Sec. 87.91  Operation of transmitter controls.

    The holder of a marine radio operator permit or a restricted 
radiotelephone operator permit must perform only transmitter operations 
which are controlled by external switches. These operators must not 
perform any internal adjustment of transmitter frequency determining 
elements. Further, the stability of the transmitter frequencies at a 
station operated by these operators must be maintained by the 
transmitter itself. When using an aircraft radio station on maritime 
mobile service frequencies the carrier power of the transmitter must not 
exceed 250 watts (emission A3E) or 1000 watts (emission R3E, H3E, or 
J3E).
