[2] Licensed to Columbus, Georgia, United States, the station serves the Columbus/Phenix City/Auburn area.

As 540 AM is a Canadian and Mexican clear-channel frequency, WDAK must reduce power during nighttime hours in order to protect the skywave signals of the dominant class A stations on the frequency: CBK, CBT and XEWA.

After the TV station was sold in 1958, WDAK was granted 5,000 watts by day, 500 watts by night on 540 kHz, with a new transmitter site and three towers located 5 miles west of Phenix City, Alabama.

In April 1967, WDAK moved to The Elms, an antebellum mansion at 1846 Buena Vista Road that was placed on the US Department of the Interior lists of historical sites in 1972.

During this entire period, WDAK was owned by the Woodall Family of Columbus, programmed Top 40, and was known as "Big Johnny Reb" or "The Giant of the Valley.
