KFUO-FM

KFUO-FM was a classical music radio station in St. Louis, located at 99.1 MHz FM. It was branded as "Classic 99 KFUO-FM". KFUO-FM transmitted with an effective radiated power of 100 kW. KFUO-FM was among the oldest FM stations west of the Mississippi River, broadcasting since 1948. KFUO-FM's studios were located on the campus of Concordia Seminary, one of two graduate theological seminaries operated by the Lutheran Church–Missouri Synod (LCMS). The station was owned by the LCMS, which still owns the KFUO AM radio station. KFUO-FM's transmitter was located in Affton, Missouri.

KFUO-FM began as a listener supported station, but moved to a commercial format several years ago.

KFUO-FM was voted best classical music station in America in 2005.

KFUO-FM was sold to Gateway Creative Broadcasting in March, 2010, and approved by the FCC in May. Classic 99 ended its 62-year classical music format at 10:00 PM on July 6, 2010 after playing Beethoven's Symphony No. 9. This also ended the remaining station in St. Louis devoted completely to classical music. The new owners launched a listener-supported Contemporary Christian music format branded as Joy FM on July 7, 2010 at 7:00 AM, despite a huge outcry by the local fine arts community to keep classical music alive in the area. A petition was filed with the FCC, alleging that the pending transfer was not open to public bidding. However, on May 7, 2010, the St. Louis Post-Dispatch reported that the FCC had approved the sale of KFUO-FM to Joy FM. The new call letters of 99.1 FM are KLJY.
