Since 1957, the Shevchenko Kharkiv plant has produced a radio receiver and a radio tube lamp network "Kharkov" since 1957. The receiver is similar in design, construction, and construction of an electrical circuit to a '' Beacon '' radio receiver. The ranges of received frequencies: DV, SV standard, in KV-1 8.5 ... 12.1 MHz, KV-2 3.95 ... 7.65 MHz, in the FM range 64.5 ... 73 MHz. Sensitivity in the ranges of DV, CB 200 mV, both HF 300 mV, in the VHF-FM range 20 mV, from the pickup adapter 0.15 V. Selectivity on the adjacent channel is 26 dB in AM, 20 dB in VHF-FM. The selectivity on the mirror channel is 36 dB in DV, 20 dB in CB and 14 dB in the HF subbands. When received in AM, the range of reproducible sound frequencies is 100 ... 4000 Hz, in FM 100 ... 7000 Hz. Nominal output power on two loudspeakers 1GD-5 (later 2GD-3) 2 watts. Power consumption 55 watts. The following lamps are used: 6N3P, 6I1P, 6K4P, 6H2P, 6N2P, 6P14P, 6E5S. There are tone controls for high and low frequencies, the IF bandwidth control combined with the tone knob. The receiver dimensions are 510x360x285 mm, its mass is 11.5 kg. The price is 87 rubles 95 kopecks from 1961. Radiola, except for the addition of electric power supply and switching, is similar to the receiver. After the modernization of 1959, the parameters of the models changed. The KV-1 subranges are changed to 3.95 ... 7.5 MHz and KV-2 9 ... 12.1 MHz, the sensitivity in KV is increased to 200 μV, the selectivity is up to 30 dB in the DV and SV bands, the audio frequency band in World Cup and the work of the EDA was 80 ... 10,000 Hz, in AM 80 ... 4000 Hz. Power consumption 60/75 watts.
