§ 73.1670 Auxiliary transmitters.
(a) A licensee of a broadcast station may, without further authority from
the FCC, install and use with the main antenna system one or more auxiliary
transmitters for the following purposes:
(1) The transmission of regular programs upon failure of the main
transmitter.
(2) The transmission of regular programs during maintenance or modification
of the main transmitter.
(3) Emergency broadcast system operation.
(4) The transmission of regular programs by an AM station authorized for
Presunrise (PSRA) and/or Postsunset (PSSA) operation.
(5) The transmission of tests to determine the operating condition of the
auxiliary transmitter or auxiliary antenna.
(6) For testing, upon the request of representatives of the FCC.
(b) Authorization to install an auxiliary transmitter for use with other
than the main antenna or authorized auxiliary antenna must be obtained by
filing an application for a construction permit on FCC form 301 (FCC form
340 for noncommercial educational stations).
(c) The following technical and operating standards apply to auxiliary
transmitters:
(1) The auxiliary transmitter may be operated on only the station's
authorized frequency and within the required carrier frequency departure
tolerance for the type of station.
(2) The carrier frequency of the auxiliary transmitter must be measured as
often as necessary to ensure that it is maintained within the prescribed
tolerance.
(3) When using an auxiliary transmitter, the operating power may be less
than the authorized power but may not exceed the authorized power within the
permitted tolerance for the type of station. If operation with an auxiliary
transmitter at reduced power continues for a period exceeding 10 days, the
FCC in Washington, DC must be notified. (See § 73.51, AM; § 73.267, FM;

existing licenses be renewed for auxiliary transmitters that are operated
into the main antenna system.
