Owned by Woodward Communications, Inc., the station broadcasts an active rock format, and has been a simulcast of WZOR since June 13, 2018.

On March 11, 2009 at Midnight, after stunting for an hour with Spanish contemporary music, the station shifted to Top 40/CHR as "B104"; the first song on "B" was "Circus" by Britney Spears.

[5] Martini Media contested the purchase in court, petitioning that despite a Permission To Deny in their 2008 agreement it was verbally extended past is its 2013 expiration and that Caxambas sold the station before the Federal Communications Commission (FCC) approved the license transfer.

[5] Martini would continue the B104 stream for several months online until entering into a contract with Mountain Dog Media to convert Sheboygan's WCLB (950/107.3), which had recently launched an FM translator, to the same format as "Z107".

[6] On May 1, 2018, Woodward began operating the station and flipped it to a jockless, commercial-free active rock format, as a part of a 1,047-hour stunt (the last song on "B-104" was "Blank Space" by Taylor Swift, which cut off halfway through).
