KZMP (1540 kHz) is a commercial AM radio station licensed to University Park, Texas, and serving the Dallas-Fort Worth Metroplex. It is owned by Estrella Media and airs a Classic Regional Mexican radio format. KZMP is currently operating under special temporary authority from the Federal Communications Commission at 100 watts, due to the sale of the land on which the 4 tower array broadcast. Current programming is temporally simulcast from co-owned 106.7 KZZA, while the facility, equipment, and license are being sold from Estrella Media to Richard Witkowski's North Texas Radio Group L.P. for $250,000. History This station signed on as KCUL in 1949, originally licensed to Fort Worth, Texas. KCUL was owned by East-West Broadcasting and featured a variety format through the 1950s. The station's call sign was chosen for investor A. B. Culbertson, although other sources mention a connection with Fort Worth-area optometrist L. H. Luck, because "K-C-U-L" was "Luck" spelled backwards. In the mid 1950s, KCUL switched to a country music format. Blocks of Spanish language programming were added in 1958 and the station became largely a Regional Mexican music outlet in the 1960s. By 1964, the radio station had picked up a sister station on the FM dial and hired Marcos Rodriguez, Sr. father of Marcos A. Rodriguez to be morning DJ and afternoon salesperson. At the time, FM radio in America was in its infancy. Listeners did not listen to FM very much and broadcasters weren't sure the technology was going to last. On New Year's Day, 1967, KCUL-AM-FM were sold by East-West Broadcasting to John Walton and was rebranded "Classical Country" KBUY, maintaining its Country format with Western music added. It became the first full-time Country/Western station in the Dallas/Fort Worth area; the format adjustment was described as "an 'uptown' version of its predecessor, KCUL." In 1976, the station again rebranded as KRXV (call sign derived from Roman numerals XV as "Radio 15"), this time with an All-News format that lasted for only 14 months. KRXV employed Marcos A. Rodriguez as a board operator and Jim Miklaszewski now an NBC News correspondent as News Director. Hal Eisner, currently a longtime TV newsman in Los Angeles, also worked at KRXV. The format then changed to beautiful music as "Radio 15," a joint operation between actor Jimmy Stewart and Oklahoma News Network owner William Schuller. In 1978, the call sign was changed to KMZK.
