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:
   Frequency band (MHz) Maximum allowable transmitter power Maximum allowable
   EIRP^2
   Mobile (W) Fixed (dBW) Mobile (dBW)
   2,025 to 2,110 12.0 +45 +35
   2,450 to 2,483.5 12.0 +45 +35
   6,425 to 6,525 12.0 +35
   6,875 to 7,125 12.0 +55 +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) 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.
