The radio receiver is designed to receive radio stations and to listen to the recording when the external EPU pickup is connected. The radio receiver is assembled on 5 radio tubes: 6А7, 6К7, 6Г7, 6П6С and 6Ц5С. The ranges of frequencies and waves: DV - 150 ... 415 kHz (2000 ... 723 m); MW - 520 ... 1600 kHz (577 ... 187 m); HF - 3.95 ... 12.1 MHz (76 ... 24.7 m). IF 465 kHz. Sensitivity in the ranges of DV, ST 100 ... 150 µV, KV 250 µV. The adjacent channel selectivity is 26 dB, mirrored in DV 50 dB, CB 32 dB, KV 24 dB. Output power 0.5 watts. Power consumption 35 watts. Dimensions of receiver 420x280x220mm. Weight 7.5 kg. Price after the monetary reform of 1961 - 43 rubles 10 kopecks. Since 1956, the plant produced a modernized receiver "Dnipro-52" which, by design, electrical circuit (except for the installation of a power transformer, instead of an autotransformer and the corresponding changes in the circuit and installation) and design, did not differ from that described. In the electrical circuit of the receiver, it is referred to as "Dnipro-56". However, until 1956, the plant produced small batches of receivers with a transformer, they can be easily distinguished by antenna and ground connections, while there was only an antenna socket in the receiver with an autotransformer.
