Radio Moscow’s interval signal.
Radio Moscow (Pадио Москва) was the official international broadcasting station of the Union of Soviet Socialist Republics until 1993.
After the fall of the Soviet Union It was reorganized with a new name: Voice of Russia, which has also since been reorganized and renamed Radio Sputnik.
At its peak, Radio Moscow broadcast in over 70 languages using transmitters in the Soviet Union, Eastern Europe, and Cuba.
