WARH

On November 24, 1965, WGNU-FM first signed on.[4] It was the FM counterpart of AM 920 WGNU, under the ownership of Chuck Norman. Both stations simulcast a country music format for Granite City and its surrounding communities. Norman sold the FM station to Doubleday Broadcasting in 1977. Doubleday boosted the station's signal to cover most of the St. Louis radio market. The call sign was changed to WWWK, with the station simulcasting the album oriented rock (AOR) format of AM 1380 KWK (now KXFN).[5] The stations called themselves "Stereo WK."

In November 1986, the two stations were bought by Chase Broadcasting. The simulcast ended in 1987, with AM 1380 becoming Oldies WGLD, while FM 106.5 (now with the call sign KWK-FM) moved to a Top 40/Hot AC format.

In 1988, KWK-FM became WKBQ-FM, retaining the Top 40/Hot AC format but switching to the handle "Q106.5." In September 1991, WKBQ-FM brought the morning team of "Steve & DC" to St. Louis from Birmingham, Alabama. In 1993, "Steve & DC" and WKBQ-FM would face controversy over comments made during the May 10th morning show and was the subject of much local news coverage for weeks. Also in 1993, WKBQ-FM again was simulcast on AM 1380.

In late 1993, WKBQ-FM was purchased by Zimmer Radio Group of Cape Girardeau, Missouri. On January 20, 1994, it switched dial positions with sister station 104.1 FM WKKX (currently WHHL), which had a country format known as "Kix 104" (with the AM simulcast also moving with the swap).[6][7] The station became "New Country Kix 106.5," with the popular morning duo "Steve & DC" heard for the second time on the 106.5 MHz frequency. That led to the team scoring its biggest ratings in St. Louis. The "Steve & DC" morning show consistently ranked #1 in the all-important Persons 18-49 and Persons 25-54 demographics on WKKX.

In November 1996, Emmis Broadcasting bought Kix 106.5. But in 2000, Emmis swapped WKKX to Bonneville International Broadcasting for Los Angeles country music station KZLA (now KLLI). At 12:00 a.m. on October 4, 2000, the first day Bonneville owned the station, it changed call letters to WSSM and adopted a Smooth Jazz format as "Smooth 106.5" (later "106.5 Smooth Jazz").[8] The Smooth Jazz format lasted five years.

On April 10, 2005, after playing "Thank You" by Euge Groove, the station adopted its current adult hits format, branded as "106.5 The Arch." The first song on "The Arch" was "Roll With the Changes" by REO Speedwagon.[9] The station adopted its current WARH call letters on April 18. WARH was initially programmed by Jules Riley. The Program Director since 2016 is Scott Roddy, who also serves as the P.D. for sister station 92.3 WIL-FM.

On January 19, 2011, Bonneville announced the sale of WARH, as well as 16 other stations in four markets (St. Louis, Chicago, Cincinnati and Washington, D.C.), to Minneapolis-based Hubbard Broadcasting.[10] The sale was completed on April 29, 2011.[11] Hubbard has kept the adult hits format in place, which continues as one of St. Louis' top ten stations.
