The radio designer &quot;Electron-M&quot; has been producing the Zaporozhye semiconductor device plant since the 1st quarter of 1977. The radio constructor is a set of parts of elements and assemblies for assembling a direct amplification transistor radio receiver according to the 2-V-3 scheme, operating in the medium wave range. The receiver has a sensitivity of about 30 mV / m. Maximum output power 100 mW. The range of reproducible sound frequencies is 200 ... 5000 Hz. Power is supplied from the Krona battery. The price of a radio designer is 6 rubles. The set was produced by the plant until the first half of the 90s. With an almost unchanged electrical circuit, with a slight correction of the denominations of parts and designations in the circuit, the printed circuit board had several wiring options. RK was produced in different design options (three of them were seen), assembly and operating instructions (two were noticed) and in different packages (three were noticed), with different loudspeakers.
