Portable radios Sokol-M and Sokol-403.
Portable radio receivers and radios on p / p.DomesticPortable radios "Sokol-M" and "Sokol-403" have been produced since 1970 and 1971 by the Moscow Radio Plant. The Sokol-M radio receiver was created on the basis of the Sokol receiver and operates on the Far East and East. Sensitivity 3 and 1 mV / m. Selectivity about 20 dB. Its circuit is practically similar to the Sokol receiver circuit, only the P-422 HF transistors were replaced by the GT-309, and the P-14 and P-15 low-frequency transistors were replaced by the GT-108. The parameters of the receiver have changed little, and its rated output power has decreased to 50 mW, respectively, the operating time from the Krona-VTs battery has increased to 100 hours. The design of the radio was the same as that of the Sokol-403 receiver produced since 1971. The Sokol-403 radio receiver is designed for reception in the DV and SV bands. Reception is performed on an internal magnetic or external antenna. Sensitivity to DV, SV to the internal antenna 1 and 0.5 mV / m; selectivity on the adjacent channel 20 dB. The AGC system provides a 10 dB change in the output voltage when the input voltage changes by 26 dB. The range of reproducible frequencies is 450 ... 3000 Hz. Powered by a Krona-VTs battery or a 7D-0.1 battery. Includes a charger that can charge the battery without removing it. The performance of the model is maintained when the power supply is reduced to 5.6 V. The dimensions of the receiver are 157x92x30mm. Weight 400 gr. Includes leather case. RP `` Sokol-403 '' was produced until 1982. It was also produced for export with several names. A set of parts and assemblies for self-assembly of the receiver was also produced.
