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.
KTVQ (Oklahoma City)
KTVQ was the first television station to sign on in Oklahoma City since the Federal Communications Commission-imposed freeze on television broadcast licenses was lifted in 1953. KTVQ was the first of three commercial television station to sign on in the Oklahoma City market during 1953: another UHF station, KLPR-TV (channel 19, later KMPT; allocation now occupied by Cornerstone Television affiliate KUOT-CD), debuted as a DuMont Television Network affiliate on November 8; KWTV (channel 9) launched as a CBS affiliate on December 20. As with many early UHF stations, reception of KTVQ required television set owners to purchase a standalone UHF tuning adapter. (Set manufacturers were not required to equip televisions with UHF tuners until the Congress passed the All-Channel Receiver Act in 1961, with UHF tuners not included on all newer sets until 1964.) The station conducted a series of promotions to encourage converter adoption including events indended for electronics dealers as well as radio and television commercials directed at the general public.
