Sec. 80.873 VHF radiotelephone transmitter.
(a) The transmitter must be capable of transmission of G3E emission on
156.300 MHz and 156.800 MHz, and on frequencies which have been specified
for use in a system established to promote safety of navigation. Vessels in
waters of other Administrations are required to communicate on any channel
designated by that Administration for navigational safety in the bands
specified in Sec. 80.871(d).
(b) The transmitter must be adjusted so that the transmission of speech
normally produces peak modulation within the limits of 75 percent and 100
percent.
(c) The transmitter must deliver a carrier power between 8 and 25 watts into
a 50 ohm effective resistance. Provision must be made for reducing the
carrier power to a value between 0.1 and 1.0 watts.
(d) The transmitter complies with the power output requirements specified in
paragraph (c) of this section when:
(1) The transmitter is capable of being adjusted for efficient use with an
actual ship station transmitting antenna meeting the requirements of
Sec. 80.876; and
(2) The transmitter has been demonstrated capable, with normal operating
voltages applied, of delivering not less than 8 watts of carrier power into
50 ohms effective resistance over the frequency band specified in
Sec. 80.871(d). An individual demonstration of the power output capability of
the transmitter, with the radiotelephone installation normally installed on
board ship, may be required; and
(3) It is certificated as required by subpart F of this part.
