In 1965, Maxwell Electronics Corporation applied for a new television station on channel 29 in Dallas, which placed it into comparative hearing with two other applicants: Overmyer Communications and Grandview Broadcasting Company.

[7] Dallas Cowboys defensive tackle and future Pro Football Hall of Fame member Bob Lilly also hosted a weekly half-hour program.

[10] Evans was on the hunt for dark UHF television stations nationwide: in addition to the purchase of KMEC, for $40,000 plus the assumption of more than $170,000 in liabilities, he owned the construction permit for KDNL-TV in St. Louis and made moves to acquire other unbuilt outlets in several eastern states.

[11] The Maxwell brothers would later make claims that the newspapers in the Dallas–Fort Worth area—the Dallas Times Herald, the Dallas Morning News and the Fort Worth Star-Telegram—relegated UHF station listings to inferior coverage and did not print them at all on Sundays, challenging the license renewals of their associated broadcast stations in the market; the newspapers did not give UHF listings equal prominence until 1969, by which time KFWT-TV and KMEC-TV had both fallen silent.

Station president Warren Litzman[19] anchored Newsday, a two-hour midday program covering news events with a particular emphasis on the Mid-Cities area.

[19] On weekday evenings, the station aired Tempo '72, a live teen show, and Club 33, a 90-minute talk and variety hour helmed by vice president Bob Dawkins.

Much like its sister stations—WYAH-TV in Portsmouth, Virginia and WHAE-TV in Atlanta—the new KXTX-TV aired a lineup of general entertainment fare during the daytime and early evening and shifting to religious shows, including CBN's own The 700 Club, in prime time and on Sundays.

Doubleday Broadcasting—the owner of the other UHF station in Dallas, KDTV—announced in June that it was seeking to donate the facility to a nonprofit organization after a failed sale and years of financial losses.

[27] Sheldon K. Turner, who had previously been the general manager of KDTV, along with two other principals, filed in September 1974 as the National Business Network to build a new channel 33 TV station in Dallas.
