Sec.  23.18   Authorization of power.

   (a) Authorized power. Power, when designated in the respective station
   license for a particular transmitter or transmitters, is peak envelope power
   for transmitters having full, unkeyed carrier, single sideband or
   independent sideband emissions, and mean power for transmitters having other
   emissions, unless specifically expressed otherwise. Designation of effective
   radiated power may appear in the station license in addition to designation
   of power for a transmitter or transmitters, when deemed necessary by the
   Commission.

   (b) Use of minimum power. In the interest of avoiding interference to other
   operations, all stations shall radiate only as much power as is necessary to
   ensure a satisfactory service.
