An original construction permit for low-power television station K64DR (channel 64) was granted to Broadcasting Systems, Inc. on August 23, 1989.
In December 1990, the station was sold to Hispanic Broadcasters of Arizona, Inc., which owned Tucson Telemundo affiliate "KHR" (later KHRR).
In October 1997, KDRX-LP added a Spanish-language newscast produced locally by ABC affiliate KNXV-TV (channel 15).
[6] The station began producing its own newscast a few years later after moving into KNXV's former Phoenix studio facility.
[7] The station was sold to Apogeo Television Phoenix LLC in 1999[8] and moved to channel 48 in 2000, improving over-the-air reception.
The request involved not only a swap of licenses but also non-commercial reservations in Phoenix and Holbrook, plus the two low-powered stations (KPHZ-LP on channel 58—later KDTP-LP—would be added to the deal later); in October 2005, the FCC agreed to the proposal, over the objection of Univision, citing the compelling public interest benefit of equal competition in Spanish-language television in Phoenix.
