The station signed on as a class A gospel station licensed to Jesup called WSOJ. In 1982, the station flipped (along with many others) to an audio simulcast of the new CNN Headline News. Shortly thereafter, the station went off the air. Gospel returned to the station in 1984, then country WAJS "The Great 98" a year later. Within a few months, the station became AC WZKS "Kiss FM". In 1989, the station's tower was moved to McIntosh County, closer to Savannah and began broadcasting oldies as "Oldies 98.3", and later "98.3 Cool FM."
In 2005, the station jumped on the JACK FM bandwagon and adopted an adult hits format. On March 16, 2007, the station dropped the JACK FM format and returned to the Oldies format once again, as "Oldies 98.3" after a 'protest' was held by then-former morning host Chuck "Boom Boom" Cannon asking for the return of Oldies 98.3. On September 24, 2007, WGCO adjusted to a Classic Hits format, playing a variety of songs from roughly 1964-1985, with the core being the 1970s. This transition also included a name change to "BIG 98.3."
On August 29th, 2013 the station dropped the classic hits format for a loop of Hank Williams Jr.’s “All My Rowdy Friends Are Coming Over Tonight”. Then, on Friday August 30th, WGCO relaunched its station as classic country as Envision Radio Networks "Hank FM" brand and rebranded as "98.3 Hank FM"
