Owing to its 50,000 watt clear channel signal that could be received in Cuba, KAAY provided residents of the island nation an important cultural link to the outside world in the years following the Cuban Revolution. During the 1962 Bay of Pigs Invasion, the United States government used the station to broadcast anti-Castro propaganda while working to win the release of Cuban exiles who participated in the failed exercise. KAAY was an inspiration to Cuban rock musicians and rock fans who tuned into "Beaker Street" late at night, keeping themselves informed about American music and underground music in the 1970s. They listened undercover with Soviet-made transistor radios. In the late 1960s the station's jingle started out with roaring thunder followed by a deep voice: "Fifty thousand watts of music power, K-double-A-Y, Little Rock".
