Between 1979 and March, 1986, KUHF's format was NPR news and jazz. In March 1986 local commercial classical music station KLEF changed its format and donated its 12,000+ disc library of music to KUHF, with the proviso that the University of Houston commit KUHF to a format that served Houston's classical music audience, recently disfranchised by the loss of KLEF. The broadcasting of classical music was explained by citing that the charter of KUHF was to provide music unavailable, otherwise, to Houston. KUHF began airing classical music during the day and late night jazz from 10pm to 5am, with NPR news in the morning and afternoon drive time hours. During the summer, former KLEF Operations Manager John Proffitt was hired as the new General Manager for KUHF, and he arrived at his new position on August 3. After the next on-air fundraiser in October, which was aimed at NPR, classical and jazz listeners, KUHF eliminated its remaining jazz broadcasting. KUHF GM Proffitt defended eliminating several genres of jazz from Houston radio on the basis that the number of daytime classical listeners far exceeded the overnight number of jazz listeners.
