Paperwork Reduction Act
The R&O contains new or modified information collection
requirements subject to the Paperwork Reduction Act of 1995 (PRA),
Public Law 104-13, see 44 U.S.C. 3507. The Commission, as part of its
continuing effort to reduce paperwork burdens, will invite the general
public and the Office of Management and Budget (OMB) to comment on the
information collection requirements contained in this document in a
separate Federal Register Notice, as required by the PRA. These new or
modified information collections will become effective after the
Commission publishes a document in the Federal Register announcing such
approval and the relevant effective date.
In addition, pursuant to the Small Business Paperwork Relief Act of
2002, Public Law 107-198, see 44 U.S.C. 3506(c)(4), the Commission
previously sought specific comment on how the Commission might further
reduce the information collection burden for small business concerns
with fewer than 25 employees.
Congressional Review Act
The Commission will send a copy of the R&O to Congress and the
Government Accountability Office (GAO) pursuant to the Congressional
Review Act, 5 U.S.C. 801(a)(1)(A).
Synopsis
1. Introduction. In this R&O, the Commission adopts rules regarding
all-digital AM broadcasting that it proposed in a notice of proposed
rulemaking, FCC 19-123, 34 FCC Rcd 11560 (2019), 85 FR 649 (Jan. 7,
2020) (NPRM). These rules allow AM stations, on a voluntary basis, to
cease broadcasting an analog signal and broadcast using only an all-
digital signal in the HD Radio MA3 mode. This measure will benefit AM
stations and their listeners by improving reception quality and
listenable coverage in stations' service areas and will advance the
Commission's goal of improving and modernizing the AM radio service.
Currently, the AM broadcasting service suffers from interference and
reception issues caused in part by increased emissions from various
consumer electronic devices as well as broadcast sources. As a result,
many AM stations are constrained to low-fidelity voice formats such as
talk radio. Under the current rules, AM and FM stations are permitted
to broadcast using either an analog signal or the hybrid analog and
digital system licensed by Xperi Corporation under the brand name HD
Radio. In the United States, the only technology for digital
broadcasting in the AM and FM bands approved by the Commission is the
HD Radio IBOC system. Although many FM stations have converted to
hybrid broadcasting, various technical and other issues have prevented
the widespread adoption of hybrid broadcasting by AM stations.
2. Testing and experimental broadcasting indicate that all-digital
AM transmission has the potential to improve signal ``robustness''--or
resistance to interference and other impairments--as well as the
ability to transmit auxiliary information to accompany the main audio
programming. This robustness will result in a clearer signal for
listeners and a greater area of listenable coverage compared to an
analog signal. All-digital broadcasting will increase the format
choices that AM broadcasters can offer to their audiences, including
the option of music programming. Digital operation also eliminates the
tradeoff between receiver audio bandwidth and noise performance. In
addition, digital broadcasting allows visual and other metadata, such
as song and artist identification, station identification, and
emergency information, to be transmitted along with the audio content.
Such auxiliary information is increasingly expected by consumers and
considered to be a vital component of modern broadcasting. Finally,
all-digital broadcasting will result in energy and spectrum
efficiencies, because it provides additional and/or improved services
over the same allocated frequencies.
3. The Commission anticipates that potential loss of service to
analog-only listeners will be mitigated by the gradual, voluntary
nature of the transition, the financial interest of radio stations in
reaching a wide audience, duplicate programming provided by co-owned AM
stations, and analog broadcasts on FM translators affiliated with all-
digital AM stations.
4. The Commission finds that a sufficient number of digital
receivers are currently in use to support a voluntary option to convert
to all-digital. Moreover, as the number of digital receivers increases,
more markets will be able to support all-digital broadcasting.
Similarly, the cost of conversion is not an impediment to providing a
voluntary option to convert, because stations can make their own
decisions whether to pursue all-digital operations based on their own
financial and technical situation as well as the needs and interests of
their audience and the number of digital receivers in their market. The
Commission notes that at the time of adoption, Xperi has stated that it
will waive licensing fees for AM stations that choose to go all-
digital.
5. Operating and technical rules. In the R&O, the Commission
establishes that the power limits for all-digital stations must be
calculated using the average power of the all-digital signal, including
the unmodulated analog carrier and all of the digital sidebands, to
determine whether the station complies with the nominal power limits
set out in Sec. 73.21 of the Commission's rules. Using the average
power to calculate compliance with the nominal power limit will enable
more stations to use existing transmitters for all-digital operations,
thus reducing the cost of upgrading to all-digital and allowing more
stations to convert. In addition, this method of calculating nominal
power will result in a lower operating power for all-digital stations,
which will be less likely to cause interference with analog signals
while still maintaining improved listenable coverage areas.
6. The Commission applies the emissions mask set out in Sec. 73.44
of the Commission's rules to all-digital operations. This emissions
mask attenuates--or limits--spectral emissions outside a bandwidth of
20 kHz to the point where they do not cause significant adjacent
channel interference. The Commission concludes that these emissions
limits will adequately protect stations on adjacent channels from all-
digital interference. It declines to impose the stricter emissions
limits set out in the HD Radio specifications, which may not be set at
technically feasible levels and may need to be revisited in light of
field data from all-digital experimental operation. Although testing
indicates that the digital signals may cause some increased degradation
to analog signals, in most cases this will be masked by the noise
floor, and in any case there is no evidence that interference will
occur within service areas that are currently protected under our
rules.
7. Recognizing that digital power measurement is an evolving and
highly technical area, the Commission provides all-digital licensees
the flexibility to choose any reliable and reasonably accurate method
to measure their compliance with the Commission' operating power and
power spectral density rules, including measurement tools integrated
into digital transmitters, thermocouple RF ammeters, or averaging the
power spectral density in a 300-Hz bandwidth over a minimum time span
of 30 seconds and a minimum of 100 sweeps.
8. Each all-digital station is obligated to provide at least one
free over-the-air
[[Page 78024]]
digital programming stream that is comparable to or better in audio
quality than a standard analog broadcast. Beyond this requirement, an
all-digital licensee can use its additional digital bitrate capacity
for either broadcast or non-broadcast services consistent with the
Commission's technical rules. The Commission permits each AM
broadcaster to select either core-only or enhanced mode transmission as
their situation dictates.
9. The Commission imposes the same carrier frequency tolerance
applicable to analog and hybrid stations (20 Hz) on all-
digital AM stations. It declines to impose a 1 Hz AM
carrier frequency tolerance standard on all AM stations as proposed in
the NPRM, on the basis that the benefit to audio reception of doing so
would not outweigh the burden on already struggling AM stations. The
Commission also declines to incorporate by reference the National Radio
Systems Committee's NRSC-5-D standard governing all-digital
transmission into the Commission's rules, as proposed in the NPRM,
finding that there is no need to do so and that--as a voluntary
industry standard--the standard can be more readily updated in response
to technological developments or operational feedback from all-digital
stations.
10. The Commission prohibits all-digital stations from causing
interference as currently defined in the rules. Although testing
indicates that the potential for co-channel interference is higher for
all-digital than for analog, the Commission concludes that neither
adjacent- or co-channel interference as defined in the rules is likely
to occur. The potential for additional co-channel interference is
mitigated in the presence of a high level of environmental noise, in
which case the all-digital interference is likely to be subsumed by the
overall noise floor, masking the interfering effect of the all-digital
signal. However, if prohibited interference occurs, the Commission
establishes a remediation procedure based on the procedures currently
applicable to hybrid stations. Specifically, the Commission expects AM
all-digital operators and complaining stations to work together to
identify whether interference exists and to resolve it in a mutually
acceptable fashion, including voluntary power reduction.
11. The new rules permit up to 6 dB power reduction, without prior
approval, in the all-digital secondary or tertiary sidebands (but not
the primary digital sidebands) to avoid or resolve prohibited
interference. The Commission expects that the gradual nature of the
transition will enable it to resolve any immediate issues using
existing rules and the remediation procedure. Both daytime and
nighttime all-digital AM operation are permitted, and any prohibited
interference resulting from nighttime skywave transmissions must be
promptly resolved. Finding that the record demonstrates the technical
feasibility of all-digital broadcasting, the Commission concludes that
it is not in the public interest to delay implementation by requiring
additional tests or require that stations undertake potentially
expensive digital conversions under experimental licenses.
12. All all-digital AM stations, like other broadcast stations,
must participate in the nationwide Emergency Alert System (EAS). This
obligation extends to ensuring that any ``downstream'' EAS participant
stations are capable of receiving and decoding EAS alerts from the all-
digital station or can adjust their monitoring assignments to receive
EAS alerts from another nearby station. The Commission concludes that
listeners will have sufficient access to EAS alerts without mandating
that EAS alerts be transmitted using analog signals. In addition, all-
digital stations can transmit useful emergency information to listeners
other than on the main audio stream, including, for example, text in
multiple languages or images such as missing persons or evacuation
routes.
13. The Commission adopts a modified version of the current digital
notification procedure for all-digital stations by adding a 30-day
waiting period for certain operational changes. Specifically, it
requires licensees to electronically file a digital notification, using
the existing FCC Form 335-AM Digital Notification (or any successor
notification), to notify the Commission of the following changes: (1)
The commencement of new all-digital operation; (2) an increase in
nominal power of an all-digital AM station; or (3) a transition from
core-only to enhanced operating mode. All-digital AM notifications will
be placed on a Commission public notice, and new operation may begin no
sooner than 30 calendar days from the date of this public notice. This
will minimize the paperwork required for all-digital AM conversions
while giving local co-channel and adjacent channel stations time to
gather baseline data on their existing coverage before the new all-
digital operation begins. Digital notification must be submitted within
ten days of implementing all other changes, namely: (1) Any reduction
in nominal power of an all-digital AM station; (2) a transition from
enhanced to core-only operating mode; or (3) a reversion from all-
digital to hybrid or analog operation.
14. Although the Commission directs broadcasters to use the current
Form 335-AM for all-digital notifications, additional information is
required for notification of all-digital operations specifically.
Therefore, until the Form 335-AM is updated to display all-digital
operation requirements, the Commission directs filers to select ``N/A''
as appropriate within the form and submit an attachment with the Form
335-AM containing the following information: (1) The type of
notification (all-digital notification, increase in nominal power,
reduction in nominal power, transition from core-only to enhanced,
transition from enhanced to core-only, reversion from all-digital to
hybrid or analog operation); (2) the date that new or modified all-
digital operation will commence or has ceased; (3) a certification that
the all-digital operations will conform to the relevant nominal power
and spectral emissions limits; (4) the nominal power of the all-digital
station; (5) a certification that the all-digital station complies with
all EAS requirements; and (6) if a notification of commencement of new
all-digital service or a nominal power change, whether the station is
operating in core-only or enhanced mode.
15. During the 30-day period established above, the Commission
requires that an AM broadcaster commencing new all-digital operation
must provide reasonable notice to its listeners that the station will
be converting to all-digital operation and will no longer be available
on analog receivers. Because broadcasters have a strong incentive to
promote such a change to their listeners, the Commission gives them
flexibility to use reasonable methods intended to reach their audience,
including on-air and website announcements. However, in the event that
the reasonableness of notice of conversion to all-digital operation is
challenged, the Commission would consider it presumptively sufficient
if the broadcaster provided at least the same amount of notice as that
set out in Sec. 73.3580, the local public notice rule, with which
broadcasters are already familiar.
16. The Commission declined to consider alternative technologies to
HD Radio, such as Digital Radio Mondiale, finding that in the absence
of any data regarding DRM performance in the U.S. AM band, it cannot
evaluate its merits. Because it is in the public interest to provide an
immediate path forward for
[[Page 78025]]
AM stations to broadcast in all-digital as their circumstances allow,
the Commission approves the HD Radio MA3 mode as the only currently
feasible technology option before it, but does not foreclose the future
consideration of alternative transmission technologies.
Procedural Matters
17. Final Regulatory Flexibility Analysis. As required by the
Regulatory Flexibility Act of 1980, as amended (RFA), an Initial
Regulatory Flexibility Analysis (IRFA) was incorporated into the NPRM
in this proceeding. The Commission sought written public comment on the
proposals in the NPRM, including comment on the IRFA. Because the
Commission amended the rules in this Report and Order (R&O), it
included this Final Regulatory Flexibility Analysis (FRFA), which
conforms to the RFA.
18. Need for, and Objectives of, the R&O. The R&O adopts several
rule changes to allow AM stations to voluntarily broadcast an all-
digital signal using the digital broadcasting technology known as HD
Radio MA3. This action will improve the AM radio service by providing
enhanced audio quality, increasing listenable reception areas, and
allowing additional metadata textual information, such as song and
artist identification, traffic services, and digital emergency alerts,
to be transmitted along with the main audio programming. All-digital
operation will increase the format choices that AM broadcasters can
offer to their audiences, including the option of music programming.
These greater capabilities will level the playing field between AM and
FM signals from the listener's perspective, and help AM stations
recapture audiences lost to FM radio, satellite radio, or online
streaming services because of their higher sound fidelity and broader
programming array. All-digital AM operation will also provide the full
technological benefits of digital broadcasting while avoiding the
shortcomings of the current analog or hybrid modes of transmission,
which are more susceptible to noise and interference, more likely to
cause interference to other stations, and place more demands on an AM
station's transmission and antenna system.
19. All-digital operation provides greater usable signal coverage,
is energy- and spectrum-efficient, and will be supported by an ever-
increasing number of digital receivers. Since all-digital operation is
completely voluntary, and the cost of conversion will vary from station
to station, AM broadcasters will be able to decide whether conversion
to all-digital meets their own needs and market demand. In the R&O, the
Commission concludes that the public interest in the long-term
viability of AM stations and the valuable services they provide,
outweighs a possible loss of service to some current analog listeners
as broadcasters and the listening public transition to an all-digital
environment. All-digital service represents a significant and singular
opportunity to preserve the AM service for future listeners. Any
disruption to analog listeners will take place gradually, as AM
stations individually decide their audience is ready to convert to all-
digital, with full notice to consumers and ample opportunity to adjust
to the new technology.
20. In the R&O, the Commission authorizes all-digital operations
subject to the requirement that all-digital operations not cause
prohibited interference to existing broadcast stations. In the unlikely
event that such interference would occur, the Commission will apply
current remediation procedures that encourage cooperation between the
parties to resolve complaints and include an option to voluntarily
reduce power. The Commission adopts the proposal in the NPRM that each
all-digital station is obligated to provide at least one free over-the-
air digital programming stream that is comparable to or better in audio
quality than a standard analog broadcast. It also mandates that all-
digital AM stations participate in the national Emergency Alert System
(EAS).
21. Although all-digital conversion is a purely voluntary process
for individual AM stations, the Commission strongly supports an all-
digital future and affirms that the objective of the proceeding is a
viable all-digital AM service. Supporting all-digital removes any
regulatory uncertainty about the future of the AM HD Radio system and
should give car companies and receiver manufacturers reassurance to
invest in AM digital receivers. Thus, an all-digital environment will
reduce the likelihood of interference while maximizing digital benefits
such as an improved high-quality listener experience, signal
robustness, reliable and listenable coverage, and superior audio
quality.
22. Summary of Significant Issues Raised by Public Comments in
Response to the IRFA. There were no comments to the IRFA filed.
23. Response to Comments by the Chief Counsel for Advocacy of the
Small Business Administration. Pursuant to the Small Business Jobs Act
of 2010, which amended the RFA, the Commission is required to respond
to any comments filed by the Chief Counsel for Advocacy of the Small
Business Administration (SBA), and to provide a detailed statement of
any change made to the proposed rules as a result of those comments. 5
U.S.C. 604(a)(3). The Chief Counsel did not file any comments in
response to the proposed rules in this proceeding.
24. Description and Estimate of the Number of Small Entities to
Which the Proposed Rules Will Apply. The RFA directs the Commission to
provide a description of and, where feasible, an estimate of the number
of small entities that will be affected by the rules adopted herein.
The RFA generally defines the term ``small entity'' as having the same
meaning as the terms ``small business,'' ``small organization,'' and
``small government jurisdiction.'' In addition, the term ``small
business'' has the same meaning as the term ``small business concern''
under the Small Business Act. A small business concern is one which:
(1) Is independently owned and operated; (2) is not dominant in its
field of operation; and (3) satisfies any additional criteria
established by the Small Business Administration (SBA).
25. Radio Stations. Radio stations are an Economic Census category
that ``comprises establishments primarily engaged in broadcasting aural
programs by radio to the public. Programming may originate in their own
studio, from an affiliated network, or from external sources.'' The SBA
has established a small business size standard for this category as
firms having $41.5 million or less in annual receipts. Economic Census
data for 2012 shows that 2,849 radio station firms operated during that
year. Of that number, 2,806 operated with annual receipts of less than
$25 million per year, and 43 firms had annual receipts of $25 million
or more. Because the Census has no additional classifications that
could serve as a basis for determining the number of stations whose
receipts exceeded $41.5 million in that year, the Commission concludes
that the majority of radio broadcast stations were small entities under
the applicable SBA size standard.
26. Apart from the U.S. Census, the Commission has estimated the
number of licensed commercial AM stations to be 4,570 and the number of
commercial FM stations to be 6,706 for a total of 11,276, along with
8,303 FM translator and booster stations. According to BIA/Kelsey
Publications, Inc.'s Media Access Pro Database, as of March 2020, 4,389
AM stations and 6,767 FM stations had revenues of $41.5 million or
less. In addition, the Commission has estimated the number of
noncommercial educational FM radio stations to be
[[Page 78026]]
4,197. NCE stations are non-profit, and therefore considered to be
small entities. Accordingly, the Commission estimates that the majority
of radio broadcast stations are small entities. The Commission notes,
however, that, in assessing whether a business concern qualifies as
small under the above definition, business (control) affiliations must
be included. Our estimate, therefore, likely overstates the number of
small entities that might be affected by our action, because the
revenue figure on which it is based does not include or aggregate
revenues from affiliated companies.
27. Moreover, as noted above, an element of the definition of
``small business'' is that the entity not be dominant in its field of
operation. The Commission is unable at this time to define or quantify
the criteria that would establish whether a specific radio station is
dominant in its field of operation. Accordingly, the estimate of small
businesses to which rules may apply does not exclude any radio station
from the definition of a small business on this basis and therefore may
be over-inclusive to that extent. Also, as noted, an additional element
of the definition of ``small business'' is that the entity must be
independently owned and operated. The Commission notes that it is
difficult at times to assess these criteria in the context of media
entities and the estimates of small businesses to which they apply may
be over-inclusive to this extent.
28. Description of Projected Reporting, Recordkeeping, and Other
Compliance Requirements. The rules changes adopted in the R&O establish
a straightforward procedure for stations to notify the Commission of a
change to all-digital operations. The notification requirement for all-
digital operations, is as follows: AM licensees must electronically
file a digital notification, using the existing FCC Form 335-AM Digital
Notification (or any successor notification form), to notify the
Commission of the following proposed changes: (1) The commencement of
new all-digital operation; (2) an increase in nominal power of an all-
digital AM station; or (3) a transition from core-only to enhanced
operating mode. All-digital AM notifications will be placed on an FCC
public notice, and new operation may begin no sooner than 30 calendar
days from the date of this public notice. This notification process
will minimize the paperwork required for all-digital AM conversions,
while giving local co-channel and adjacent channel stations time to
gather baseline data on their existing coverage before the new all-
digital operation begins. Digital notification must be submitted within
ten days of implementing all other changes, namely: (1) Any reduction
in nominal power of an all-digital AM station; (2) a transition from
enhanced to core-only operating mode; or (3) a reversion from all-
digital to hybrid or analog operation. There is no fee for filing a
digital notification.
29. The R&O does not adopt recordkeeping requirements. However, it
does require licensees converting AM stations to all-digital operation
to provide reasonable notice to its listeners that their station will
be converting to all-digital operations and will no longer be available
on analog receivers.
30. Steps Taken to Minimize Significant Impact on Small Entities
and Significant Alternatives Considered. The RFA requires an agency to
describe any significant alternatives that it has considered in
reaching its proposed approach, which may include the following four
alternatives (among others): (1) The establishment of differing
compliance or reporting requirements or timetables that take into
account the resources available to small entities; (2) the
clarification, consolidation, or simplification of compliance or
reporting requirements under the rule for small entities; (3) the use
of performance, rather than design, standards; and (4) an exemption
from coverage of the rule, or any part thereof, for small entities.
31. Conversion to all-digital AM transmission (and then, consequent
compliance with the rules governing all-digital operation) is
completely voluntary and therefore flexible, based on an AM
broadcaster's assessment of its individual financial and technical
circumstances, including size. AM broadcasters overwhelmingly support
the proposal to allow all-digital AM broadcasting, as do broadcast
engineers, technology companies, and individual listeners. Of the
technical requirements contemplated in the NPRM, the Commission
evaluated several alternative options. The Commission originally
considered imposing a (non-voluntary) stricter frequency tolerance
standard of 1 Hz on all AM broadcasters, but decided that the benefits
of doing so would not outweigh the associated burden of upgrading
transmission equipment, particularly for smaller AM broadcasters, and
declined to adopt the requirement. In addition, the Commission
considered incorporating the NRSC-5-D Standard governing the technical
implementation of HD Radio all-digital radio into the rules, but upon
careful consideration of the record, decided that doing so would be
unnecessary and could stifle industry innovation regarding the all-
digital HD Radio technology. Therefore, in reaching the approach taken
in the R&O, the Commission considered various alternatives and their
effects on AM broadcasters, including small entities.
32. Report to Congress. The Commission will send a copy of the R&O
to Congress and the Government Accountability Office pursuant to the
Congressional Review Act. In addition, the Commission will send a copy
of the document, including this FRFA, to the Chief Counsel for Advocacy
of the SBA. A copy of the document and FRFA (or summaries thereof) will
also be published in the Federal Register.
33. Paperwork Reduction Act. This R&O contains new or modified
information collection requirements subject to the Paperwork Reduction
Act of 1995 (PRA), Public Law 104-13. The requirements will be
submitted to the Office of Management and Budget (OMB) for review under
section 3507(d) of the PRA. OMB, the general public, and other Federal
agencies are invited to comment on the new or modified information
collection requirements contained in this proceeding. In addition, the
Commission notes that pursuant to the Small Business Paperwork Relief
Act of 2002, Public Law 107-198, see 44 U.S.C. 3506(c)(4), it
previously sought specific comment on how the Commission might further
reduce the information collection burden for small business concerns
with fewer than 25 employees.
34. Congressional Review Act. The Commission has determined, and
the Administrator of the Office of Information and Regulatory Affairs,
Office of Management and Budget, concurs, that these rules are ``non-
major'' under the Congressional Review Act, 5 U.S.C. 804(2). The
Commission will send a copy of this R&O to Congress and the Government
Accountability Office pursuant to the Congressional Review Act.

(a) The licensee of an AM or FM station, or the permittee of a new
AM or FM station which has commenced program test operation pursuant to
Sec. 73.1620, may commence hybrid IBOC DAB operation with digital
facilities which conform to the technical specifications specified for
hybrid DAB operation in the (2002) First Report and Order in MM Docket
No. 99-325, as revised in the Media Bureau's subsequent Order in MM
Docket No. 99-325. In addition, the licensee of an AM station, or the
permittee of a new AM station that has commenced program test authority
pursuant to Sec. 73.1620, may, with reasonable notice to listeners,
commence all-digital IBOC operation with digital facilities that
conform to the requirements set out in the (2020) Report and Order in
MB Docket No. 19-311 and MB Docket No. 13-249. An AM or FM station may
transmit IBOC signals during all hours for which the station is
licensed to broadcast.
(b) In situations where interference to other stations is
anticipated or actually occurs, hybrid AM licensees may, upon
notification to the Commission, reduce the power of the primary DAB
sidebands by up to 6 dB. All-digital AM licensees, may, upon
notification to the Commission, reduce the power of the secondary and
tertiary sidebands by up to 6 dB, even if doing so results in non-
compliance with Sec. 73.1560(a)(1). Any greater reduction of sideband
power requires prior authority from the Commission via the filing of a
request for special temporary authority or an informal letter request
for modification of license.

5. Add Sec. 73.406 to read as follows:
Sec. 73.406 Notification.
(a) Hybrid AM and FM licensees must electronically file a digital
notification to the Commission in Washington, DC, within 10 days of
commencing IBOC digital operation.
(1) All-digital licensees must file a digital notification within
10 days of the following changes:
(i) Any reduction in nominal power of an all-digital AM station;
(ii) A transition from enhanced to core-only operating mode; or
(iii) A reversion from all-digital to hybrid or analog operation.
(2) All-digital licensees will not be permitted to commence
operation sooner than 30 calendar days from public notice of digital
notification of the following changes:
(i) The commencement of new all-digital operation;
(ii) An increase in nominal power of an all-digital AM station; or
(iii) A transition from core-only to enhanced operating mode.
(b) Every digital notification must include the following
information:
(1) The call sign and facility identification number of the
station;
(2) If applicable, the date on which the new or modified IBOC
operation commenced or ceased;
(3) The name and telephone number of a technical representative the
Commission can call in the event of interference;
(4) A certification that the operation will not cause human
exposure to levels of radio frequency radiation in excess of the limits
specified in Sec. 1.1310 of this chapter and is therefore
categorically excluded from environmental processing pursuant to Sec.
1.1306(b) of this chapter. Any station that cannot certify compliance
must submit an environmental assessment (``EA'') pursuant to Sec.
1.1311 of this chapter and may not commence IBOC operation until such
EA is ruled upon by the Commission.
(c) Each AM digital notification must also include the following
information:
(1) A certification that the IBOC DAB facilities conform to
applicable nominal power limits and emissions mask limits;
(2) The nominal power of the station; if separate analog and
digital transmitters are used, the nominal power for each transmitter;
(3) If applicable, the amount of any reduction in an AM station's
digital carriers;
(4) For all-digital stations, the type of notification (all-digital
notification, increase in nominal power, reduction in nominal power,
transition from core-only to enhanced, transition from enhanced to
core-only, reversion from all-digital to hybrid or analog operation);
(5) For all-digital stations, if a notification of commencement of
new all-digital service or a nominal power change, whether the station
is operating in core-only or enhanced mode; and
(6) For all-digital stations, a certification that the all-digital
station complies with all Emergency Alert System (EAS) requirements in
part 11 of this chapter.
(d) Each FM digital notification must also include the following
information:
[[Page 78028]]
(1) A certification that the IBOC DAB facilities conform to the HD
Radio emissions mask limits;
(2) FM digital effective radiated power used and certification that
the FM analog effective radiated power remains as authorized;
(3) If applicable, the geographic coordinates, elevation data, and
license file number of the auxiliary antenna employed by an FM station
as a separate digital antenna; and
(4) If applicable, for FM systems employing interleaved antenna
bays, a certification that adequate filtering and/or isolation
equipment has been installed to prevent spurious emissions in excess of
the limits specified in Sec. 73.317.
