Sec.  74.636   Power limitations.

   (a) On any authorized frequency, transmitter peak output power and the
   average power delivered to an antenna in this service must be the minimum
   amount of power necessary to carry out the communications desired and shall
   not exceed the values listed in the following table. Application of this
   principle includes, but is not to be limited to, requiring a licensee who
   replaces one or more of its antennas with larger antennas to reduce its
   antenna input power by an amount appropriate to compensate for the increased
   primary lobe gain of the replacement antenna(s). In no event shall the
   average equivalent isotropically radiated power (EIRP), as referenced to an
   isotropic radiator, exceed the values specified in the following table. In
   cases of harmful interference, the Commission may, after notice and
   opportunity for hearing, order a change in the effective radiated power of
   this station. The table follows:

------------------------------------------------------------------------
\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) 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.
