Portable transistor radio `` Mir ''.

Portable radio receivers and radios on p / p.DomesticSince the beginning of 1962, the portable transistor radio receiver "Mir" has been producing the Minsk Radio Plant. The Mir superheterodyne radio receiver was developed at the Special Design Bureau of the Minsk Radio Plant. 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 9-volt rechargeable battery. Reception is carried out on internal magnetic antennas. Average receiver sensitivity in the ranges: DV - 3.0, SV - 2.0 mV / m. Selectivity on the adjacent channel - 16 ... 20 dB. Rated output power 70 mW at 10% THD. The band of sound frequencies reproduced by the loudspeaker 0.25GD-1 450 ... 3000 Hz. The AGC action is 12 dB. IF - 465 kHz. The quiescent current is about 5 ... 7.5 mA, operability remains when the power supply drops to 5.6 V. When the radio is powered by a 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 the Krona battery ~ 20 hours, from the 7D-0.12 battery - 10 hours. The dimensions of the receiver are 125x72x38 mm. Weight with battery 340 grams. The body is made of colored polystyrene. The price of the receiver is 41 rubles 40 kopecks.
