KSJN
Classical Minnesota Public Radio flagship station in the Minneapolis–St. Paul metropolitan area
KSJN (99.5 FM) is a non-commercial educational radio station licensed to Minneapolis, Minnesota. Owned by Minnesota Public Radio (MPR), this station serves the Twin Cities region as the flagship of "YourClassical MPR", MPR's classical music network. KSJN's studios are located at the MPR Broadcast Center on Cedar Street in downtown Saint Paul, while its transmitter is located on the KMSP Tower in Shoreview. KSJN broadcasts using HD Radio technology, and uses its HD2 subchannel to carry American Public Media's Classical 24 network.
The 99.5 frequency was established as commercial radio station WLOL-FM in 1957; the station achieved its most success as a top-rated Top 40 station during the 1980s under Emmis Communications ownership. After Emmis purchased the Seattle Mariners baseball club, the company sold WLOL to MPR in 1991. Relaunched as KSJN, the station has originated the public radio service's classical format full-time ever since.
History
Classical and easy listening
On July 18, 1956, radio station WLOL (1330 AM) was granted a construction permit for a new FM radio station to be heard on 99.5 MHz. The station, WLOL-FM, began broadcasting in February 1957 with a classical music format. The station maintained this programming for its first 16 years of operation until the money-losing outlet switched to automated beautiful music in August 1973.
