Transistor radio receiver `` Sokol-4 ''.
Portable radio receivers and radios on p / p.DomesticThe Sokol-4 transistor radio receiver has been produced by the Moscow Radio Plant since the 1st quarter of 1967. The Sokol-4 radio receiver is a small-sized superheterodyne assembled on eight transistors and two diodes. It is designed to receive radio stations in the DV, SV and HF bands. Reception in DV, SV is carried out on a magnetic antenna, and in HF - on a telescopic one. A headset can be connected to the receiver. The receiver is powered by four A-316 elements. Control with 4 knobs; settings, trim, range switch and volume control with power switch. Light weight, 950 g and dimensions of 215x125x47 mm, make the receiver easy to use. Radio frequency ranges: DV 735 ... 2000, SV 186 ... 570 and KV 25 ... 75 m. The KV range is divided into 2 sub-bands: KVl - 25 ... 31 m and KV2 - 41 ... 75 m. Export variants had other CV sub-bands. Sensitivity 1.8 mV / m at LW, 0.8 mV / m at MW, 150 μV at HF. Selectivity in the adjacent channel is 46 dB, the mirror channel at LW and CW is 26 dB, at KB - 12 dB. AGC provides a voltage change at the detector by 5 dB, with a change at the input by 26 dB. Rated output power 100 mW. Quiescent current 10 mA.
