WMLB AM 1690, "The Voice of the Arts", is a radio station licensed to Avondale Estates, Georgia, and serves most of the metro Atlanta radio market. WMLB transmits on 1690 kHz with 10,000 watts daytime power and 1,000 watts at night. The station broadcasts an eclectic radio format, playing classical music, folk music, jazz, show tunes, comedy bits, classic country music and some rock and roll. WMLB's sister station is talk radio station WCFO AM, "News Talk 1160." The WMLB broadcast callsign was assigned to the station at 1160 kHz before being transferred to 1690 kHz in 2006 by its present owner JW Broadcasting.[2]


The radio station originally signed on with the callsign WSWK from the city of Adel in south Georgia, with a tourist information format in 2003, identifying as "Wild Adventures Radio" and simulcasting WDDQ FM of the same format.[3] The station was moved to the Atlanta radio market in 2004 when the license was transferred to serve the Avondale Estates community.[2] 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.[2] At that time, the station signed on in the Atlanta market with a country and western format,[4] but by September 2004 the station flipped radio formats to become a talk radio station and joined the Air America Radio radio network.[5] The format change came with a change to the WWAA callsign.[2]

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.[2] In June 2006, JW Broadcasting, owners of station WMLB (then assigned to 1160), took ownership of WWAA (formerly an Air America Radio network affiliate).[5] JW Broadcasting dropped the WWAA callsigns and then transferred the WMLB callsigns to 1690 kHz.[2] The callsign change brought with it the eclectic radio format previously heard on 1160. One radio program from the Air America Radio network remained on the station, The Al Franken Show, until Al Franken's last radio show in February 2007. The station continues airing several original programs including "Reflections on Flash Fiction" hosted by Professors Marshall Duke and Walter Reed of Emory University and Sidewalk Radio which is 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 Road in Atlanta and is now 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.
