High school operations

Effective December 1, 1921, the Department of Commerce, which regulated radio at this time, adopted regulations formally establishing standards for stations making broadcasts intended for the general public.^[4] On May 22, 1923, the high school was issued a broadcast station license, with the alphabetically assigned call letters of KFIO.^[5] This was one of the earliest non-commercial educational stations, and one of the few operated by a high school instead of a college.

KFIO was operated by student members of high school's Radio Club. The station broadcast features such as school news, entertainment that included concerts by the school band and orchestra (live from the auditorium) and sports events, in particular games between North Central High and Lewis and Clark High in 1924 and 1925. In addition to Friday evening programs, the station also broadcast during school time Monday to Friday and occasionally on Sunday evenings. Despite some difficulty in and controversy over keeping the station on the air, many of the people who became radio broadcast professionals in Spokane and nearby communities in the early radio days got their start in radio at KFIO.

D. Windsor Hunt, who worked at the station as a student beginning in 1927, related his experiences at the station and talked about what kind of programming the station broadcast. He noted that, among other things, he was responsible for reading the news, playing records, announcing school athletic events, and proms. The station had a library of records, all 78 RPM, mostly from the 1910s, but they also were able to get a hold of more recent hits of the time. Hunt noted that they obtained a copy of the record "Sweet Hearts on Parade" when it was still number one on the hit parade. Hunt also related they would read the news verbatim from the Spokesman-Review and the Spokane Chronicle, but they gave no credit to the original sources. They had to be careful to avoid mentioning divorce, sex, or bootlegging as those topics were considered taboo.^[6]

Hunt's account noted that the station's studio was originally located in crowded quarters on an upper floor in the south end of the high school building. He also stated that: "... The [transmitter] was in a closet about 8' X 16', between the physics lab and classroom, on the south side of the 3rd floor. ... The transmitter took up about six square feet and a two-foot passage alongside led to the studio. This was the back of the room with one window to an airwell. It was about 8' X 12'. ... On the right side was the 'console' - a bench about two feet wide with one turntable mounted on it. Later we got a variable speed job, but we didn't have LP (long play, not liquid petroleum) records so we never used it in my time. ... Someone loaned Mr. A. L. Smith a mechanical song bird from Europe - a wind up dealy in a big brass cage. Every 15 minutes it sang a line in a very beautiful realistic bird song. On the hour it sang a longer trill. It not only warned us of the time but often added a nice touch to the announcements."^[6]

Commercial station

KFIO was financed by the local school board, which eventually reduced its support to a level that no longer permitted the station to remain operating. Thus, on August 23, 1929, the station was sold to the Spokane Broadcasting Corporation and converted to a commercial operation.^[7]

In 1950, with the sale of the station to Louis Wasmer, the call letters were changed to KSPO. This was followed by a series of ownership and call letter changes. Marlin R. Taylor former President of Bonneville Broadcast Consultants owned the station for several years in the mid 1980's. TCC Broadcasting established an "all business" format in 1990, after the station went off the air for a short time. On April 29, 1991, it became KSBN.^{[8] [9]} Owner/Manager Tom Cock sold the station in 1995 to KSBN Radio, Inc.
