KTUH was Hawaii's first non-commercial FM station. It signed on the air on July 7, 1969.[5] It was originally heard on90.5 FM and was powered at only 10 watts. The station was originally on the air from 6:30 p.m. to 2:30 a.m. Studios were in Room 206 in Hawai'i Hall. It played a mix ofclassical music,jazz andprogressive rock.
In 1971, KTUH was the first station in Hawaii to experiment withquadrophonic stereo broadcasts.[6] In 1972, the station began broadcasting 24/7. In August 1973, KTUH engineers installed an FM translator atop Leahi Hospital inKaimuki. The station was off the air for three months in 1974 and two months in 1977 as it made transmitter adjustments.
KTUH was originally only heard on campus and in surrounding neighborhoods. It increased its power to 100 watts in 1985 and switched to90.3 FM, moving one spot down the dial. In 1996, it began accepting underwriting sponsorships to add money to the station budget. In July and August 2001, the station was off the air for several weeks to increase power to 3,000 watts. It also began live streaming on its website.
On March 19, 2016, it switched to its current frequency at90.1 FM. That was coupled with a power boost to 7,000 watts and an increase inheight above average terrain (HAAT) to 501 meters (1,644 ft)[7] That gives KTUH island-wide coverage onOahu and some reception onMoloka'i.
