The station began broadcasting as a commercial operation on November 13, 1976, and held the call sign WQMT.

[1][3] On December 21, 2007, then-owners North Georgia Radio Group entered into an agreement to sell the station, still known as WQMT, to the Foundation For Public Broadcasting In Georgia, Inc., which shares the same street address as the GPB headquarters in Atlanta.

[5] Pending the sale, GPB reserved the call sign WNGH-FM for the station, to be assigned upon consummation.

The station switched from its previous classic country format (branded as "Georgia 99") to GPB programming on January 2, 2008, and later moved to the WNGH-TV tower around May 2008.

Effective June 30, 2016, the Foundation For Public Broadcasting in Georgia donated WNGH-FM to the Georgia Public Telecommunications Commission, the state entity that supervises GPB, making GPB the direct licensee.
