“Jazzy 93.7” went on the air on November 5, 1995. Dr. John Carollo was the original licensee, having survived a seven-year battle to win the license after twenty others applied for it. After spending a reported $200,000 to nail down the license, Carollo quickly turned to Sonoma County’s dominant broadcaster to actually run the “smooth jazz”-formatted station.
KJZY became the latest station in the portfolio of Gordon Zlot‘s Redwood Empire Stereocasters. Initially, Zlot ran the station under a local marketing agreement (LMA), but in June 1996, his company paid $725,000 to acquire the station outright. While the station is licensed to Sebastopol, its studios have always been located in Santa Rosa.
Between 2020 and 2022, the station’s call letters were switched to KBBL while it broadcast a country music format and branded itself as “93.7 The Bull”. During that period, the KJZY call letters and programming were heard on Cazadero’s 106.3 FM frequency.
A change back to a music mix of adult standards brought a return of the KJZY call letters in July 2022.
