The radio receiver was created on the basis of the "Alpinist" receiver circuit with the addition of an IF cascade and recalculation of the nominal values "u200b"u200bof parts for 4.5 V. In those years, the appearance of this model, with the possibility of using it in stationary and portable modes, was an achievement for the USSR.
