KTLK-FM (104.9 MHz) is a commercial FM radio station licensed to Columbia, Illinois, and serving Greater St. Louis.

The transmitter is in the Resurrection Cemetery in Shrewsbury, amid the towers for other St. Louis FM and TV stations.

[2] The HD-2 digital subchannel carries the urban adult contemporary format previously heard on the main channel, known as "Majic 104.9".

After a local morning drive time show hosted by Jamie Allman, the rest of the weekday schedule is made up of nationally syndicated programs, mostly from co-owned Premiere Networks: Glenn Beck, Clay Travis and Buck Sexton, Sean Hannity and Jesse Kelly, as well as Dave Ramsey and "Red Eye Radio".

In 1997, the station was sold to Jacor Broadcasting, who also owned urban powerhouse KMJM, “Majic 108”, which was then at 107.7 FM.

On November 7, 2012, at 9 a.m., KMJM-FM and its urban AC format moved to 100.3 FM (ironically, KATZ-FM's former frequency), replacing classic rock-formatted KBWX ("The Brew").

On October 18, at Noon, after playing "2 On" by Tinashe, followed by a commercial break, KBWX flipped to alternative rock as "ALT 104-9".

The station gave a St. Louis affiliate to a number of Premiere Networks talk shows, whose parent company is iHeartMedia.
