History.
WRKB-FM.
In September 1964, the station signed on as WRKB-FM, in Kannapolis, North Carolina. The station was owned by former WGTL Chief Engineer and Radio/TV Repair Shop owner Foy T. Hinson, who also served as General Manager and Chief Engineer.
Initially licensed with 3,000 watts on a tower, the station covered most of Cabarrus County, NC and Rowan County, NC, but little beyond. WRKB-FM was co-owned with WRKB 1460 AM, and simulcast the AM station's daytime-only operation, only separating from the AM station to carry high school sports in the evenings.
WRKB-FM's first studios were located at 101 West 1st Street in Kannapolis, on the second floor of a Jewelry Shop in a building owned by Cannon Mills. In 1967, the station built a tower and increased the FM power to 10,000 watts. The early format was Easy Listening and was programmed by Bob Lee. With the additional power and tower height, the station could be heard from Charlotte in the south to Lexington in the north.
Bill Hefner.
On weekday afternoons from 3 to 5 p.m., the station played Top 40 music, on a program called "Tunes For Teens." Early in 1969, Foy T. Hinson died from lung cancer, and his wife, Gertrude Hinson began to manage the station. Her management tenure was short-lived, and in 1971 the WRKB stations were sold to Southern Gospel singer Bill Hefner who partnered with Cabarrus County judge Robert L. Warren. 
Upon taking control of the stations, the operating hours of WRKB-FM were extended to 1 a.m. nightly and the stations launched a full-time country music format. Popular disc jockeys during this time were Randy Whitley, Kip Yates, Tracey Hudson, David Roberts, George Berry and Randy Turner, the latter of whom would return to the station 15 years later as Animal R. O'Boogie.
In 1972, the nighttime programming of WRKB-FM was changed to Southern Gospel music. Popular disc jockeys in this format included John Stiles, Jeannette Kenley and Sammy Oxendine.
On July 12, 1976, the stations relocated to a studio/transmitter complex at 910 Fairview Street in Kannapolis, and WRKB-FM began broadcasting in stereo. Less than a month later, the programming of the AM station was separated from that of the FM station. About a year later, the religious organization, The PTL Club, brokered the overnight hours on WRKB-FM, to make it a 24-hour operation.
AC and Top 40.
On May 15, 1982 the station began an Adult Contemporary format aimed at gaining new listeners in Charlotte. One month later, the station changed the call letters to WJZR. Downs Radio, Incorporated bought WJZR-FM in June 1983. 
New owner/General Manager Paul Downs extensively improved the station technically, and built out the station's existing construction permit for a power increase to 50,000 watts, significantly improving its coverage in Charlotte. Simultaneously with the August 1983 power increase, the format flipped from Adult Contemporary to Top 40. The station was then branded as Z-100.
Album rock.
In late 1985, the WJZR transmitter moved to a tower near Enochville, North Carolina in Rowan County, and the power increased to the legal maximum 100,000 watts. The station made the change to album-oriented rock under its current call letters WRFX, "99.7 The Fox", in 1986. Later that year, John Boy and Billy were hired as morning hosts. The show began airing nationally in 1993 out of WRFX's studios.
Over the years, the station's music has moved more in a classic rock direction. In 1996, the WRFX transmitter site moved again, this time to co-locate with WTVI's facilities in Charlotte.
Sports broadcasts.
In the early 2000s, WRFX became the flagship station of the NFL's Carolina Panthers. It picked up sports programming again from 2008 to 2011, simulcasting North Carolina Tar Heels basketball with formerly co-owned Sports radio station WFNZ to compensate for the latter's limited nighttime signal.
In 2011, WRFX joined the Performance Racing Network to carry NASCAR Sprint Cup Series races.
HD2 channel.
In August 2014, FM translator W254AZ 98.7 MHz began broadcasting a sports talk format from WRFX's digital subchannel. This station was a network affiliate of Fox Sports Radio, and was also heard on iHeartRadio. Jeff Kent was program director. The programming included Andy Furman and Mike North in the morning drive, Dan Patrick in the late morning and Steve Gorman in the afternoon.
On August 1, 2016, Martz Media Inc. began leasing the HD channel and translator, and flipped it to Spanish CHR as "Ke Buena 98.7".
At 8:00 p.m. on October 31, 2017, iHeartMedia re-assumed control of the HD2 channel and translator, and flipped the Spanish CHR format to an all-Christmas music format as "Christmas 98.7." On December 29, 2017, the station flipped to Contemporary Christian as "UP! 98.7". "Christmas 98.7" would return to W254AZ/WRFX-HD2 at the start of November for the 2018 and 2019 holiday seasons, with "UP! 98.7" returning after Christmas.
On June 29, 2020, fifteen iHeart stations in markets with large African American populations, including W254AZ/WRFX-HD2, began stunting with African American speeches, interspersed with messages such as "Our Voices Will Be Heard" and "Our side of the story is about to be told," with a new format slated to launch on June 30. That day, W254AZ/WRFX-HD2, along with the other fourteen stations, became the launch stations for the Black Information Network, an African American-oriented all-news network.
