KMNV (1400 kHz "La Raza") is a commercial AM radio station licensed to St. Paul, Minnesota, and serving the Twin Cities radio market. It is owned by Santamaria Broadcasting and broadcasts a Spanish-language radio format featuring Regional Mexican music with some weekday comedy shows. KMNV's radio studios and offices are in Richfield. KMNV is powered at 1,000 watts non-directional. The transmitter is near the Mississippi River in St. Paul. Programming is also heard on FM translator K239CJ at 95.7 MHz in St. Paul. History WMIN The station signed on the air in the summer of 1936, when St. Paul furniture retailer Edward Hoffman began broadcasting at 1370 kHz. WMIN was reassigned to the 1400 kHz frequency in 1941 when the North American Regional Broadcasting Agreement treaty (NARBA) was negotiated to reduce interference between American radio stations and those from other countries. Noted jazz announcer Leigh Kamman started his career in broadcasting at the station around this time. For many years, the station's transmitter and single tower have enjoyed an enviable location in the center of the metro area. Since at least the late 1970s/early 1980s, the station's technical plant has been located within a block of the city limits separating Minneapolis and St. Paul just east of the Mississippi River at 611 West Frontenac Place in St. Paul. It is plainly visible to travelers on Interstate Highway 94. The studios, at least in the 1970s and 1980s, were also located at this address. Moving into FM, TV WMIN set up a sister station, WMIN-FM at 99.5 MHz in 1945, which operated until being purchased by the owners of AM station WLOL and took the WLOL-FM call letters in 1956. WMIN eventually signed on another FM sister station, at 102.1 MHz. In addition to FM, WMIN went into television as well, applying for a television license in 1952 for Channel 11. WTCN radio had also applied for this frequency, so the stations arranged to divide the broadcast day between them. The stations soon merged as WTCN, which eventually became today's KARE. In 1954, the call sign for 1400 AM briefly changed to WMNS, reflecting a change to a full service format of adult popular music, news and sports. The format remained, but the station returned to being WMIN later that year. As WDGY, WLOL and KDWB enjoyed success playing Top 40 music in the late 1950s, WMIN joined the fray. In
