§ 78.101   Power limitations.

   (a) On any authorized frequency, the average power delivered to an antenna
   shall  be  the  minimum  amount  of  power  necessary to carry out the
   communications desired. In no event shall the average transmitter power or
   equivalent isotropically radiated power (EIRP) exceed the values specified
   below.
   Frequency band
   (MHz) Maximum allowable transmitter power—mobile (W) Maximum allowable
   EIRP^1 2
   Fixed (dBW) Mobile (dBW)
   2,025 to 2,110 20.0 + 35
   6,425 to 6,525 20.0 + 35
   6,875 to 7,125 20.0 + 35
   12,700 to 13,250 1.5 + 55 + 45
   17,700 to 18,600 + 55
   18,600 to 18,800^1 + 35
   18,800 to 19,700 + 55

   ^1The power delivered to the antenna is limited to −3 dBW.

   ^2Stations licensed based on an application filed before April 16, 2003, for
   EIRP  values  exceeding those specified above, may continue to operate
   indefinitely in accordance with the terms of their current authorizations,
   subject to periodic renewal.

   (b) LDS stations shall use for the visual signal-vestigial sideband AM
   transmission. When vestigial sideband AM transmission is used the peak power
   of the visual signal on all channels shall be maintained within 2 dB of
   equality. The mean power of the aural signal on each channel shall not
   exceed a level of 7 dB below the peak power of the visual signal.

   (c) The EIRP of transmitters that use Automatic Transmitter Power Control
   (ATPC) shall not exceed the EIRP specified on the station authorization. The
   EIRP of non-ATPC transmitters shall be maintained as near as practicable to
   the EIRP specified on the station authorization.
