Prior usage of channel 14 in Albuquerque

Channel 14 signed on as KGSW on May 8, 1981. The call sign was derived from the station's original owners, Galaxy Communications and Southwest Television. Initially, KGSW carried drama shows, movies from the 1940s through the 1970s, sitcoms, and religious shows. In the fall of 1983, the station added more sitcoms and began running cartoons in the 7–9 a.m. and the 3–5 p.m. weekday slots.

In 1984, the Providence Journal Company bought KGSW from the original owners. The station affiliated with the Fox network when it launched on October 9, 1986. The station continued a general entertainment format with cartoons, sitcoms, and movies. KGSW also carried a news capsule titled Fox 14 News Update. In the fall of 1992, after KKTO-TV (channel 2) went dark, Providence Journal acquired its programming and integrated it into KGSW's lineup. Shortly afterward, it acquired the KKTO license as well, and on April 5, 1993, KGSW moved to channel 2 and changed call letters to KASA-TV. The channel 14 license was then surrendered to the Federal Communications Commission (FCC) for cancellation.

As a Pax and UniMás station

In 1997, Paxson Communications was awarded a construction permit for a new station on channel 14; on April 8, 1999, it signed on as KAPX, airing programming from the family-oriented Pax TV (later i: Independent Television, now Ion Television) from 11 a.m. and 11 p.m., along with infomercials during the day and The Worship Network during the overnight hours. Pax would subsequently cut its programming hours from 4 to 11 p.m., and later 5 to 11 p.m., due to financial problems at Paxson. The company then chose to sell some of its stations, including KAPX; in 2003, Univision bought the station, and that June relaunched channel 14 as Telefutura (now UniMás) affiliate KTFQ. The network was previously seen in Albuquerque on KTFA-LP (channel 48), which switched to HSN. Programming from The Worship Network continued to air overnights on KTFQ for several years afterward.

2017 call sign and channel swap

On December 4, 2017, as part of a multi-market realignment, the programming and call signs of KTFQ and sister station KLUZ-TV were swapped: KTFQ and its UniMás programming moved to the Entravision-owned facility using digital channel 42 and virtual channel 41, while Univision's digital channel 22 and virtual channel 14 facility became the new home of KLUZ-TV.^[2]

Subchannels

The station's signal is multiplexed:

Analog-to-digital conversion

Because it was granted an original construction permit after the FCC finalized the DTV allotment plan on April 21, 1997,^[4] KTFQ-TV did not receive a companion channel for a digital television station. Instead, on June 12, 2009, which is the end of the digital TV conversion period for full-service stations, the station was required to turn off its analog signal and turn on its digital signal (called a "flash-cut"). KTFQ has been assigned channel 22 for its digital broadcast. Digital television receivers display the station's virtual channel as its former UHF analog channel 14.
