(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 § 1.1310 of this chapter and is therefore categorically excluded from
environmental processing pursuant to § 1.1306(b) of this chapter. Any
station that cannot certify compliance must submit an environmental
assessment (“EA”) pursuant to § 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:
(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 § 73.317.
