The station's studios and offices located at the Peachtree Palisades Building in the Brookwood Hills district.

The transmitter site is off Joseph E. Boone Boulevard Northwest in the Center Hill neighborhood of Atlanta.

He stayed at WGST until Roger Ailes offered Hannity a position on the soon-to-debut Fox News Channel in 1996.

During his time at WGST, he was given the nickname "Hanni-Pie, The Tin Man" by fellow host Kim Peterson.

WGST was the station that carried Sid Bream's winning slide in Game Seven of the 1992 NLCS.

In May 1994, the station was outbid for Braves broadcast rights by WSB, which previously had carried the games from 1966 until 1991.

To remedy the situation, WGST’s sister station WKLS (96.1 FM, now WWPW) began simulcasting Braves games.

"The Morning Drive" was briefly hosted by comedian Mike Stiles from July 13 to 24, 2009, before being replaced by syndicated shows.

The weekday lineup was The Rob & Dave Show at 6 a.m., Glenn Beck at 9 a.m., Rush Limbaugh at noon, a local version of The Rusty Humphries Show at 3 p.m., Mark Levin at 6 p.m., Michael Savage at 9 p.m., George Noory at midnight and The Wall Street Journal report at 5 a.m. On September 26, 2012, several Atlanta news outlets reported that WGST would be changing formats.

[6] Coincidentally, Michael Savage suspended the broadcast of his show around the same time due to a contract dispute with his syndicator.

On April 23, 2013, less than eight months after switching to Spanish-language sports, WGST announced it would return to an English-language talk format beginning June 3, 2013, featuring a lineup consisting entirely of syndicated programs, including Bloomberg's First Word with Ken Prewitt, America's First News with Gordon Deal, Glenn Beck, Michael Berry, and Coast to Coast AM among others.

ESPN Deportes Radio moved to the FM translator 92.3 W222AF, replacing an all-comedy format.

On August 30, 2019, WGST flipped to conservative talk as 640 Fox News Radio with a revised lineup.
