WKZO (AM)

The station traces its roots back to 8AZ, an experimental station founded by John Fetzer in 1922 while he was a student at Emmanuel Christian College (now Andrews University) in Berrien Springs.

The success of the experimental station, which was heard as far away as France, encouraged the college to look into starting a "real" radio station. The result was KFGZ, 'The Radio Lighthouse,' licensed in April 1923 and broadcasting at 1120 kHz with 500 watts of power. KFGZ's call sign was changed in 1925 to WEMC. KFGZ/WEMC operated as an independent radio station serving the St. Joseph River Valley with community information and Christian radio programming. The station was received across the eastern United States and into Canada, and a reception report once came in from a Dutch ship in the North Sea.

Despite the station's popularity, the fact that it operated non-commercially, with the college unwilling to allow the station to solicit financial donations from listeners, ultimately sealed its fate. By 1930, the college was looking to sell the station. (Andrews University returned to broadcasting in 1971, when the school signed on WAUS, a classical music station at 90.9 (later 90.7) on the FM dial.)

Fetzer purchased the station himself for $2,500. He essentially ran the station as a one-man job, serving as technician, engineer, disc jockey, and sales staff. When the Great Depression struck, Fetzer decided to move WEMC to Kalamazoo, which at the time was the largest city in Michigan that did not yet have its own radio station. The station began operations as WKZO in September 1931, and soon became a success. Famous alumni at WKZO include Paul Harvey, Tom Snyder, and Harry Caray.

In the 1930s, 40s and 50s, WKZO carried the CBS schedule of programs, during the Golden Age of Radio. Listeners heard dramas, comedies, news, sports, soap operas, game shows and big band broadcasts. In the 1950s, as network programming moved from radio to television, WKZO switched to a full-service Middle of the Road (MOR) station, with popular music, news and sports.

In 1950, a television station was added. Channel 3 WKZO-TV began broadcasting on in July.[3] Because WKZO was a CBS Radio affiliate, WKZO-TV was primarily a CBS outlet, although as the only TV station in Kalamazoo, it also carried shows from NBC, ABC and the DuMont Television Network in its early days.

The TV station was sold in 1985 and its call letters switched to WWMT.

In the 1970s, WKZO's playlist shifted to adult contemporary music. Billboard magazine named WKZO the "Adult Contemporary Station of the Year" in 1977, and the station was subsequently honored by the Michigan state legislature with a concurrent resolution of tribute.

Following the station's sale after Fetzer's death, WKZO converted to its present news/talk format in the early 1990s. In 2006, WKZO was acquired by Midwest Communications, based in Wausau, Wisconsin.[4]
