The
All-Union Radio was established in
Moscow and began broadcasting on November 23, 1924, initially on long and medium waves, later also on ultra-short waves, distributed via the wire broadcasting system on Channel 1 (directly in the audio frequency band, as a result of which the simplest subscriber loudspeaker was required for reception). The channel was changed to the
All Union First Programme in 1945 with a political focus. In 1960, a duplicate of the First Program of All-Union Radio for the
Russian Far East was introduced (Khabarovsk 270 kHz), in 1964 a second duplicate of the First Program of All-Union Radio was introduced. By the end of the 1970s, there were four duplicates of the First Program of All-Union Radio. On January 1, 1991, the name
Radio-1 was assigned to the 1st Program of All-Union Radio. On September 2, 1991, the retransmission of Radio-1 was transferred from the 1st to the 3rd channel of wired broadcasting, the frequencies of Radio-1 on ultra-short waves were transferred to
Radio Russia, and in those regions and areas where Radio-2 was retransmitted in this range, Radio-1 was transferred to its frequencies. The other open frequencies of the All Union First Programme were taken over by the state radio channels of the
newly independent republics. ==See also==
