Black and white televisionsDomesticThe television receiver of the black-and-white image "ATP-1" has been producing the Aleksandrovsky radio plant since December 1938. "ATP-1" - Subscriber Television Receiver No. 1 is developed on the basis of the "TK-1" TV set. At the end of 1937, a group of enthusiasts from the Leningrad Scientific Research Institute of Communications (Scientific Research Institute of Communications) began to develop the principles of wired (on separate cables) subscriber television. The whole work took just over one year. The production of the TV set "ATP-1" was mastered at the Aleksandrovsky Radio Plant according to its own developments and according to the TK-1 model. It was a television of a simplified design for the reception of the Moscow experimental television center for 343 lines through the broadcasting node. 25 TV sets were manufactured. First, there was a demonstration of the principle of wired television to interested organizations, and then, in the fall of 1939, in the city of Moscow, at No. 17 on Petrovsky Boulevard, work began on organizing a receiving center and wired television broadcasting. In early May 1940, the television hub began its first wire broadcasts to 25 subscribers. In the absence of television programs, two radio broadcasting programs were transmitted via cables, the necessary of which was switched by the subscriber. Almost immediately, the modernization of the TV began, which consisted in its some simplification. The TV began to be called "ATP-2", but apart from prototypes, things did not go further because of the lack of support for the idea by interested persons and organizations. In June 1941, before the start of the war, the wired television project was curtailed.
