WVOK/Birmingham signed on at 690 AM in 1947. It broadcast at 50,000 watts, but was a daytimer.
This 1950 ad touts WVOK as “The Voice of Dixie” and highlights its “‘live hill billy music.”
The station rode the Top 40 wave in the 1960s and 1970s as The Mighty 690. Wikipedia says WSGN/Birmingham was the market leader with its pop format, and WVOK decided to go after rural listeners.
WVOK became “OK 69” country radio in 1976. The FCC allowed it to operate 24 hours a day in the early 1980s. WVOK switched to adult contemporary, oldies and classic country before flipping to sports talk in 1992.
The 690AM frequency is now WJOX. The WVOK call letters belong to WVOK-FM 97.9 (Hot AC) and WVOK-AM 1580 (Oldies) in Anniston, Alabama.
