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.
KLKN
Channel 8 was originally licensed to Albion, Nebraska, and began broadcasting December 3, 1964 as KHQL-TV, a satellite of KHOL-TV (channel 13, now KHGI-TV) in Kearney and the Nebraska Television Network (NTN, later known as NTV) owned by Bi-States Company. The station served as the ABC affiliate for much of the Nebraska side of the Sioux City, Iowa market. NTV Enterprises acquired the NTV stations in 1974; on June 4, the station's call letters were changed to KCNA-TV (for the largest towns in its service area, Columbus, Norfolk, and Albion).
