Ishim stationary transistor radio.
Amplifying and broadcasting equipmentSince 1974, the stationary transistor radio "Ishim" has been produced by the Kirov Petropavlovsk Plant. Kazakhstan. All-wave transistor radio receiver of the highest class "Ishim" is intended for completing broadcasting radio centers. It provides reception of broadcasts of radio broadcasting stations operating in the LW, MW, HF bands of 4 sub-bands with a continuous range of 3 ... 18 MHz and VHF. The scale is graduated in megahertz. Tuning in the AM and FM bands is separate, with fixation of the tuning knobs. The possibility of using different antennas and dual reception is provided. The radio has various output voltages that can be used for subsequent amplification or monitoring through a loudspeaker or headphones. Sensitivity in the ranges: DV, SV, KV - 50 µV, VHF - 10 µV. Attenuation of the mirror channel: in the range: LW 60 dB, SV 50 dB, HF 32 dB, VHF 30 dB. The drift of the local oscillator frequency from self-heating in the AM ranges of 2 ... 3 KHz, FM 20 KHz. The receiver has 3 fixed bandwidths: narrow, medium and wide. AFC coefficient in the VHF range is not less than 4 units. Power supply from an alternating current network with a voltage of 127 or 220 V or from a direct current source with a voltage of 27 V. Power consumption from a network is 15 W. Receiver dimensions - 458x340x182 mm. Weight 15 kg.
