WMMK started out in
the early 80's as a class A country station nicknamed "K-92". For much
of that decade, "K-92" was the market's #1 ranked Arbitron station. Other
country competition changed that in the 90's until the station finally
changed to oldies. WMMK has since upgraded from class A to C3, though proximity
to a local airfield keeps the tower under maximum C3 height. Gets considerable
interference from co-channel WZEW.
