§ 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).
