KTNF is a radio station licensed to St. Louis Park, Minnesota, and serving the Minneapolis-St. Paul metropolitan area. The station brands itself as "The Progressive Voice of Minnesota," and offers a combination of locally produced and nationally syndicated progressive talk programming. KTNF's studios and transmitter are located in Eden Prairie.
In the summer of 2004, the station was purchased by Janet Robert, former Democratic-Farmer-Labor candidate for the US House of Representatives, to provide a local outlet for syndicated programming from the former Air America Radio network (the station was originally known as "Air America Minnesota"). KTNF also carries shows from Dial Global.
The station signed on as KRSI in 1958, with studios located at 4500 Excelsior Blvd. in St. Louis Park. In 1967, it started an FM station at 104.1 MHz, which, following many format changes, is now KZJK. At one point, both stations were owned by Red Owl Stores. In October 1972, the two stations moved to what is now the AM station's current studio and transmitter facility in Eden Prairie.
The 950 AM frequency has been home to many formats. KRSI was one of the first Top-40 stations in the Twin Cities in the late 1950s. In its most popular incarnation, from 1968 to 1972, it was simulcasting with KRSI-FM (104.1) as "all request radio".
Over the years the station has been through many formats, including:
