It is intended to serve as the basic HF device in the command of the infantry battalion for liaison with the regiment-brigade. It is made in transistor technology and massive "RIZ" FET transistors are used.

It works in the frequency range from 2MHz to 12MHz, operating modes CW, SSB and AM. The frequency is controlled by a frequency synthesizer with direct synthesis. The frequency is set with 4 decade switches in steps of 1KHz. The output power of the transmitter is 15W pep, and it is provided by a transistor linear amplifier. Its intermediate frequency is quite low at 500KHz and its reception and transmission bandwidth is controlled by the SSB crystal filter of the "Mihailo Pupin" Institute. It is powered by a DC voltage of 12V from an external source
