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.
