Description

Radio receiver from the plane of the Soviet bomber USSR 1960
A series of DV / SV / HF radio receivers.
US
US-P 2US-P 1
The US receiver provides the ability to receive signals at frequencies from 175 kHz to 12 MHz, which corresponds to fixed waves from No. 7 to No. 480
The entire range is divided into five sub-ranges:
1st sub-range 7 ... 14 lbs. in. Fixed waves
2nd sub-range 15 ... 35 lbs. in. are given in the table.
3rd sub-range 36 ... 86 lbs. in. Fixed waves
4th sub-range 85 ... 200 lbs. in. marked on the scale
5th sub-range 200 ... 480 lbs. in. marked on the scale.
Intermediate frequency 112 kHz.
The sensitivity of the receiver with a voltage at the output of the receiver equal to 15 volts on two pairs of headphones connected in series is:
in telegraph mode 1 ... 4 μV
in the telephone mode 2 ... 10 µV.
Receiver consumption in high voltage circuit at 200 V, no more than 50 mA. On the heating circuit, the receiver consumes 0.6 A when powered from 25.2 V and 1.2 A from 12.6 V.
US-P 3
In 1937, at the Moscow plant No. 203, an experimental batch of new US radio receivers (universal superheterodyne) was produced. This radio was produced under the third program of rearmament of the Red Army and played a huge role in organizing communications among the troops during the Second World War.
The US radio receiver was originally intended for completing the RSB aviation radio stations (bomber aircraft radio station), as well as the RSB-F airfield service car radio stations.
The newly created receiver, in comparison with the previous models, had great advantages, such as high sensitivity, compactness, ease of use and high reliability.
With the beginning of the Second World War, the need for such receivers increased sharply, tk. RSB-F radio stations began to be used in the ground forces. Due to the threat of the encirclement of Moscow, the production of receivers was transferred to the city of Gorky at plant No. 197. After the end of the Second World War, such receivers began to be used in the civilian sphere. In 1948, the receiver was modernized (replacing the 6L7 lamp with a 6SA7 lamp), and it was named US-P (for military purposes) and PR-4-P (for civilian purposes). In 1952, the production of radio receivers at the ZIL plant (former plant No. 197) was discontinued and transferred to the plant. M.V. Frunze (Gorky).
The design of the receiver clearly shows the American school of radio engineering and American production technology. Initially, the receivers were equipped with modern (at that time) American radio tubes of the metal series. Some of the components, such as resistors, mica capacitors and toggle switches, were also made in America. As the production of these products was mastered in the USSR, imported radio tubes and components were replaced by domestic ones.
