This station began broadcasting as WWWF on September 3, 1949, with a 1,000 watt daytime-only signal. The station was licensed to Bankhead Broadcasting Company, Inc., whose sole owner was Walter Will Bankhead. Bankhead's first station, WWWB in Jasper, Alabama (1240 AM, now WJLX) was named for his initials. This Jasper station began licensed broadcasting with 250 watts of power on 1240 AM on November 2, 1946... In 1955, the station got a construction permit from the FCC that allowed then to move to the current 1360 AM broadcast frequency and increase signal power to 1,000 watts. The station now holds the callsign WIXI. Additionally, in January 2010, acting on engineering data filed with the FCC, WIXI increased its daytime power to 12,000 watts.. In 1962 WWWB-FM 102.5 was added in Jasper, (now WDXB licensed to Pelham, Alabama broadcasting to the Birmingham Metro area, with an effective radiated power of 90,000 watts) WWWB-FM was initially signed on the air with an effective radiated power of 39,000 watts... WWWB's sister station WWWR in Russellville, Alabama (920 AM, now WGOL) which also went on the air in 1949, was named for "Walter Will's Russellville". WWWF was similarly chosen as the callsign to mean "Walter Will's Fayette".

In the 1960s, WWWF broadcast a format called "Something for Everyone" featuring country in the morning, a half-hour of Gospel music at midday, easy listening until mid-afternoon, then rock music for the rest of the day. In the 1980, WLDX changed their format to country music full-time.
