Sec.  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.

\1\ The power delivered to the antenna is limited to -3 dBW.
\2\ Stations 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.
