The antenna socket is adapted to attach the Kulikov's type antenna. The output of the receiver is designed for simultaneous connection of two pairs of low-resistance headphones and a wireline with an impedance of 1500 ohms.

The receiver was developed in the design bureau of the
Aleksandrovsky radio factory in 1949 under the direction of V. M. Khakharev and M. E. Movshovich using the R-253 "Alfa" (Р-253 «Альфа») receiver as a basis for the design. Serial production began in 1954, and it was adopted by the Soviet military

The receiver is assembled in a cabinet with two compartments. To the right is placed the receiver itself, and to the left are installed power sources and stored accessories - a portable lamp, headphones, and a whip antenna. The casing is plywood, with a duralumin sheet on the outside. The casing and

Due to the use of directly heated filament valves, the radio consumes a modest amount of power (about 4 W), which is comparable to that of similar transistor radios.
