WHMH-FM officially signed on the air in October 1975. The station was established by Herb Hoppe as the FM sister to his heritage AM station, WVAL. Initially, the station carried an adult contemporary format, serving as a softer alternative to the high-energy country programming on its AM counterpart. The station's branding and identity are deeply tied to its physical location, known as "The Red House" on 2nd Street North in Sauk Rapids. Following Herb Hoppe's passing in 2018, the station has remained under the family's ownership through Tri-County Broadcasting, currently led by Gary Hoppe. For decades, WHMH operated from a tower co-located with KLZZ on the south side of St. Cloud. However, in 2015, the station completed a significant technical move, relocating its primary transmitter back to the Sauk Rapids studio site. While this move involved a slight decrease in power to 40,000 watts, the new antenna location allowed for improved signal penetration into the northern and eastern portions of the St. Cloud market. The station's long-running "Rockin' 101" identity was forged in the 1980s as the station shifted toward a harder-edged active rock format. It is a primary competitor to Twin Cities-based active rock stations like
KXXR (93X), often distinguishing itself through heavy local promotion and its status as a fully independent, family-owned outlet. In early 2021, the station hired Twin Cities radio veteran John Lassman to host "The Johnny Rock Show" and serve as operations manager, a move aimed at refreshing the station's heritage rock image. ==Controversy==
