WCLK
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. WCLK is also broadcast in HD radio.
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.
