Sec. 74.534  Power limitations.

    (a) for operation in the 944-952 MHz band:
    Aural broadcast STL and intercity relay stations will be licensed 
with a power output not in excess of that necessary to render 
satisfactory service. The license for these stations will specify the 
maximum authorized power. The operating power shall not be greater than 
necessary to carry on the service and in no event more than 5 percent 
above the maximum power specified. Engineering standards have not been 
established for these stations. The efficiency factor for the last radio 
stage of transmitters employed will be subject to individual 
determination but shall be in general agreement with values normally 
employed for similar equipment operated within the frequency range 
authorized.
    (b) For stations operating in bands above 17.7 GHz, the transmitter 
output power shall be limited to that necessary to accomplish the 
function of the system. Further, the output power of a transmitter on 
any authorized frequency shall not exceed the following:
