WSB (now on RF 32), WUVG (RF 18) , WATC (RF 34), WHSG (RF 22) and WUPA (RF 36) all have done so, presumably. WPCH and WPXA will affect their changes on September 11. WPCH is taking over WPXA's RF 31 and WPXA is moving their RF to 16.
The only other station in the repack is WGTV, which will move its RF from 8 to 7 sometime next spring. The other Atlanta stations--WAGA, WXIA, WPBA, WGTA, WATL and WGCL--stay where they are as they chose not to participate in the spectrum auction.
