Portable radios Ural-301 and Ural-302.
Portable radio receivers and radios on p / p.DomesticSince 1971 and 1972, the Ural-301 and Ural-302 portable radios have been produced by the Sarapul Radio Plant. These are the first portable radio receivers in the USSR, assembled on hybrid integrated circuits. The receivers have the same circuit and design, the difference is the absence of AFC in the first model. The appearance of the models is the same. Any of the receivers is designed to receive in the LW, MW and HF bands in the KB-1 12.1 ... 11.6 MHz, KV-2 9.9 ... 9.4 MHz, KV-3 7.3 sub-bands. 3.95 MHz and in the VHF range 73.0 ... 65.8 MHz. In DV, SV, reception is carried out on a magnetic antenna, KB, VHF on a telescopic one. Sensitivity in DV - 2.5 mV / m, SV - 1.0 mV / m, KB - 500 μV, VHF - 100 μV. IF path AM - 465 kHz, FM - 10.7 MHz. Adjacent channel selectivity - 30 dB. The average slope of the resonance characteristic slope in the FM range is 0.15 dB / kHz. The frequency band of the AM path is 315 ... 3550 Hz, FM - 315 ... 7000 Hz. The radio receivers use 6 Trap-2 hybrid integrated circuits. Loudspeaker type 0.5GD-31. Rated output power 0.4 W. Power supply of 6 A-343 cells or 2 336 batteries. Receiver dimensions 211x233x76 mm, weight with batteries 2 kg. Export receivers had other frequencies in the HF and VHF bands.
