The station was originally owned by Big Country of Missouri, Inc., and was issued the KBHO call sign on July 17, 1998.[1] The KWRT-FM call sign was assigned on June 14, 2000,[2] and coincided with a format change to adult standards as "Casino 93.1." Casino 93.1 was originally simulcast on then-sister station KWRT-AM, and featured the Jones Radio Network's "Music of Your Life" satellite feed.[3]
2005-present: Adult Hits
In October 2005, the station dropped adult standards in favor of the ABC Satellite Network's Jack FM feed.[4] In January 2011, Billings Broadcasting LLC purchased KWJK.
The station airs a local talk show in the morning, The Tom Bradley Show. This is rare for a Jack FM station. The rest of the day runs without DJs.
