Radio Moscow (Russian: Pадио Москва, tr. Radio Moskva), also known as Radio Moscow World Service, was the official international broadcasting station of the Union of Soviet Socialist Republics until 1993. 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.

USSR Shortwave broadcasting innovations

The USSR pioneered the use of HRS 8/8/1 antennas (horizontal dipole curtain, eight columns, eight rows, with electrically steerable pattern) for highly targeted shortwave broadcasting long before HRS 12/6/1 technology became available in the west. HRS 8/8/1 curtain arrays create a 10-degree beam of shortwave energy, and can provide a highly audible signal to a target area some 7,000 km away.
