  §  74.534   Power limitations.

   (a) Transmitter output power. (1) Transmitter output power shall be
   limited to that necessary to accomplish the function of the system.

   (2) In the 17,700 to 19,700 MHz band, transmitter output power shall
   not exceed 10 watts.

   (b) 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 equivalent isotropically radiated power of this station.
   Frequency band (MHz) Maximum Allowable^1 EIRP (dBW)
   944 to 952           + 40
   17,700 to 18,600     + 55
   18,600 to 19,700     + 35

   ^1Stations 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.

   (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.
