On the history of the Soviet radio in 1945-1965

Postwar radio developed in the Soviet Union as an integral part of a unified system of long-distance telecommunications, built with the combined use of wire, cable and radio equipment. Radio communications in the Soviet Union was divided into two main groups: state radio service (Ministry of Communications) and departmental radio (other ministries and departments for office and industrial uses). This separation has been found in other sub-sectors of the Soviet telecommunications. In the 1960s began the implementation of transmitters and receivers with single-band modulation. The main advantages of single sideband radio in double narrowing band frequencies emitted by the transmitter, and to increase the reliability and communication range. The first of these advantages increases the number of channels in the radio frequency range and lower distortion, the second - better to use the power of transmitting devices. In the post-war period for the purpose of broadcasting begins using the new frequency range - meter waves. This band had many times greater capacity and allows arranging quality broadcasting with broadband frequency modulation. In frequency modulation increased noise immunity, in addition, in the meter wave range the level of atmospheric and industrial noise was significantly lower than in the long, medium and short wavelengths. The largest scale of construction and upgrading broadcast received during the seven-year period (1959-1965). At the radio centers were set, as a rule, local transmitters capacity of 100, 150 kW or more with anode modulation with more advanced radio tubes and parts with a high degree of efficiency. In the mid 1960s were commissioned the so-called syn-chronic broadcast networks. The advantage of such networks was the possibility of the work of many radio stations on a small number of frequencies. Network of cable and radio relay lines, through which the central radio programs broadcast on a special wideband radio channels, provides high-quality performance, expanded. The development of a radio receiving network in the post-war years proceeded in two directions: expanding the air-network, that is, increasing the number of radio receivers for personal use, and the development of wired broadcasting - growth in the number of translational radio outlets. The radical change in both quantitative and qualitative composition of the broadcasting transmission network in the country has made it possible to expand the central union, national and local broadcasting, as well as external (foreign) radio. Established by the mid 1960s in the USSR network of radio stations on the long, medium, short and meter waves in technical means was one of the most powerful in the world.
