The souvenir radio receiver "Svirel" has been produced by the Orsha Red October plant since 1981. The radio receiver is assembled using 12 transistors and 3 diodes and is designed to receive programs from radio broadcasting stations in the medium wave range via a built-in magnetic antenna. IF - 465 kHz. Sensitivity - 2.5 mV/m. Selectivity in the adjacent channel is 16 dB, in the mirror channel - 26 dB. When the signal at the receiver input changes by 26 dB, the AGC system provides a change in the output signal by 6 dB. Rated output power at harmonic distortion 7.5% - 40 mW. Maximum output power 60 mW. The range of reproduced frequencies in terms of sound pressure is 400...2500 Hz. Power source: 2 elements AA. The current consumed without a signal at the input is 15 mA. Acceptable radio reception is maintained when the batteries are discharged to 2 V. The operating time of the receiver, when listening at medium volume, is about 40 hours. Receiver dimensions - 140x712x18 mm. Weight without batteries 180 grams.
