KFDX-TV (channel 3) is a television station licensed to Wichita Falls, Texas, United States, serving as the NBC affiliate for the western Texoma area.

On May 19, 1951,[3] Wichtex Radio and Television—a locally based company managed under the direction of Darrold A. Cannan, Sr. and Howard Fry and the owner of KFDX (990 AM)—submitted an application to the Federal Communications Commission (FCC) for a construction permit to build and license to operate a broadcast television station in Wichita Falls that would transmit on VHF channel 3.

[14] Among the personalities who worked at KFDX-TV during the station's early years was Don Alexander—lead singer of rock-and-roll group Alexander and the Greats, and composer of the 1964 hit single "Hot Dang Mustang", which topped songs from such musicians as Elvis Presley, The Kinks, Frank Sinatra and The Rolling Stones to peak at #6 on the Billboard Top 100—who came to the television station in 1964.

[15] Nat Fleming, a local country and western bandleader, served as host of the self-titled, half-hour afternoon variety program The Nat Fleming Show on channel 3 from the station's inception in 1953 until the early 1960s, which featured a blend of musical performances (performed alongside bandmates Pee Wee Stewart, Elmer Lawrence, Buck White, Pappy Stapp and Tommy Bruce) and comedy skits.

[16][17][18] On July 30, 1970, Wichtex Radio and Television, then managed by Fry and Darrold A. Cannan Jr., sold KFDX to Charleston, West Virginia–based Clay Broadcasting Corporation for $5.05 million; the sale was approved on January 28, 1971.

Through the shared services agreement with KJTL, the station may also simulcast long-form severe weather coverage on channel 18 in the event that a tornado warning is issued for any county in its viewing area of southwestern Oklahoma and western north Texas.

Originally airing weekdays at 6:30 a.m., before the launch of a conventional morning newscast in the early 1990s eventually led to the program moving to a 5 a.m. slot as the latter program expanded, it was hosted for the majority of its existence by Joe Brown, who served as the station's farm director beginning in the early 1960s and also worked as farm editor for the Wichita Falls Times Record News.

During the late morning of April 3, 1964, a destructive tornado ripped through the City View section of northwestern Wichita Falls and neighboring Sheppard Air Force Base.

As rival KAUZ-TV interrupted regular programming that morning to show live footage of the tornado through a studio camera brought outside of channel 6's Seymour Highway studios, KFDX also moved one of its studio cameras outside its facility and pointed it toward the tornado—which initially appeared as a large, rotating dust cloud—as it approached the northwest portion of Wichita Falls, with Shaw and reporter Dee Fletcher providing commentary (sometimes interfered by line voltage and wind noise severe enough that cameramen positioned outside could not hear instructions warning viewers of the approaching tornado over their headphones).

[38] The 800-foot-wide (240 m) tornado (later retroactively rated as an F5 on the Fujita Scale) killed seven people, injured 111 others, and produced damage estimated at $15 million (with around 225 homes and businesses on the north side of town and at Sheppard AFB being reported destroyed).

[39][40] During the afternoon and evening of April 10, 1979, about 15 years after the City View twister, KFDX-TV provided complete coverage of an outbreak of tornadic thunderstorms that spawned several strong to violent tornadoes across northwest Texas and southwestern Oklahoma.

That evening's coverage culminated with the opening segment of the 6 p.m. edition of Newscenter 3, as chief meteorologist Bill Warren was relaying reports of a multiple-vortex tornado that was beginning its path of destruction across southern sections of Wichita Falls.

When the station came back on the air at 6:56 p.m. the following evening (April 11), KFDX provided 3+1⁄2 hours of continuous live coverage of the aftermath of the tornado.

[45] McBride's 31-year tenure—which lasted until his retirement on November 20, 2014—was surpassed only by that of Joe Brown for the longest-tenured television personality in the Wichita Falls-Lawton market; McBride was replaced as chief meteorologist by Kevin Selle (who joined KFDX/KJTL from Texas Cable News, where he previously served as chief meteorologist since the regional news channel's launch in 1998).

Following its sale to Mission Broadcasting and the formation of the SSA between the two stations, on September 20, 1999, KFDX began producing a half-hour newscast at 9 p.m. through a news share agreement with Fox affiliate KJTL; the program, titled Fox 18 News at 9:00, was the first local prime time newscast to debut in the market and originated from a secondary set at the KFDX/KJTL/KJBO studios on Seymour Highway in Wichita Falls.
