Portable radio receivers and radios on p / p.DomesticPortable radio receivers "Riga-302" and "Riga-302A" since 1969 have been producing the Riga Radio Plant named after A.S. Popov. The radio receiver "Riga-302" and "Riga-302A" are portable type 3 superheterodyne assembled on 9 transistors and 4 diodes. Riga-302A has an AFC system. Receivers are designed to receive radio stations operating in the ranges of long, medium and ultrashort waves. For the USSR, the VHF-FM range was standard: from 65.8 to 73.0 MHz, and for export versions of radio receivers, depending on the country: from 87.5 to 100 MHz and from 87.5 to 108 MHz. The export models were named Astrad and Vega, as well as the digital name F3TR9. For the USSR, radio receivers were produced without indices, there was just the name `` Riga-302 '', as well as with the index `` A '', and for export, radios were exported with indexes `` B '' and digital. In 1971, the receivers underwent modernization, after which they began to be referred to as "Riga-302A-2". Receiver sensitivity in the ranges: DV - 1.2 mV / m, SV - 0.8 mV / m, VHF - 35 μV, FM - 35 μV. Output maximum power 230 mW, nominal 150 mW. The band of reproducible sound frequencies in the AM path is 300 ... 3500 Hz, in the FM / FM path - 300 ... 7000 Hz. The acoustic system of the models consists of one loudspeaker type 0.25 GD-2. The receiver is powered by six cells of type 316. The duration of continuous operation from a set of batteries is 50 hours. The dimensions of the model are 220100x48 mm. Its weight is 800 gr.
