The radio receiver is made on the basis of the Geolog radio receiver, differing in the use of three microcircuits of the K237 series.

They work in a frequency converter, local oscillator, IF amplifier, detector and LF preamplifier.

To ensure high selectivity in the adjacent channel, the piezoceramic filter used in the Geolog model was replaced by a four-loop FSS.

To raise the frequency response in the region of low sound frequencies, a T-shaped low-pass filter is included at the ULF input.
