Sec. 74.531 Permissible service.
(a) An aural broadcast STL station is authorized to transmit aural program
material between the studio and transmitter location of a broadcasting
station, except an international broadcasting station, for simultaneous or
delayed broadcast.
(b) An aural broadcast intercity relay station is authorized to transmit
aural program material between broadcasting stations, except international
broadcasting stations, for simultaneous or delayed broadcast.
(c) An aural broadcast intercity relay station is authorized to transmit
aural program material between noncommercial educational FM radio stations
and their co-owned noncommercial educational FM translator stations assigned
to reserved channels (Channels 201 to 220) and between FM radio stations and
FM translator stations operating within the coverage contour of their
primary stations. This use shall not interfere with or otherwise preclude
use of these broadcast auxiliary facilities by broadcast auxiliary stations
transmitting aural programming between broadcast stations as provided in
paragraph (b) of this section.
(d) An aural broadcast STL or intercity relay may be used to transmit
material between an FM broadcast radio station and an FM booster station
owned, operated, and controlled by the licensee of the originating FM radio
station. This use shall not interfere with or otherwise preclude use of
these broadcast auxiliary facilities by broadcast auxiliary stations
transmitting aural programming between the studio and transmitter location
of a broadcast station or between broadcast stations as provided in
paragraphs (a) and (b) of this section.
(e) An aural broadcast microwave booster station is authorized to retransmit
the signals of an aural broadcast STL or intercity relay station.
(f) Multiplexing of the STL or intercity relay transmitter may be employed
to provide additional communication channels for the transmission of aural
program material, news-wire teleprinter signals relaying news to be
associated with main channel programming, operational communications, and
material authorized to be transmitted over an FM station under a valid
Subsidiary Communications Authorization (SCA). An aural broadcast STL or
intercity relay station may not be operated solely for the transmission of
operational, teleprinter or subsidiary communications. Operational
communications include cues, orders, and other communications directly
related to the operation of the broadcast station as well as special signals
used for telemetry or the control of apparatus used in conjunction with the
broadcasting operations.
(g) All program material, including subsidiary communications, transmitted
over an aural broadcast STL or intercity relay station shall be intended for
use by broadcast stations owned or under common control of the licensee or
licensees of the STL or intercity relay station. Other broadcast stations
may simultaneously utilize such program material with permission of the STL
or intercity relay station licensee.
(h) In any case where multiplexing, is employed on an aural broadcast STL
station for the simultaneous transmission of more than one aural channel,
the STL transmitter must be capable of transmitting the multiple channels
within the channel on which the STL station is authorized to operate and
with adequate technical quality so that each broadcast station utilizing the
circuit can meet the technical performance standards stipulated in the rules
governing that class of broadcasting station. If multiplex operation is
employed during the regular operation of the STL station, the additional
circuits shall be in operation at the time that the required periodic
performance measurements are made of the overall broadcasting system from
the studio microphone input circuit to the broadcast transmitter output
circuit.
