The radio station originally signed on with the call sign WSWK from the city of Adel in south Georgia, with a tourist information format in 2003, identifying as "Wild Adventures Radio" and simulcasting FM 92.1 WDDQ with the same format. The station was moved to the Atlanta radio market in 2004 when the license was transferred to serve Avondale Estates. When the station was moved to the Atlanta area, its radio transmitter was co-located with station WATB's transmitter and WSWK's signal was diplexed on to one of WATB's antenna towers. At that time, the station signed on in the Atlanta market with a country music format. But by September 2004 the station flipped radio formats to become a talk radio station and joined the Air America Radioprogressive talk radio network. The format change came with a change to the WWAA callsign. formerly used by WMLB from 2006 until 2013. Later in 2004, the station's transmitter was moved to a new dedicated facility off of Cheshire Bridge Road in Atlanta with a new single-tower antenna. In June 2006, JW Broadcasting, owners of station WMLB, took ownership of WWAA. JW Broadcasting dropped the WWAA call letters and then transferred the WMLB call sign to 1690 kHz. The change brought with it the eclectic radio format previously heard on 1160. One radio program from the Air America network remained on the station, The Al Franken Show, until Al Franken's last radio show in February 2007. The station continued airing several original programs including "Reflections on Flash Fiction," hosted by Professors Marshall Duke and Walter Reed of Emory University, and Sidewalk Radio, hosted by local entrepreneur and real estate agent Gene Kansas. In early February 2013, WMLB moved its transmitter location a few hundred feet away across Cheshire Bridge in Atlanta. This transmitter is co-located with WNIV and WAFS, with all three stations sharing the same single vertical broadcast antenna tower. The single broadcasting antenna tower, which WMLB used exclusively from 2006 until 2013, was dismantled. The station went off the air early morning May 14, 2018, after the studio lease ended. JW Broadcasting will continue to own the broadcast tower. As of this writing, WMLB has been on the air for several weeks, playing oldies music and old interviews.
