THIS RADIO ON EBAY: https://www.ebay.com/itm/175214855152 --- Since 1974, the Rossiya-303 portable radio receiver has been produced by the Chelyabinsk manufacturing company Polet. The portable radio receiver of the 3rd class ''Russia-303'' is assembled on 8 transistors and 2 diodes. It is designed to receive radio stations with AM modulation, in the LW, MW bands, on an internal magnetic antenna and in the SW subbands, on a telescopic one. Frequency ranges: LW - 150 ... 408 kHz, MW - 525 ... 1605 kHz, SW-1 - 9.5 ... 12.1 MHz, SW-2 - 3.95 ... 7.3 MHz . The IF is 465 kHz. Sensitivity in the range LW - 1.5 mV / m, MW - 0.7 mV / m, SW - 100 μV. Adjacent channel selectivity in LW and MW is 46 dB. Selectivity for the mirror channel in the range LW - 26 dB, MW - 30 dB, SW - 14 dB. AGC action: when the input signal changes by 26 dB, the output voltage changes by 6 dB. Rated output power 100 mW. Band of reproducible frequencies - 300...3550 Hz. Power supply from 4 elements 316. Model dimensions 215x125x47 mm. Weight 1 kg. Since 1987, the Russia-303 receiver has been referred to as Russia RP-303. In terms of parameters, it is analogous to the described receiver, and the design is similar to the lilac receiver. However, to increase the range of items, the production of the Rossiya-303 model continued. During the production process, all elements of the radio receiver, such as a loudspeaker, a piezo filter and resistors and capacitors, were replaced with modern ones.
