In 1956, Western Illinois University establishedWWKS for educational radio broadcasting at 91.3 MHz with 3,000 watts. The station's FCC call letters were attributed to William Kimbrough Shake, who installed the equipment acquired fromGates Radio, in Quincy, IL. The station's mission was to provide educational programming primarily for the growing K-12 audiences in west-central Illinois. The radio studios were located in Tillman Hall (the "new science building") and a 250-foot (76 m) radio tower was constructed south of Murray Street, at the north edge of the university in 1956.
With the completion of the university's "new library", Memorial Hall in 1962, WWKS studios were relocated to the top floor. The radio station and adjacent video studios would remain at this location for the next 40 years. The station's sole full-time employee throughout the decade is Elmer "Tug" Haddock, who served as General Manager and provided supervision of volunteer student announcers. In 1964 Sallee Hall (College of Fine Arts and foreign languages) was built along Murray Strret and adjacent (north) of the WIUM tower, the station's transmitter was moved to the roof of Sallee Hall in a specially designed enclosure. The station's FCC call sign was changed in 1970 to WIUM, to better reflect the station's ownership (Western Illinois University - Macomb) and mission.
1978 - WIUM increases power to 7,200 watts. The 19-hour broadcast day features classical, jazz and rock music with some local news, sports and weather. The Radio Information Service is created to broadcast readings from local newspapers through specially tuned receivers placed with people with aprint disability. The service was inspired and initiated by Helen L. Wear, the first blind woman to graduate from Western Illinois University.
1981 - WIUM relocates its transmitter to the new 500-foot (150 m) tower at Western Illinois University's Horn Campus south of Macomb. This tower was constructed to jointly support WIUM-FM and the newPublic Broadcasting Service (PBS)television station (WIUM-TV),CONVOCOM to serve west-central Illinois. The original WIUM-FM tower adjacent to Sallee Hall was dismantled in the following years.
1982 - WIUM qualifies for Corporation for Public Broadcasting support and becomes a member station ofNational Public Radio. Coinciding with the addition of NPR programming is the organization of a second station to be run and programmed by WIU students (WIUS-FM, now in the Department of Broadcasting in Sallee Hall).
