Ural-47 is a six-lamp receiver powered from an alternating current network. Frequency ranges: DV 150 ... 420 kHz, SV 520 ... 1500 kHz, KV 4.4 ... 15.5 MHz. Receiver sensitivity is about 100 μV in all ranges. Selectivity 26 dB. The maximum output power of the amplifier is 4 W. The range of sound frequencies when receiving radio stations is 100 ... 4000 Hz. Power consumption 80 watts. Initially, the receiver was named as "Ural-47m", apparently the letter "m" meant modernization. It is known that the Ural-47 radio was the first to be produced and it was also produced until 1949, and the receiver began to be produced later and was discontinued in 1948. In addition to the absence of EPU and commutation, as well as the design of the case, the receiver, in contrast to the radio, had a different purpose of the control knobs.
