KXBS (95.5 FM) is a non-commercial, listener-supported radio station licensed to Bethalto, Illinois, and serving Greater St. Louis.

KXBS and sister station KQBS 97.7 in Potosi, Missouri are owned by Gateway Creative Broadcasting, and they simulcast a Christian rhythmic contemporary radio format known as "Boost 95.5".

The radio studios for KXBS, KQBS and Christian Contemporary KLJY are on Manchester Road (Missouri Route 100) in Des Peres.

The station signed on in 1987, as WXJO, airing an adult standards format, and broadcast with 6,000 watts, a quarter of its current power.

[4] Inadequate advertisement revenues, combined with a pending lawsuit from the original trademark holder of the name The Imagination Station, forced Cox into a position where he could not maintain the lease on the transmitter.

Shortly after longtime rival KMJM-FM flipped to classic hip-hop in November 2014, WFUN dropped the "Old School" moniker and simply started calling itself "95.5".

[7] On November 5, 2020, Urban One announced that it would trade WHHL and the intellectual property of WFUN-FM, as well as two other stations in Philadelphia and Washington, D.C., to Entercom.

The following day, Urban One announced it would divest WFUN-FM to Gateway Creative Broadcasting, owner of contemporary Christian-formatted KLJY.

The group would take over WFUN-FM under a local marketing agreement (LMA) on January 4, 2021, and flip the station to Christian rhythmic CHR as Boost Radio (in simulcast with KQBS).

From November 23, 2020 through December 15, 2020, KXBS ran a four-minute loop produced by Urban One, directing listeners to 96.3 to hear WFUN-FM.
