Portable transistor radio "Mir" from the beginning of 1962 produced the Minsk Radio Plant. The superheterodyne "Mir" radio receiver was developed at the SKB of the Minsk Radio Works. The receiver is a superheterodyne operating in the DV and SV ranges, assembled on six P401 and P13A transistors, powered by a Krona battery or a 7D-0.12 rechargeable battery with a voltage of 9 volts. Reception is carried out on internal magnetic antennas. The average sensitivity of the receiver in the ranges: DV - 3.0, CB - 2.0 mV / m. The adjacent channel selectivity is 16 ... 20 dB. The rated output power is 70 mW with a non-linear distortion factor of 10%. The band of sound frequencies reproduced by a speaker 0,25GD-1 450 ... 3000 Hz. The effect of AGC is 12 dB. IF - 465 kHz. The quiescent current is 5 ... 7.5 mA, the efficiency is maintained when the power is reduced to 5.6 V. When the radio is powered from the battery, it is recharged from the mains without removing it from the compartment. The duration of continuous operation of the receiver at an average volume from a Krone battery is ~ 20 hours, from a 7D-0.12 battery - 10 hours. The dimensions of the receiver are 125x72x38 mm. Weight with a battery of 340 grams. The body is made of colored polystyrene. The price of the receiver is 41 rubles 40 kopecks.
