Sec. 80.855  Radiotelephone transmitter.

    (a) The transmitter must be capable of transmission of H3E and J3E 
emission on 2182 kHz, and J3E emission on 2638 kHz and at least two 
other frequencies within the band 1605 to 3500 kHz available for ship-
to-shore or ship-to-ship communication.
    (b) The duty cycle of the transmitter must permit transmission of 
the international radiotelephone alarm signal.
    (c) The transmitter must be capable of transmitting clearly 
perceptible signals from ship to ship during daytime under normal 
conditions over a range of 150 nautical miles.
    (d) The transmitter complies with the range requirement specified in 
paragraph (c) of this section if:
    (1) The transmitter is capable of being matched to actual ship 
station transmitting antenna meeting the requirements of Sec. 80.863; 
and
    (2) The output power is not less than 60 watts peak envelope power 
for H3E and J3E emission on the frequency 2182 kHz and for J3E emission 
on the frequency 2638 kHz into either an artificial antenna consisting 
of a series network of 10 ohms resistance and 200 picofarads 
capacitance, or an artificial antenna of 50 ohms nominal impedance. An 
individual demonstration of the power output capability of the 
transmitter, with the radiotelephone installation normally installed on 
board ship, may be required.
    (e) The transmitter must provide visual indication whenever the 
transmitter is supplying power to the antenna.
    (f) The transmitter must be protected from excessive currents and 
voltages.
    (g) A durable nameplate must be mounted on the transmitter or made 
an integral part of it showing clearly the name of the transmitter 
manufacturer and the type or model of the transmitter.
    (h) An artificial antenna must be provided to permit weekly checks 
of the automatic device for generating the radiotelephone alarm signal 
on frequencies other than the radiotelephone distress frequency.
