Sec. 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.
