R-158

Transceiver semiconductor VHF radio station, with simplex frequency modulation and tone dialing.

Designed for radio communications with the same type of radio stations and other types of radio stations, similar in range, in place, on the go, on the move or in the parking lot, when installed in a car.

The receiver is assembled according to a superheterodyne circuit with two transformations.

The radio station is powered by a +12 V battery located in a special compartment of the radio station housing.

The R-158 was a full-time radio station of the platoon commander , with the help of which it was possible to communicate with both the company commander and the battalion headquarters .

Antenna matching device for the radio station "R-158" is not provided.

The radio station kit includes:

• a radio station;
• shoulder bag for carrying a radio station;
• antenna - whip, Kulikov designs;
• a wire in an insulating sheath for arranging a λ-shaped traveling wave antenna ;
• a low-frequency device in the form of a micro-telephone headset, consisting of a DEMSh-1A microphone, a microphone amplifier and a headphone (in one ear);
• A cord with a connector and clamping terminals for recharging the battery or operating the radio station from the on-board network.

In terms of external dimensions, the R-158 radio station in the bag was commensurate with the officer field bag adopted by the Ground Forces of the USSR Armed Forces .
