Portable radio "Electron" was developed in 1964 and prepared for release in 1965. The radio operates in two wave bands: LW and ST. It is built on 6 transistors and 1 diode. The receiver has the following stages: Frequency converter on the P402 transistor, two-stage UPCH on the P401 transistor, detector on the D9E diode, LF preamplifier on P13A, two-stroke terminal ULF on two P13A. ULF output power not less than 50 mW. Sensitivity in the range of DV - 3 mV / m, in the range of SV - 1.5 mV / m. Selectivity with detuning by Â± 10 kHz in the ranges of the Far and Continuous not less than 20 dB. Band of reproducible frequencies 450 ... 3000 Hz. Powered by a Krone battery or a 7D-0.1 battery, the current consumption in quiescent mode is 7 mA. Loudspeaker in the receiver 0,1Ð“Ð”-6. Installation is made on the PCB. The dimensions of the receiver 121x77x35 mm, weight 350 g. The receiver was developed in several design options, but did not go into mass production.
