KHON-TV
KHON-TV first signed on the air on December 15, 1952 as a primary NBC affiliate, KONA-TV, occupying the channel 11 position. It also had a secondary affiliation with DuMont (which it later shared with KULA-TV, now KITV, after it signed on in 1954) until its demise in 1955. The station, which is Hawaii's second-oldest television station (behind KGMB, originally on channel 9, now on channel 5), was originally owned by Herbert Richards. Two years later in 1954, the "Honolulu Advertiser" purchased the station. On October 16, 1955, KONA changed channels from 11 to 2 due to the lower VHF positions (2 to 6) having the most powerful ERPs at the time. The channel 11 frequency now belongs to PBS member station KHET. In 1956, KONA was sold to Pacific and Southern Broadcasting, the forerunner of Combined Communications. KAII signed on in 1958, with KHAW following in 1961. In 1965, the station's call letters were changed to the current KHON-TV.
KUBE-TV
The station first signed on the air on May 18, 1988 under the callsign KLTJ; it was founded by Eldred Thomas, who had earlier built radio station KVTT-FM (now KKXT) and television station KLTJ (now KSTR-TV) in Dallas. The station originally operated from studios located in Pasadena and a tower in Anahuac, and initially aired religious programs from a variety of sources, including the PTL Satellite Network, Christian Television Network and the Three Angels Broadcasting Network. The low-power signal and distance from Houston led to reception issues in the northern and western portions of the city; as a result, on May 18, 1989, Thomas moved the KLTJ programming and call letters to channel 22 on a tower based in Alvin. With the move of the KLTJ calls to channel 22, channel 57 changed its callsign to KRTW. It later changed its call letters to KVVV (a callsign formerly used on now-defunct channel 16 from 1968 to 1969) in 1994, when it switched to home shopping programming from Valuevision; it then became a FamilyNet affiliate as KAZH in 2000.
