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.
KUHF
KUHF first began airing programs on November 6, 1950, at the 91.3 Megahertz frequency. The studios were located in the Ezekiel W. Cullen Building on the University of Houston campus. KUHT co-located with KUHF when the television station debuted in 1953. Broadcasting at 9,600 watts, the station was operated by student volunteers. In 1964, KUHF and KUHT moved to the former KNUZ-TV studios that were vacated by KTRK-TV a few years earlier. This studio would host both stations for the next 35 years, until the move across campus to the current Melcher Center for Public Broadcasting in 2000. The station increased its signal strength to 12,000 watts in 1969.
