KAAY began in the early 1960s as a clear-channel Top-40 station in Little Rock, Arkansas. The night signal of "The Mighty Ten Ninety" reached from Manitoba in the north to Cuba in the south.
In the late 1960s, at 11 PM each night, KAAY dropped the Top-40 format and aired three hours of "underground" rock music on the show Beaker Street hosted by Clyde Clifford. This show pre-dated the 1970s rise of FM album-oriented and progressive rock stations. Clifford did his program at the transmitter site rather than KAAY's downtown studios as he was also the overnight broadcast engineer. He played sound effects and instrumental music between songs to mask the noise of the transmitter. Beaker Street lived on with various hosts at various stations and continues to this day--Sunday nights at 7 on Classic Rock KKPT "The Point 94.1"
In 1985 KAAY became a Southern Gospel station and later transitioned to Contemporary Christian. Today they're the most powerful Religious station in the United States pumping out Christian Talk with 50,000 watts 24 hours a day.
