The call sign was changed to WWWK, with the station simulcasting the album oriented rock (AOR) format of KWK (1380 AM, now KXFN).

The simulcast ended in 1987, with AM 1380 flipping to oldies as KGLD, while FM 106.5 (now with the call sign KWK-FM) moved to a Top 40/CHR format.

In September 1991, WKBQ-FM brought the morning team of "Steve & DC" to St. Louis from Birmingham, Alabama.

The following year, they aired an interview with a woman accusing a local broadcaster of harassing her, which may have contributed to his death by suicide in a small plane crash.

[9][10] 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.

[12] In 2000, Emmis swapped WKKX to Bonneville International for Los Angeles country music station KZLA (now KLLI).

[13][14][15][16] 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."

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.
