Claim: WFNN is licensed to a station in Escanaba, Michigan and it later became a Fun 104 station that was separate from its sister station.
Evidence: Most programming was separate from its sister station, WDBC, with a few exceptions including simulcasts of Casey Kasem's American Top 40. In the late 1970s and early 1980s, WFNN was "Fun 104," an automated Top 40 station.
