Radio receivers 'Sport-3' and 'Sokol-6'.

Portable radio receivers and radios on p / p.DomesticRadio receivers "Sport-3" and "Sokol-6" - experimental models of Dnepropetrovsk and Moscow radio plants in 1970. Both radios, except for different designs and factories that prepared their release, are the same. The model is a 3rd class radio receiver designed to receive broadcasting stations in the following ranges: DV, SV, HF and VHF-FM. HF band is divided into 2 sub-bands. The radio receiver has an internal ferrite antenna for receiving on DV, SV and a retractable telescopic antenna for receiving on HF sub-bands and VHF-FM, two jacks: telephone and for connecting an external antenna. Main characteristics: Frequency ranges: DV 150 ... 408, SV 525 ... 1605 kHz. KV-2 3.95 ... 7.3, KB-1 9.5 ... 12.1 MHz. VHF-FM 64 ... 75 MHz. The sensitivity of any radio receiver when receiving on an internal ferrite antenna is not worse: in the range of DV - 2.5 mV / m, CB - 1.0 mV / m. Sensitivity on HF bands with a telescopic antenna 200 µV, in VHF-FM 50 µV. IF AM path 465 kHz, FM 10.7 MHz. Selectivity (at detuning ± 10 kHz) 46 dB. The frequency band when working on a loudspeaker when receiving in the AM path is 300 ... 3500 Hz, in the FM 250 ... 5000 Hz. Rated output power 100 mW. Power supply - 4 elements 316. Average current consumption 25 mA. The Moscow Radio Plant also prepared an export version of the Sokol-6 receiver and even produced several hundred copies. In this case, the frequency ranges of DV and MW did not change. HF sub-bands had overlapping: KV-1 14.7 to 18 MHz and KV-2 from 6 to 12.1 MHz. VHF range covered the band from 88 to 107 MHz.
