KUDF-LP is a low-power television station located in Tucson, Arizona. It is owned by LM Media Group, Inc., a local company headed by Rodolfo Velez Gonzalez, and is an affiliate of Azteca America. The station's license authorizes an analog broadcast on UHF channel 14 from its transmitter on Mount Bigelow, however, by Special Temporary Authority from the FCC, granted November 15, 2012, the station broadcasts in digital. It is carried on the major cable television systems in Tucson.
An original construction permit for a low-power television station on channel 14 was granted to K. Sandoval Burke on February 28, 1989. The station, K14HR, was constructed in three months and was licensed on May 31, 1989. In August 1990, Hispanic Broadcasters of Tucson, Inc. bought the station. They ran it as a sister station to KHRR under the call letters KFAM and a family-oriented format. KFAM aired such shows as The 700 Club, kids shows, other religious shows, sports specials, and pet shows. The station had no cable carriage, and shows soon moved to stations that were on cable: "Shepherd's Chapel", for instance, moved to KTTU. In April 1996, it relaunched under the call letters KQBN-LP, meaning Que BieN, aiming to target upper-income Hispanic households.. The station was described as "like CNN in the daytime and HBO in primetime", showing news from Telenoticias (now Telemundo Internacional) in the day, uncut Spanish-language movies in the evening, and novelas at other times. Among launch programs included the soap opera "Las Aguas Mansas" between the newscasts from 8 to 9pm.
Hispanic Broadcasters of Tucson sold the station to Television Apogeo de Tucson in October 1998. By 2002, the station was broadcasting programming from Telemax, a network of stations rebroadcasting XEWH-TV in Hermosillo, Sonora, Mexico. In January 2004, Una Vez Mas bought the station from Television Apogeo de Tucson and changed the call letters to KUDF-LP, intending to switch to Azteca America. However, the station went silent, and was not seen on air until November 2005, when they began broadcasting Azteca America programming.
Although Una Vez Mas replaced the call letters when they took control of operations in January 2004, KQBN-LP has since been assigned to two other Una Vez Mas stations — Phoenix channel 43 took the call letters in March 2005, then when they sold the station the following November, Una Vez Mas transferred the KQBN-LP call letters to Prescott channel 28.
