History
98.3 FM history
The 98.3 frequency was home for many years to WZMF, which signed on the air in July, 1966. At its inception, the station aired a MOR format. WZMF was located in a small house on Shady Lane in Menomonee Falls.
WZMF's pop music programming eventually became more experimental, and the station evolved into a freeform progressive rock format by October 1968, one of the first stations to do so in the midwest. The station was moderately successful with the format for the next eleven years, pushing rival WTOS into a different format and staying competitive with leading rocker WQFM. When WISN-FM switched from beautiful music to rock as WLPX in January 1978, immediately becoming a ratings success, WZMF began to tighten their format, amid protests from the station's on-air staff, and ratings dropped.
