S97 Playlist
S97 is a former numbers station believed to have operated in the United States during the Cold War era. Numbers stations are shortwave radio broadcasts used to transmit coded messages, often to intelligence operatives. S97 is notable for its use of synthesized voice transmissions, which recited strings of numbers thought to be encrypted messages. The station's exact purpose, origins, and operators remain unconfirmed, though it is widely speculated to have been linked to espionage activities. S97 ceased operations in the late 20th century as numbers station activity declined globally.
