Radio Rodina "Rodina" since 1945 produced the Moscow Radio Works. Motherland is the first Soviet radio of the post-war years. It is a superheterodyne on 6 small, battery-powered lamps. There are three ranges: DV 2000 ... 733 m, SV 545 ... 200 m and KV 32.6 ... 24.6m. Sensitivity 100 µV. The adjacent channel selectivity is 26 dB. PCh 460 khz. Output power 200 mW. The receiver is assembled on a metal chassis, inserted into a wooden case. On the front panel, on the left, is the handle of the switch and tone control. This knob has 3 positions: the left one corresponds to power off; the second turns on the power and does the work of the receiver with the attenuation of higher audio frequencies; in the third, the RF attenuation is turned off. Next knob volume control. Further in the right part, the range switch and the fine tuning knob are located. The scale of the model has a graduation in meters and in kilohertz. The receiver is powered by elements of 6C-MVD. This battery lasts for 600 hours. Consumed filament current 0.5 a. Anode current in the absence of signals does not exceed 6 ma and reaches 10 ma at the time of reception. Therefore, anode batteries of any type with a voltage of 120 V can be used for anode power. One of the features of the receiver is the presence of an anode voltage indicator in the form of a neon bulb located above the scale. The light is on if the anode battery voltage is not lower than 80 volts. At this voltage, the receiver can still work. Dimensions of the model 480x339x214 mm, weight 8.8 kg. Since 1946, the Voronezh Plant to increase the range produced radio "Elektrosignal" (ELS), in some series it was called as "Homeland" by design similar to the above described receiver "Homeland". The receiver was produced in several variants of external design.
