Black-and-white television receiver '' TM-3 '' Pioneer.
Black and white televisionsDomesticThe television receiver of the black-and-white image "TM-3" Pioneer has been producing the Leningrad plant named after Kozitsky since 1934. The Pioneer TM-3 mechanical TV is developed on the basis of the EKL-34 receiver and has a mechanical scanning unit and image and sound receiving channels. The TV provides for simultaneous restructuring of channels in the CB range, automatic signal level control and automatic synchronization. In the absence of image signals, the mechanical part of the device did not turn on and it could work as a receiver. On the upper screen with a lens, it was possible to view a 5x7 cm image with a resolution of 24 to 48 lines. To listen to the soundtrack, an external loudspeaker was needed. The name '' TM-3 '' stands for Mechanical TV, 3 development, and Pioneer as a pioneer. The TV received programs with horizontal or vertical scanning, for the second, the neon lamp was manually shifted by 90 degrees and the program could be watched on the side screen. Movies were broadcasted horizontally, and from the studio with a vertical program. The plant produced about 200 TVs, but for a number of reasons it did not go into mass production. In Leningrad, in addition to the local TV program in the evening and at night, it was possible to receive TV programs from Germany and England on TV.
