructions ``to all stations'' or to
one station only, according to circumstances. In either case, it must
use one of the following signals which are reserved for use by the
mobile station in distress and for the station controlling distress
traffic:
(1) In radiotelegraphy, the abbreviation QRT, followed by the
distress signal SOS.
(2) In radiotelephony, the signal SEELONCE MAYDAY.
(d) If essential, any station of the mobile service near the ship,
aircraft, or other vehicle in distress may also impose silence. It must
use for this purpose:
(1) In radiotelegraphy, the abbreviation QRT, followed by the word
DISTRESS and its own call sign;
(2) In radiotelephony, the word SEELONCE, followed by the word
DISTRESS and its own call sign or other identification.
Sec. 80.326 Notification of resumption of normal working.
(a) When distress traffic has ceased, or when complete silence is no
longer necessary on a frequency which has been used for distress
traffic, the station which has controlled this traffic must transmit on
that frequency a message addressed ``to all stations'' indicating that
normal working may be resumed.
(1) In radiotelegraphy, this message consists of:
(i) The distress signal SOS;
(ii) The call ``to all stations'' (CQ), sent three times;
(iii) The word DE;
(iv) The call sign of the station sending the message;
(v) The time of handing in the message;
(vi) The name and call sign of the mobile station which was in
distress;
(vii) The service abbreviation QUM.
(2) In radiotelephony, this message consists of:
(i) The distress signal MAYDAY;
(ii) The call ``Hello all stations'', spoken three times;
(iii) The words THIS IS;
(iv) The call sign or other identification of the station sending
the message;
(v) The time of handing in of the message;
(vi) The name and call sign of the mobile station which was in
distress;
(vii) The words SEELONCE FEENEE OR PRU-DONCE.
(b) Until they receive the foregoing message indicating that normal
or limited working may be resumed, all stations which are aware of the
distress traffic, and which are not taking part in it, are forbidden to
transmit on the frequencies on which the distress traffic is taking
place.
[[Page 76]]
Sec. 80.327 Urgency signals.
(a) The urgency signal indicates that the calling station has a very
urgent message to transmit concerning the safety of a ship, aircraft, or
other vehicle, or the safety of a person. The urgency signal must be
sent only on the authority of the master or person responsible for the
mobile station.
(b) In radiotelegraphy, the urgency signal consists of three
repetitions of the group XXX, sent with the individual letters of each
group, and the successive groups clearly separated from each other. It
must be transmitted before the call.
(c) In radiotelephony, the urgency signal consists of three oral
repetitions of the group of words PAN PAN transmitted before the call.
(d) The urgency signal has priority over all other communications
except distress. All mobile and land stations which hear it must not
interfere with the transmission of the message which follows the urgency
signal.
[51 FR 31213, Sept. 2, 1986, as amended at 52 FR 35245, Sept. 18, 1987]
Sec. 80.328 Urgency message.
(a) The urgency signal and call, and the message following it, must
be sent on one of the international distress frequencies. Stations which
cannot transmit on a distress frequency may use any other available
frequency on which attention might be attracted.
(b) Mobile stations which hear the urgency signal must continue to
listen for at least three minutes. At the end of this period, if no
urgency message has been heard, they may resume their normal service.
However, land and mobile stations which are in communication on
frequencies other than those used for the transmission of the urgency
signal and of the call which follows it may continue their normal work
without interruption provided the urgency message is not addressed ``to
all stations''.
(c) When the urgency signal has been sent before transmitting a
message ``to all stations'' which calls for action by the stations
receiving the message, the station responsible for its transmission must
cancel it as soon as it knows that action is no longer necessary. This
message of cancellation must likewise be addressed ``to all stations''.
Sec. 80.329 Safety signals.
(a) The safety signal indicates that the station is about to
transmit a message concerning the safety of navigation or giving
important meteorological warnings.
(b) In radiotelegraphy, the safety signal consists of three
repetitions of the group TTT, sent with the individual letters of each
group, and the successive groups clearly separated from each other. It
must be sent before the call.
(c) In radiotelephony, the safety signal consists of the word
SECURITE, pronounced as in French, spoken three times and transmitted
before the call.
(d) The safety signal and call must be sent on one of the
international distress frequencies (500 kHz or 8364 kHz radiotelegraph;
2182 kHz or 156.8 MHz radiotelephone). Stations which cannot transmit on
a distress frequency may use any other available frequency on which
attention might be attracted.
Sec. 80.330 Safety message.
(a) The safety signal and call must be followed by the safety
message. Where practicable, the safety message should be sent on a
working frequency, and a suitable announcement to this effect must be
made at the end of the call.
(b) Except for the cases mentioned in paragraph (c) of this section,
the safety signal when sent on the frequency 500 kHz must be transmitted
toward the end of the first available silence period; the safety message
must be transmitted immediately after the silence period.
(c) Messages about meteorological warnings, of cyclones, dangerous
ice, dangerous wrecks, or any other imminent danger to marine navigation
must be preceded by the safety signal.
(d) Stations hearing the safety signal must not make any
transmission likely to interfere with the message.
Sec. 80.331 Bridge-to-bridge communication procedure.
(a) Vessels subject to the Bridge-to-Bridge Act transmitting on the
designated navigational frequency must conduct communications in a
format similar to those given below:
[[Page 77]]
(1) This is the (name of vessel). My position is (give readily
identifiable position, course and speed) about to (describe contemplated
action). Out.
(2) Vessel off (give a readily identifiable position). This is (name
of vessel) off (give a readily identifiable position). I plan to (give
proposed course of action). Over.
(3) (Coast station), this is (vessel's name) off (give readily
identifiable position). I plan to (give proposed course of action).
Over.
(b) Vessels acknowledging receipt must answer ``(Name of vessel
calling). This is (Name of vessel answering). Received your call,'' and
follow with an indication of their intentions. Communications must
terminate when each ship is satisfied that the other no longer poses a
threat to its safety and is ended with ``Out''.
(c) Use of power greater than 1 watt in a bridge-to-bridge station
shall be limited to the following three situations:
(1) Emergency.
(2) Failure of the vessel being called to respond to a second call
at low power.
(3) A broadcast call as in paragraph (a)(1) of this section in a
blind situation, e.g., rounding a bend in a river.
Sec. 80.332 Equipment to aid search and rescue operations.
(a) Survival craft stations may transmit distress, urgency and
safety signals, calls and messages.
(b) EPIRB's may transmit only in accordance with the requirements of
subparts V and X of this part.
Sec. 80.333 Stations in the maritime mobile-satellite service.
The provisions of Secs. 80.311 and 80.324 apply to the operations of
ship earth stations in the maritime mobile-satellite service.
Subpart H--Frequencies
Radiotelegraphy
Sec. 80.351 Scope.
The following sections describe the carrier frequencies and general
uses of radiotelegraphy with respect to the following:
--Distress, urgency, safety, call and reply.
--Working.
--Digital selective calling (DSC).
--Narrow-band direct-printing (NB-DP).
--Facsimile.
Sec. 80.353 General uses--radiotelegraphy.
(a) Unless otherwise indicated radiotelegraphy may be used by ship
and public coast stations only.
(b) The signal code for Morse telegraphy must be the international
Morse code signals specified in the Telegraph Regulations annexed to the
International Telecommunication Convention.
(c) To facilitate communications, ship stations transmitting by
means of radiotelegraphy must use the service abbreviations (``Q''
signals) listed in Appendix 14 to the ITU Radio Regulations whenever
practicable.
(d) In order to reduce interference stations must attempt to select
calling frequencies which provide the most favorable propagational
characteristics for effecting reliable communications.
(e) Coast stations may apply to use for telegraphy communications
any additional coast station frequencies that are allocated for such
communications in the 10-27500 kHz band that are not listed in this
part. See the Table of Frequency allocations in Sec. 2.106 of this
chapter. The use of such frequencies will be authorized initially with a
six month provisional period.
(f) Radiotelegraphy stations communicating with a Government station
may transmit on a Government frequency when authorized to do so by the
Government station or agency if the emission, bandwidth and frequency
tolerance of the non-Government station are within the same limits as
the Government station.
Sec. 80.355 Distress, urgency, safety, call and reply Morse code frequencies.
This section describes the distress, urgency, safety, call and reply
carrier frequencies assignable to stations for Morse code
radiotelegraphy.
(a) Frequencies in the 100-160 kHz band. The international calling
frequency in the 100-160 kHz band is 143 kHz using A1A or J2A emission.
When a ship station operating in the 100-160 kHz band desires to
communicate with
[[Page 78]]
a coast station, it must call on the frequency 143 kHz unless the
International List of Coast Stations provides otherwise. Coast stations
must reply on their normal working frequency in this band. Only
individual calls, replies to such calls, and transmission of signals
preparatory to traffic may be transmitted on 143 kHz.
(b) Frequencies in the 405-535 kHz band. (1) The international
distress, urgency, safety, call and reply frequency used by ship and
coast stations operating in the 405-525 kHz band is 500 kHz. A2A and A2B
or H2A and H2B emissions are preferred for distress calls, distress
traffic and for urgency and safety messages. For call and reply messages
A1A or J2A emission must be used. In order to facilitate distress
communications routine correspondence tranmissions on 500 kHz must be
reduced to a minimum.
(2) In Region 2 and areas of heavy traffic ship stations must
request coast stations to listen on the ship station's working
frequencies.
(3) In areas where 500 kHz is used for distress a ship or coast
station must use the supplementary calling frequency 512 kHz for routine
calling and normally request a reply on its working frequency. The
called station may reply on 512 kHz when requested to do so by the
calling station.
(c) Frequencies in the 2000-27500 kHz band--(1) Survival craft
frequencies: Survival craft operating on 8364 kHz must use A2A or H2A
emission to establish communications related to search and rescue
operations.
(2) Ship station frequencies. The following table describes the
calling frequencies in the 4000-27500 kHz band which are available for
use by authorized ship stations equipped with crystal controlled
oscillators for A1A or J2A radiotelegraphy. There are two series of
frequencies for worldwide use and two series of frequencies for each
geographic region. Ship stations with synthesized transmitters may
operate on every full 100 Hz increment in the 0.5 kHz channel for the
frequencies listed, except for 100 Hz above and below those designated
for worldwide use. During normal business hours when not communicating
on other frequencies, all U.S. coast radiotelegraph stations must
monitor the worldwide frequencies and the initial calling frequencies
for the region in which it is located. The specific frequencies which
must be monitored by a coast station will vary with propagation
conditions. The calling frequencies which are routinely monitored by
specific coast stations can be determined by reference to the ITU
publication entitled ``List of Coast Stations''. Initial calls by ship
stations must be made on the appropriate initial calling frequency
first. Calls on the worldwide frequencies may be made only after calls
on the appropriate initial calling frequency are unsuccessful.

Sec. 80.357 Morse code working frequencies.
This section describes the working frequencies assignable to
maritime stations for A1A or J2A radiotelegraphy.
(a) Ship station frequencies--(1) Frequencies in the 100-160 kHz
band. The following table describes the working carrier frequencies in
the 100-160 kHz band which are assignable to ship stations. A ship
station may also transmit on a radiotelegraphy working channel of a
coast station within the 100-160 kHz band when directed to do so by the
coast station provided interference is not caused to any land, fixed,
broadcast, or radiolocation station.

(2) Frequencies in the 405-525 kHz band. The following table
describes the working carrier frequencies in the 405-525 kHz band which
are assignable to ship stations. A ship station may transmit on a
radiotelegraphy working channel of a coast station in the 415-490 kHz
band when directed to do so by the coast station.

\1\ The frequency 410 kHz may be used on a secondary basis for the
transmission of radiodetermination information and for transmitting by
radiotelegraph radiodetermination related messages to direction-
finding stations.
\2\ The frequency 512 kHz may be used as a supplementary calling
frequency when 500 kHz is used for distress, safety and urgency
communications. The use of the 512 kHz as a working frequency is
prohibited in areas where it is used as a supplementary calling
frequency when 500 kHz is used for distress, safety, and urgency
communications.
\3\ The frequency 518 kHz is a receive only frequency by ship stations.
It is used by U.S. Coast Guard coast stations for NB-DP transmissions
of meteorological and navigational warnings to ships.
(3) Frequencies in the 2000-27500 kHz band. This paragraph describes
the working frequencies and Channel Series in the 2000-27500 kHz band
which are assignable to ship stations.
(i) Two Channel Series will be assigned for routine use to each ship
station. Frequencies from any other Channel Series may be used if the
frequencies in the assigned Channel Series are not adequate for
communications.

\1\ All frequencies in this table are shown in kilohertz.
[[Page 86]]
(2) Conditions of use. The following conditions are applicable to
these frequencies:
(i) Frequencies in the 100-160 kHz band are assignable to coast
stations for high seas communications only;
(ii) Frequencies above 5 MHz may be assigned primarily to stations
serving the high seas and secondarily to stations serving inland waters
of the United States, including the Great Lakes, under the condition
that interference will not be caused to any coast station serving the
high seas. Applicants for these frequencies must submit a substantial
showing of need based on the following factors:
(A) A schedule of each currently licensed Morse working frequency
and the expected use of the proposed frequencies;
(B) For additional frequencies within the same MHz band, a factual
showing of the 3 busiest hours of any 4 days within a consecutive 10 day
period for each of the 2 months immediately preceding the filing of the
application indicating that the applicant has used its currently
assigned frequencies within the same MHz band an aggregate average of at
least 40% of the 3 busiest hours of each day for exchanging
communications; and
(C) Any other facts that support the need for the proposed
assignment, e.g., evidence of radio interference by another station
located near enough to render a currently licensed frequency
substantially unusable.
(iii) The frequency 410 kHz may be used on a secondary basis for the
transmission of radiodetermination information and for transmitting by
radiotelegraph radiodetermination messages to direction-finding
stations; and
(iv) The frequency 512 kHz may be used as a supplementary calling
frequency when 500 kHz is used for distress, urgency and safety
communications. The use of the 512 kHz as a working frequency is
prohibited in areas where 500 kHz is used for distress, urgency and
safety communications.

Sec. 80.359 Frequencies for digital selective calling (DSC).
(a) General purpose calling. The following table describes the
calling frequencies for use by authorized ship and coast stations for
general purpose DSC. There are three series of paried frequencies. One
series is for worldwide use; the other two series are for regional use.
The ``Series A'' designation includes coast stations along, and ship
stations in, the Atlantic Ocean, the Gulf of Mexico, and the Caribbean
Sea. The ``Series B'' designation includes stations in any remaining
areas. Stations must initiate contact on the appropriate regional
frequency depending upon the location of the called station and
propagation conditions. Acknowledgement is made on the paired frequency.
The worldwide frequencies may be used for international calling, if
calls on the appropriate regional frequencies are unsuccessful, or the
regional series does not contain the appropriate band (e.g., 2 MHz).
During normal working hours, all public coast stations capable of DSC
operations must monitor the worldwide and regional frequencies
appropriate for its location. The specific frequencies to be monitored
will vary with propagation conditions.

kHz, 6312.0 kHz, 8414.5 kHz, 12577.0 kHz, 16804.5 kHz, and 156.525 MHz
may be used for DSC by coast and ship stations on a simplex basis for
distress and safety purposes. The provisions and procedures for distress
and safety calling are contained in CCIR Recommendation 541 as modified
by Sec. 80.103(c) of this part.
(c) Working frequencies. Coast and ship stations may use DSC
techniques for general calling purposes on their assigned working
frequencies in the 2000-27500 kHz band and on those frequencies in the
156-162 MHz band which are allocated for maritime control, commercial,
non-commercial and public correspondence communications.

(2) Applicants for these frequencies must submit a substantial
showing of need based on the following factors:
(i) A schedule of each currently licensed NBDP frequency and the
expected use of the proposed frequencies;
(ii) For additional frequencies within the same MHz band, a factual
showing of the 3 busiest hours of any 4 days within a consecutive 10 day
period for each of the 2 months immediately preceding the filing of the
application indicating that the applicant has used its currently
assigned frequencies within the same MHz band an aggregate average of at
least 40% of the 3 busiest hours of each day for exchanging
communications; and
(iii) Any other facts that support the need for the proposed
assignment, e.g., evidence of radio interference by another station
located near enough to render a currently licensed frequency
substantially unusable.
(b) Non-paired channels. The following table describes the

carrier frequency 2191 kHz may be used as a supplementary calling
frequency in areas of heavy usage of 2182 kHz. All stations must use J3E
emission when operating on 2182 and 2191 kHz, except that:
(1) H3E emission may be used on 2182 kHz for communications with
foreign coast and ship stations; or,
(2) A3E emission may be used on 2182 kHz by portable survival craft
stations, or transmitters authorized for use prior to January 1, 1972.
See Sec. 80.203(c).

(3) The following table specifies the non-paired carrier frequencies
that are available for assignment to public coast stations for simplex
operations subject to the provision of paragraph (b)(4) of this section.
These frequencies are available for use by authorized ship stations for
transmissions to coast stations (simplex operations). Assignments on
these frequencies must accept interference. They are shared with
government users and are considered ``common use'' frequencies under the
international Radio Regulations. They cannot be notified for inclusion
in the Master International Frequency Register, which provides stations
with interference protection, but may be listed in the international
List of Coast Stations. (See Radio Regulation No. 1220 and
Recommendation 304.)

\1\ Coast stations limited to a maximum transmitter power of 1 kW (PEP).
(4) Applicants for these public coast frequencies specified in this
section must submit a substantial showing of need based on the following
factors:
(i) A schedule of each currently licensed working frequency in the
4000-27500 kHz band and the expected use of the proposed frequencies;
(ii) For additional frequencies within the same MHz band, a factual
showing of the 3 busiest hours of any 4 days within a consecutive 10 day
period for each of the 2 months immediately preceding the filing of the
application indicating that the applicant has used its currently
assigned frequencies within the same MHz band an aggregate average of at
least 40% of the 3 busiest hours of each day for exchanging
communications;
(iii) Any other facts that support the need for the proposed
assignment, e.g., evidence of radio interference by another station
located near enough to render a currently licensed frequency
substantially unusable; and
(iv) For simplex frequencies listed in paragraph (b)(3) of this
section, an additional showing supporting the use of simplex rather than
duplex frequencies for the proposed situation.
(c) Working frequencies in the 156-162 MHz band. Initial grants will
be limited to one working frequency. An additional frequency may be
assigned when the assigned working frequency is also used by a foreign
station near enough to result in harmful radio interference by
simultaneous operation or when the channel occupancy of the assigned
frequency or frequencies exceeds 40 percent during its busiest hours of
operation. An application for assignment of an additional working
frequency based on channel occupancy must be accompanied by a factual
showing that for any 4 days within a 10-consecutive-day period of
station operation in each of 2 months immediately prior to the filing of
the application, the assigned frequency or frequencies was in average
daily use for exchanging communications at least 40 percent of the 3
busiest hours of each day, of which not more the half of the use time
was waiting or setup time. For purposes of this paragraph, an
application for a frequency which overlaps by 70 percent or more the
coverage area of a frequency already authorized for use by a station
licensed to the same applicant or substantially the same applicant will
be considered an application for an additional frequency.

Sec. 80.373 Private communications frequencies.
This section describes the carrier frequencies assignable for ship-
to-ship and ship-to-coast private communications.
(a) Special requirements for private coast stations. Assignment to
private coast stations of radiotelephony frequencies in the 2000-27500
kHz band are subject to the following:
(1) Private coast stations must see J3E emission.
(2) On 2182 kHz, private coast stations must be capable of receiving
J3E and H3E emissions.
(3) Except in the Mississippi River System and Great Lakes, private
coast stations serving lakes or rivers are not authorized on the 2000-
2850 kHz band.
(4) Private coast stations may use DSC for calling on their assigned
frequencies in the 2000-27500 kHz band and on those frequencies in the
156-162 MHz band which are allocated for maritime control, commercial
and non-commercial communications.
(b) Frequencies in the 2000-27500 kHz band for intership safety and
other communications. This paragraph describes the geographic areas of
operation and the frequencies and liminations in the band available for
assignment for intership safety and operational simplex radiotelephone
communications.
(1) Frequencies avaiable.

\1\ Limited to a peak envelope power of 150 watts.
\2\ Available on a secondary basis for intership communications by ships
involved in non-commercial fishing.
(2) Except for 2093.0 kHz and 2214.0 kHz the frequencies shown in
paragraph (b)(1) of this section are authorized primarily for intership
safety communications in the indicated geographic area.
(3) Except for the frequencies 2093.0 kHz, 2214.0 Khz and 2670.0 kHz
the frequencies shown in paragraph (b)(1) of this section may be used on
a non-interference basis to safety communications, for operational
communications and in the case of commercial transport ships and ships
of municipal and state governments, for business communications.
(4) Ship stations may communicate with government coast stations on
[[Page 99]]
2003.0 kHz about passage of vessels. Interference must not be caused to
communications on the St. Lawrence Seaway and on the St. Mary's River.
(5) Ship stations may use 2670.0 kHz for communications with coast
and ship stations of the U.S. Coast Guard. When a ship is not equipped
to transmit on 2670.0 kHz or in the band 156-162 MHz the frequency
2003.0 kHz may be used on the Great Lakes for communications must not
cause harmful interference to intership safety, operational and business
communications.
(6) Navigational communications between ships and private coast
stations may be exchanged on 2738.0 kHz and 2830.0 kHz. The frequencies
2214.0 kHz2738.0 kHz and 2830.0 kHz are assignable to private coast
stations upon a showing that they need to communicate with commercial
transport or Government ships. Private coast station applicants must
show that public coast stations do not provide the required
communications and harmful interference will not be caused to the
intership use of these frequencies. The transmitter power must not
exceed 150 watts. If 2214.0 kHz is authorized for ships, intership
communication is also authorized. The geographic limitations to the
frequencies 2738.0 KHz and 2830.0 Khz do not prohibit intership
communication of less than 320 km (200 statute miles) when only one of
the ship stations is within a permitted use geographic area.
(7) Private aircraft stations may communicate with ship stations on
2738.0 kHz and 2830.0 kHz if:
(i) The communications are limited to business or operational needs
of the vessel while it is engaged in commercial fishing activities in
the open sea or adjacent waters;
(ii) Harmful interference must not be caused to intership
communications;
(iii) The maximum output power used for such communication must not
exceed 25 watts;
(c) Frequencies in the 2000-27500 kHz bands for business and
operational communications. (1) The following simplex frequencies in the
2000-27500 kHz band are available for assignment to private coast
stations for business and operational radiotelephone communications.
These simplex frequencies also are available for use by authorized ship
stations for business and operational radiotelephone communications.
