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.
