92.5 FM WJSZ ASHLEY, MI

WJSZ is an FM radio station operating on 92.5 MHz from Ashley, Michigan, United States, with 4,000 watts. The station features a hot adult contemporary format targeting the Owosso, Michigan area.

The call letters were assigned on December 13, 1991 and the station came on the air shortly thereafter with an "Oldies and More" format playing songs from the 1950s, 1960s, and 1970s.

In 1999 Owosso Broadcasting, the original owners, sold the station to Curwood Broadcasting which repositioned it as Z92.5 "The Castle." The Castle refers to Curwood Castle, the former home of the writer James Curwood located in Owosso, Michigan. The station began referred to itself as "All Request Radio" and "Z92.5 The Castle, Playing the Hits You Want to Hear." Eventually the station dropped the "All Request" angle and evolved into a very broad-based Modern Rock/Classic Hits hybrid.
