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.
KXAN-TV
The station first signed on the air on February 12, 1965, as KHFI-TV, broadcasting on UHF channel 42. It was owned by the Kingsbury family, along with KHFI radio (970 AM, now KTSN at 1490; and 98.3 FM, now KVET-FM at 98.1). KHFI was the second television station in Austin, signing on a little more than twelve years after KTBC-TV (channel 7). Although Austin was big enough to support three television stations as early as the 1950s, KTBC was the only VHF license in the area. Until 1964, UHF stations could only be seen with an expensive converter, and even then picture quality left much to be desired. Additionally, UHF signals usually do not travel very far over long distances or over rugged terrain. This made several potential owners skittish about the prospects for UHF in a market that stretched from Mason in the west to La Grange in the east, and also included much of the Hill Country.
