applied for the channel 26 allocation in 1978 under the umbrella name Mauna Kea Broadcasting Company. KSHO signed on the air December 23, 1982 as Hawaii's first television station operating on the UHF band. Originally operating as a general entertainmentindependent station, the station offered a lineup of cartoons, sitcoms, drama series and movies during its early years. The station also aired Asian programming, primarily on weekends. In its early days, it carried business news programming from the Financial News Network, ethnic programming from the International Television Network, and carried ABC, CBS, and NBC programs that KITV, KGMB and KHON-TV chose to decline; programming from ABC's daytime lineup that was preempted by KITV was the most visible on KSHO's schedule. At the same time that channel 26 launched, the station would get more competition when KIKU, which had a part-English/part-Japanese programming schedule up until 1980 when it reverted to an English-language general entertainment format but retained some Asian language programs airing during the day, began adding more English-language programming and moved most of its Japanese programming to Sundays in an effort to be more competitive with KSHO. That would later be followed by the debuts of four additional stations that also added English-language first-run programming at the time: KHAI-TV in 1983, KWHE and KBFD in 1986, and KFVE in 1987. In between that period, channel 26 changed its call letters to KMGT in 1986. From 1986 to 1990, the station was branded as "K-Magic"—and even carried Los Angeles Lakers basketball games featuring Magic Johnson. By 1989, KHNL and KFVE had taken the first- and second-tier syndicated movies and reruns meant for broadcast by independent stations, and KMGT was running a schedule of lower-budget programs. Knowing the station was a money-losing proposition, Mount Wilson FM Broadcasters sold KMGT to Oceania Broadcasting Network for $4.3 million. By 1990, KMGT began phasing out general entertainment programming in favor of carrying Home Shopping Network and religious programming from TBN as a dual affiliate; the station eventually changed its call letters to KOBN in 1992. The following year, the station was sold to All American Broadcasting. In 1996, the station would switch call letters again to KAAH; it dropped HSN programming that year and began carrying TBN programming full-time. The Trinity Broadcasting Network would later buy the station outright in 2003; however, although it is owned by a nonprofit broadcaster that operates mainly non-commercial stations, KAAH-TV continues to be licensed by the Federal Communications Commission as a commercial outlet, KWHE-TV and KUPU. KAAH operated KLEI in Kailua-Kona as a satellite station during the 1990s; that station is now a full-power standalone outlet serving as an affiliate of Telemundo. KAAH formerly operated a low-power repeater station, K34HC in Hilo. TBN took K34HC off-the-air on April 13, 2010 due to declining financial support, which has been attributed to the digital transition.
Digital television
Analog-to-digital conversion
In February 2006, K34HC was granted a construction permit to begin converting operations to digital television prior to being taken off the air. Had it been completed, the station would have broadcast at an effective radiated power of 15 kW. KAAH-TV discontinued regular programming on its analog signal, over UHF channel 26, on January 15, 2009, the date in which full-power television stations in Hawaiitransitioned from analog to digital broadcasts. The station's digital signal remained on its pre-transition UHF channel 27, using PSIP to display the station's virtual channel as its former UHF analog channel 26.
