WKVG is north western South Carolina's primary entry point station for the Emergency Alert System.

In 1963, WMUU-FM became one of the most powerful FM stations in South Carolina, radiating 100,000 watts and increasing its listening radius from fifty to a hundred miles.

Bob Jones University also bought WAVO 1420 AM in Atlanta but later sold it in order to focus on the Greenville station.

[4] WMUU-AM-FM eventually moved to 920 Wade Hampton Boulevard, and BJU transferred ownership of the station to the Gospel Fellowship Association, its missionary arm, headquartered in the same building.

On August 24, 2012, Bob Jones III announced the sale of WMUU-FM to Salem Communications, co-founded by BJU graduate Stuart Epperson.

[8] Programming included a local news and call-in show hosted by Joey Hudson, later known as The Morning Answer.

The rest of the schedule was nationally syndicated conservative talk, mostly from the co-owned Salem Radio Network, hosted by Mike Gallagher, Dennis Prager, Charlie Kirk, Brandon Tatum and Sebastian Gorka, and others.

On August 23, 2023, an FCC filing disclosed that Salem would sell WGTK-FM, along with WRTH and WLTE, to the Educational Media Foundation for $6.775 million.

[13] WKVG's HD4 subchannel broadcast a Regional Mexican format branded as "Poder 102.9" and fed FM translator W275BJ at 102.9 MHz in Greenville until November 2023.
