  § 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 on 2182 kHz and J3E
   emission on the distress and safety frequencies listed in § 80.369(b).

   (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 § 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 § 80.371(b) of this part under
   normal daytime operating conditions.
