Wearable radio station "Berth" (19R32NM-1a) was produced since 1973. It was used for communications in various services of the sea and fishing fleets: pilotage service, communications on board the vessel, etc. It was produced as a replacement for the Lotsman portable radio station due to a change in the frequency separation (from 50 to 25 kHz) between channels. "Berth" radio station consists of a transceiver unit, a battery (10 TsNK-09U2), a manipulator (microphone-loudspeaker), an antenna (half-wave and dipole pin in the form of two pieces of wire, mounted on the shoulder strap), carrying bags. The frequency range is 156.3 ... 158 MHz. The number of working channels is 4. The spacing between adjacent channels is 25 kHz. Modulation type - FM. Sensitivity (signal / noise 20 dB) - 1.5 µV. Transmitter output power is 1W. Battery supply voltage - 12.5 V. Battery operation time - 8 hours. Overall dimensions - 210x130x65 mm. Weight - 2.2 kg.
