Since 1947, the networked tube radio Minsk has produced the Minsk Molotov Radio Plant. The radio "Minsk" was developed at the end of 1946 based on the model "Pioneer". It is a six-lamp mains-powered superheterodyne of the second class with ranges of LW, MW and two HF sub-bands. Wave bands: LW 150 ... 410 KHz, SV 520..1500 KHz, KV-I 4.3 ... 12.2 MHz, KV-II 14.87 ... 15.44 MHz. IF 465 kHz. Sensitivity 150 µV. Selectivity on the neighboring channel is 20 dB, on the image channel in the ranges of DV, CB - 30 dB, KV - 12 dB. Output power about 2 watts. Band of reproducible frequencies 100 ... 4000 Hz. Power consumption 60 watts. The receiver has a tone control for high sound frequencies, which simultaneously jumps the IF bandwidth. A small batch of radio receivers "Minsk" was released with two HF bands, apparently the data of this batch became the basis for the description of the directory, then with only one stretched.
