Transistor radio `` Sonata ''.
Portable radio receivers and radios on p / p.DomesticSince 1965, the Sonata transistor radio has been produced by the Leningrad plant "Radiopribor". The radio was produced in several design options. The receiver differs from similar models in modern design, good sound quality, high electrical and operational parameters. Ranges: DV - 150 ... 408 kHz (2000 ... 735 m), SV - 525 ... 1605 kHz (571.2 ... 187.0 m), KV-1 - 3.95 ... 7.4 MHz (75 ... 41 m), KV-2 - 9.0 ... 12.1 MHz (31 ... 25 m). Maximum sensitivity in the ranges: DV - 1.0 mV / m, SV - 0.5 mV / m, KV - 50 μV. Real sensitivities are 2.0 mV / m, 1.0 mV / m and 200 μV. Selectivity on the adjacent channel in the LW and MW ranges is not less than 34 dB. Selectivity on the mirror channel in the ranges DV - 32 dB, MW - 26 dB, HF - 12 dB. IF 465 kHz. Rated output power 150 mW. The range of reproducible sound frequencies is 200 ... 4000 Hz. The radio receiver has a treble tone control, which provides a cut in frequency response at a frequency of 4 kHz - 12 dB. The receiver is powered by 2 KBSL-0.5 batteries. The dimensions of the receiver are 252x143x68 mm. Weight with batteries 1.9 kg. The model provides the ability to connect a headset or an additional speaker, external power supply, antenna and ground. Export radios had HF sub-bands from 16 to 50 meters.
