Portable radio `` Electron ''.
Portable radio receivers and radios on p / p.DomesticSince 1965, the portable radio receiver "Electron" has been experimentally produced by the Sverdlovsk Economic Council. The radio receiver operates in two wave bands: DV and MW. It is built on 6 transistors and one diode. The receiver has the following stages: A frequency converter on a P402 transistor, a two-stage IF amplifier on a P401 transistor, a detector on a D9E diode, a LF preamplifier on a P13A, a push-pull terminal ULF on two P13A transistors. Rated output power is not less than 50 mW. Sensitivity in the range of DV - 3 mV / m, in the range of MW - 1.5 mV / m. Selectivity at a detuning of ± 10 kHz in the LW and MW ranges not less than 20 dB. The band of reproducible sound frequencies is 450 ... 3000 Hz. Powered by a Krona battery or a 7D-0.1 battery, current consumption at rest 7 mA. Loudspeaker 0.1GD-6. The assembly is carried out on a printed circuit board. Receiver dimensions 121 x 77 x 35 mm. Weight 350 gr. The radio was developed in several design options, was experimentally released in a small batch, but did not go into mass production.
