KLJY (99.1 MHz) is a commercial-free, listener-supported FM radio station licensed to Clayton, Missouri, and serving Greater St. Louis.

The radio studios and offices are on Founders Lane in Des Peres, with a St. Louis address.

In addition to broadcasting music, the station also sponsors community events and activities around St.

Its transmitter is in Resurrection Cemetery in Shrewsbury, co-located with the towers for other St. Louis-area FM and TV stations.

"Joy FM" was founded by Sandi Brown, a former disc jockey on WCBW, a commercial Christian Contemporary station.

A new organization, Gateway Creative Broadcasting, was formed to look for a place on the FM dial for Christian Contemporary music.

A petition was filed with the FCC, alleging that the pending transfer was not open to public bidding, though it was unsuccessful.

[15] Ron Klemm, Dick Wobbe, and John Clayton, all formerly of KFUO-FM, continued the music ministry, which has grown since 2010.

Since April 2013, CLASSIC99.com has shared its music library of some 30,000 CDs with a new classical broadcast station in St. Louis branded as "RAF STL" and founded in part by former KFUO-FM program director Jim Connett.
