Portable radio receivers and radios on p / p.DomesticThe portable VHF-FM radio "Vestnik-401" has been produced by the Kursk plant "Mayak" since 1988. The Vestnik-401 radio receiver was created on the basis of the Iren-401 radio receiver and, in addition to its design, weight and dimensions, is similar to it. The receiver is designed to receive broadcasting stations in the VHF range of 65.8 ... 74 MHz. Receiver sensitivity 18 μV. Single signal selectivity 30 dB. The range of reproducible frequencies is 450 ... 3150 Hz. Rated output power 70 mW. Power supply - battery of "Krona" type. Quiescent current 23 mA. Receiver dimensions 120x70x31 mm. Weight with food 230 gr. The receiver `` Vestnik RP-301 '', produced since 1992, does not differ from the 401 model according to the electrical circuit and design. A higher class of the model was assigned due to a drop in consumer demand and an influx of Chinese radio equipment into the country. In some batches of 2 radio receivers, the KR-198NT4-A microcircuit (transistor assembly) is replaced by transistors.
