The call sign stands for Cherokee, the county of which Canton is the seat of government, largest city, and geographic center.

Among the personalities were station manager Byron Dobbs (retired in 1997), Mike McDougal, and Jim Axel (who moved to WAGA-TV).

Because WCHK was on the AM band with a daytime-only operation, it was required to sign-off by sunset, allowing clear-channel stations to take over the airwaves.

WCHK-FM was bought by Clear Channel Communications (now iHeartMedia) in 1993, under a local marketing agreement, simulcasting news/talk station WGST as WGST-FM.

[5] On November 14, 2006, Davis Broadcasting, owners of WLKQ-FM 102.3 in Buford, made the purchase of both WCHK and sister station WNSY-FM, being completed in January 2007.

WNSY returned to the airwaves on February 1, 2007 as a simulcast of WLKQ-FM (La Raza 102.3), broadcasting a Regional Mexican format.

In 2013, WCHK switched from Mexican music to a simulcast of W243CE Winder, airing a Spanish Tropical format as La Mega 96.5.

On March 21, 2017, WCHK re-added W243CE as a simulcast and relaunched the Latin pop format as La Nueva Mega 96.5/1290.
