WCLK FM 91.9 is a radio station licensed to Atlanta, Georgia, USA, and serves the core area of metro Atlanta. It is owned and operated as a public radio station by Clark Atlanta University.[2][3] WCLK is also broadcast in HD radio.[4]

It was granted a construction permit in early 2009 to downgrade its effective radiated power (the maximum in any direction) from 6 kW to 2.5 kW; however, this will change its footprint very little, reducing its range to the north and east by just a few kilometers or miles. Coverage to the south and west will remain the same.

WCLK airs some NPR talk programming not heard on WABE, such as The Takeaway, due to WABE's mostly classical format where little talk programming is aired aside from their HD channel.

Translators

WCLK has been relayed by two broadcast translators, whose rangess were entirely within its main broadcast area. Its former six-watt translator W250BC 97.9 in Riverdale was sold for $100,000 to Extreme Media Group in November 2007, then to commercial broadcaster Cumulus Broadcasting in February 2009. It now airs 99X from WNNX-FM FM 100.5 HD Radio channel 2, also owned by Cumulus. WCLK was then relayed by W275BK in Decatur, which was 170 watts on 102.9, and remained owned by Radio Assist Ministry, which owns dozens of translators across the country. In April 2009, that station briefly became "Streetz 102.9", a WWVA-FM 105.7 HD radio channel, until the person in charge was sued by former employer Radio One. Although translators are prohibited from airing their own programming, both stations operate through a loophole that allows them to do so if it is also simulcast on the primary station's HD radio channels.

The station has applications pending from 2003 for five new translator stations: Fayetteville. Stone Mountain, East Point, and Stockbridge on 94.5, and Kennesaw on 98.9.[5]

WCLK collaborated with the City of Atlanta to create the Jazz of the City Atlanta portrait featuring over 100 jazz musicians surrounding Mayor Shirley Franklin in the Atlanta City Hall Atrium. The color photograph by Seve "Obasina" Adigun and Gregory Turner taken in April 2007 mirrors the iconic, classic, black-and-white image, A Great Day in Harlem 1958 by Art Kane.
