Overview
KTFF-DT is a full-power television station licensed to Porterville, California, and serving the Fresno–Visalia television market. The station broadcasts Spanish-language programming from UniMás, the secondary U.S. television network associated with TelevisaUnivision. Although its license city is Porterville, KTFF-DT operates alongside Univision station KFTV-DT from the Univision Fresno Broadcast Center on Univision Plaza in northwestern Fresno. Its main transmitter is located on Blue Ridge in rural northwestern Tulare County, allowing the station to cover a broad portion of the Central Valley market. The station began broadcasting on May 6, 1992, under the call sign KKAK. It initially operated as an independent outlet with a schedule consisting largely of infomercials, religious programs, and home-shopping content. In 1994, its call letters changed to KKAG. Paxson Communications acquired the station in 1998, and on August 31 of that year it became an owned-and-operated outlet of Pax TV, Paxson's family-oriented television network, under the new call sign KPXF. Univision Communications acquired the station from Paxson in 2003. The transaction created a duopoly with KFTV-DT, the company's Univision affiliate in the market. Following the completion of the sale, the station adopted the KTFF call letters and became an owned-and-operated station of TeleFutura, Univision's secondary network. TeleFutura was relaunched as UniMás on February 7, 2013, and KTFF-DT has subsequently carried UniMás programming as its primary service. KTFF-DT's coverage is supplemented by KTFF-LD, a low-power translator serving the northern part of the market from a transmitter near Bald Mountain and Meadow Lakes. The station's programming is also simulcast in high definition on KFTV-DT's sixth digital subchannel, channel 21.6, from a separate transmitter site. These relay arrangements extend the UniMás service beyond the station's primary over-the-air footprint. The station participated in the United States digital television transition. Its analog signal on UHF channel 61 ended on June 12, 2009, while its digital signal initially operated on UHF channel 48 and retained virtual channel 61. As part of the FCC's post-spectrum-auction repack, KTFF-DT was assigned to move its digital transmission to UHF channel 23. The FCC licensed the station for channel 23 operation on December 20, 2018. KTFF-DT is principally a distribution outlet for UniMás rather than an independently branded national media company. Its identity is therefore tied to local broadcast service, Spanish-language network programming, shared technical and operational infrastructure with KFTV-DT, and TelevisaUnivision's broader Central Valley television presence. Publicly documented information does not establish a separate corporate headquarters, independent executive team, or standalone financial reporting for the station.
History
KTFF-DT signed on May 6, 1992, as KKAK, a Porterville-licensed independent station. Its original schedule relied on infomercials, religious programming, and home-shopping content rather than a major network affiliation. The station became KKAG in 1994. Paxson Communications acquired KKAG in 1998. On August 31 of that year, the station joined Pax TV as an owned-and-operated outlet and changed its call sign to KPXF. Pax TV was designed as a family-oriented network, giving the station a more defined network role than it had held as an independent broadcaster. In 2003, Univision Communications purchased KPXF from Paxson. The acquisition gave Univision a second full-power station in the Fresno market alongside KFTV-DT, its Univision outlet, and established a local duopoly. After the transaction, the station's call letters became KTFF and its affiliation changed to TeleFutura, Univision's secondary Spanish-language network. A 2007 FCC order addressed the regulatory history of the sale and denied a request for review. The order also implemented an arrangement involving Christian Network, Inc., the parent of The Worship Network. Under the arrangement, CNI received rights to program KTFF during overnight hours from 1 a.m. to 6 a.m. and could receive exclusive use of a digital subchannel if specified technical and operational conditions were met. Later publicly available station information indicated that KTFF was carrying UniMás programming full-time by 2014, although the exact date on which The Worship Network carriage ended is not established. Univision later acquired low-power station KAJA-LP from Cocola Broadcasting and repurposed it as a fill-in translator for KTFF. The translator adopted the KTFF-LD call letters and served the northern portion of the Fresno market. KTFF programming has also been distributed in high definition through KFTV-DT's sixth digital subchannel, channel 21.6. KTFF's main transmitter is located on Blue Ridge in rural northwestern Tulare County, while the translator uses a site near Bald Mountain and Meadow Lakes. The station's analog service on UHF channel 61 ended on June 12, 2009, during the nationwide U.S. digital television transition. Its digital operation initially used UHF channel 48 while continuing to identify through virtual channel 61. The FCC's spectrum-auction repack subsequently required KTFF-DT to move its physical digital allocation to UHF channel 23. The FCC licensed the channel-23 operation on December 20, 2018. Today KTFF-DT functions as TelevisaUnivision's UniMás station for the Fresno–Visalia area. Its operations are integrated with KFTV-DT at the Univision Fresno Broadcast Center in Fresno, and its service is extended through a low-power translator and a KFTV digital simulcast. The station's documented history is primarily one of ownership changes, network realignment, regulatory transition, and technical expansion rather than independent local corporate activity.
