Radio Rodina-52 since 1952 produced the Chelyabinsk Radio Plant and the Voronezh plant Elektrosignal. The receiver was developed in 1951 by the design bureau of the Voronezh plant '' Electrosignal ''. The receiver replaced the model "Motherland-47" and became the first in the USSR superheterodyne receiver of the 2nd class on finger lamps. With high sensitivity and selectivity, it is economical. In addition, the scheme has a device that allows you to reduce energy consumption when you do not need to work at high volume. On the front panel, on the right is a double knob: the large one serves for switching ranges, a small one for tuning. The dual handle on the left performs several functions: large - the power switch and tone control, small volume control. The tone control has the following positions: "Off", "Wide", and "Narrow Band". In the position "Narrow Band" the high frequencies are cut off. On the left side wall there is a switch of the type of work in three positions: for work in the economical mode "MM" (Low power), in the normal mode "BM" (High power) and for operation from the pickup "ES". At the back are the antenna and ground jacks, the pickup and the extra loudspeaker. Using the same plug, the receiver can be included in the broadcast network. To connect the battery receiver is equipped with a cord with pads. In addition, the kit includes an adapter that allows you to use conventional batteries and anode. Radios '' Homeland-52 '' since 1954, worked on the batteries from the receivers '' Iskra-53 ''. The receiver has 4 ranges: DV 200 ... 723 m, CB 577 ... 167 m, KV1 76 ... 36 m and KV2 36 ... 24.8 m. Sensitivity to DV, CB 200 µV, KV 300 µV . The adjacent channel selectivity is 26 dB. Selectivity on the mirror channel on DV 36 dB, CB 30 dB, KV 12 dB. The range of reproducible sound frequencies is 100 ... 4000 Hz. IF 465 kHz. The inclusion indicator is a neon lamp located on the left above the volume control. The current consumption for the heat 520 mA in normal and 400 mA in economy mode.The consumed current in the "MM" mode with an output power of 100 mW is 8.5 mA, in the "BM" mode with a power of 300 mW - 12 mA. When the pickup is operating, the glow of the receiving part's lamps is turned off, and the output stage operates in the "BM" mode. A 3GD-3 loudspeaker (later 0.5GD-5) with a permanent magnet is installed in the receiver. Dimensions of receiver 450x310x225 mm. Weight 12.5 kg. Radio '' Homeland-52 '' was produced until mid-1960, having undergone during this time several modifications of the design and appearance.
