In addition to a standard analog transmission, WZGC broadcasts over one HD Radio channel, and is available online via Audacy.

WQXI and WGST (920 AM) were the leading top 40 stations in Atlanta, but as FM listening increased, WZGC gained an audience.

Then, in 1986, WAPW (99.7 FM) debuted with its own popular top 40 format, with WZGC's ratings declining as a result.

The name change to "Dave FM" and format switch to adult album alternative (AAA) came at 5 pm on July 21, 2004, following a stunt featuring all-Dave Matthews Band music.

At the same time, CBS had enjoyed success with several of its FM stations that had switched to all sports formats in Dallas, Boston, Detroit and Pittsburgh.

[11][12][13] Dave's final day of programming, which started on September 29, after a three-day radiothon for Children's Healthcare of Atlanta, consisted of the on-air staff hosting final shifts (including Steve Craig, Jill, Mara Davis, Charles, Yvonne Monet, Sully, Renee and Margot), as well as a "Top 92 Songs of Dave FM" countdown.

Around 12:20 am on September 30, Dave FM ended regular programming with "Little Lion Man" by Mumford & Sons (the #1 song in the countdown) and "Atlanta" by Butch Walker.
