CIMX-FM
CIMX-FM (88.7 FM) — branded 89X — is a commercial active-leaning alternative rock radio station based in Windsor, Ontario. 89X serves both Essex County, Ontario and Metro Detroit; its 100,000-watt signal reaches most of southwestern Ontario, southeastern Michigan, the Toledo metro area and the western Lake Erie shoreline of Ohio.
CIMX-FM also broadcasts a soft rock music program continuously on its 92 kHz SCMO subcarrier. The program is not intended for public reception, but rather provides background music for businesses, similar to Muzak.
