Sec. 80.909  Radiotelephone transmitter.

    (a) The medium frequency transmitter must have a peak envelope 
output power of at least 60 watts for J3E emission on 2182 kHz and at 
least one ship-to-shore working frequency within the band 1605 to 2850 
kHz enabling communication with a public coast station if the region in 
which the vessel is navigated is served by a public coast station 
operating in this band.
    (b) The single sideband radiotelephone must be capable of operating 
on maritime frequencies in the band 1710 to 27500 kHz with a peak 
envelope output power of at least 120 watts for J3E emission and H3E 
emission on 2182 kHz and J3E emission on the distress and safety 
frequencies listed in Sec. 80.369(b). Single sideband radios installed 
on or before February 2, 1992, may be used until February 2, 1997, 
provided such radios are capable of operating on the frequencies listed 
in Secs. 80.369 (a) and (b), and at least half of the frequencies listed 
in Sec. 80.369(d).
    (c) The transmitter complies with the power output requirements 
specified in paragraphs (a) or (b) of this section when:
    (1) The transmitter can be adjusted for efficient use with an actual 
ship station transmitting antenna meeting the requirements of 
Sec. 80.923 of this part; and
    (2) The transmitter, with normal operating voltages applied, has 
been demonstrated to deliver its required output power on the 
frequencies specified in paragraphs (a) or (b) of this section into 
either an artificial antenna consisting of a series network of 10 ohms 
effective resistance and 200 picofarads capacitance or an artificial 
antenna of 50 ohms nominal impedance. An individual demonstration of 
power output capability of the transmitter, with the radiotelephone 
installation normally installed on board ship, may be required.
    (d) The single sideband radiotelephone must be capable of 
transmitting clearly perceptible signals from ship to shore. The 
transmitter complies with this requirement if it is capable of enabling 
communication with a public coast station on working frequencies in the 
4000 to 27500 kHz band specified in Sec. 80.371(b) of this part under 
normal daytime operating conditions.
