KMPX (channel 29) is a television station licensed to Decatur, Texas, United States, serving the Dallas–Fort Worth metroplex as an affiliate of the Spanish-language Estrella TV network. It is owned by Tegna Inc. alongside Dallas-licensed ABC affiliate WFAA (channel 8). KMPX's offices are located on Gateway Drive in Irving, and its transmitter is located in Cedar Hill, Texas. Master control and most internal operations are based at the WFAA Communications Center Studios on Young Street in Downtown Dallas. KMPX is the largest primary Estrella TV affiliate by market size that is not owned and operated by the network's parent company Estrella Media, although it was previously owned by Estrella Media from 2004 until 2020. History Prior history of UHF channel 29 in Dallas–Fort Worth Channel 29 was originally allocated to Dallas, and two construction permits were issued for the channel. One was to be KLIF-TV, the television counterpart to radio station KLIF (1190 AM), owned by Gordon McLendon. A second attempt was made in 1962 to launch KAEI-TV on channel 29. Owned by and named for Automated Electronics Inc., the station would have broadcast printed quotes, news, and weather information. Since television sets were not required to include UHF tuners until the All-Channel Receiver Act went into effect in 1964, the company proposed to lease converters and UHF antennas to companies to install in their offices. Though the group hoped to be weeks away from signing the station on the air and gave dates of April 15 and June 1 for a planned sign-on, AEI never put it into service. The company's assets were acquired in late 1963. In 1966, three applicants filed to build new stations on channel 29—Grandview Broadcasting (which later took itself out of the running), Overmyer Communications, and Maxwell Electronics. In a successful bid to give both applicants a channel, Overmyer proposed changing out channel 29 for channels 27 and 33 at Dallas; Overmyer never built its station on channel 27, and Maxwell signed on KMEC-TV on channel 33 in October 1967. KMPX station history In 1985, three applicants vied for a license to operate a television station on channel 29, including the Wise County Messenger newspaper, owned by former WBAP-TV (channel 5, now KXAS-TV) anchor Roy Eaton, whose petition had resulted in the allocation to Decatur. After a settlement was reached, the construction permit was granted to Decatur Telecasting, owned by Charlotte, North Carolina, housewife
