§  80.959   Radiotelephone transmitter.

   (a) The transmitter must be capable of transmission of G3E emission on
   the required frequencies.

   (b) The transmitter must deliver a carrier power of between 10 watts
   and 25 watts into 50 ohms nominal resistance when operated with its
   rated supply voltage. The transmitter must be capable of readily
   reducing the carrier power to one watt or less.

   (c) To demonstrate the capability of the transmitter, measurements of
   primary supply voltage and transmitter output power must be made with
   the equipment operating on the vessel's main power supply, as follows:

   (1) The primary supply voltage measured at the power input terminals to
   the transmitter terminated in a matching artificial load, must be
   measured at the end of 10 minutes of continuous operation of the
   transmitter at its rated power output.

   (2) The primary supply voltage, measured in accordance with the
   procedures of this paragraph, must be not less than 11.5 volts.

   (3) The transmitter at full output power measured in accordance with
   the procedure of this paragraph must not be less than 10 watts.
