Transistor radio receiver `` Sokol-3 ''.
Portable radio receivers and radios on p / p.DomesticSince 1967, the Sokol-3 transistor radio has been produced by the Moscow Radio Plant. Portable transistor radio receiver "Sokol-3" is designed to receive radio stations in the DV, SV bands on the internal magnetic antenna. It is assembled on seven transistors in a superheterodyne circuit. Average sensitivity in the range of DV - 1.2 mV / m, SV - 0.65 mV / m. Selectivity on the adjacent channel 26 ... 30 dB. The rated output power of the ULF on the 0.1GD-6 loudspeaker is about 100 mW, the maximum is 2000 mW. The range of reproducible sound frequencies is 300 ... 3000 Hz. Power is supplied from the Krona battery or from a 7D-0.1 battery. The quiescent current is 6 mA. Operability is maintained when the supply voltage drops to 3.8 volts. The operating time of the receiver from the Krona battery is at least 30 ... 40 hours, from the battery 12 ... 15 hours. Receiver dimensions 170x98x40 mm. Its weight is 500 gr. The receiver is equipped with a carrying handle. The price of a receiver with a Krone battery is 45 rubles 48 kopecks. In 1969, the release of the receiver was discontinued and the documentation was transferred to the Kyshtym radio plant, where it was produced since 1970 under the name Quartz-401. The rigid carrying handle has been replaced with a belt handle.
