KSIV-FM  KSIV-FM is a Bott Radio Network radio station serving St. Louis, Missouri. The station has been a Bott outlet since 1996, though the license history stretches back to the establishment of KSLH, an educational station that was owned by St. Louis Public Schools, in 1950. The St. Louis city board of education applied to the FCC to operate a new noncommercial FM radio station on September 25, 1944, which was granted by the Federal Communications Commission on June 11, 1947. The station took nearly three years to be built; in May 1949, the board approved $60,874 in bids for the construction of the facility at the district's audiovisual building at 1517 S. Theresa Ave. By year's end, construction was nearly complete on the facility, including a tower, as well as a total of five studios and two control rooms. KSLH finally began broadcasts on April 13, 1950, with receivers set up in 191 city elementary schools. Despite coming on late in the school year, KSLH quickly settled into a schedule. All but three of the station's initial 15-minute programs were for grade school students; the exceptions were high school fare on poetry, choral music, and business. KSLH devoted itself almost entirely to instruction for most of its life. By 1953, it broadcast from 9:10 a.m. to 4:15 p.m., matching the school day; it produced about 300 educational programs in a given year, alongside content obtained in the National Association of Educational Broadcasters program exchange. Eight different planning committees worked with teachers on the development of radio courses, while many programs aired at different times to suit the needs of the city schools. In its first decade of broadcasting, the station produced 2,878 fifteen-minute programs. In addition to NAEB-supplied programs, KSLH educational broadcasts were also supplied by the state of Missouri, the United Nations, and even the Canadian Broadcasting Corporation and BBC. Among its staff was at least one alumnus who went on to a lengthy career in St. Louis broadcasting: future KMOV-TV anchor Julius Hunter, who at one time taught in the school system, worked at the station as a writer-producer in the late 1960s. The station, however, still broadcast during the day, and it was silent entirely on weekends and when school was not in session; aside from an afternoon hour of adult shows, it did not expand into evenings, saying the cost of doing so was prohibitive.
