WFMN (originally W31NY) was a commercial FM radio station located in Alpine, New Jersey. It was licensed from 1941 until around 1953 to inventor Edwin Howard Armstrong, and was co-located with two other Armstrong stations, W2XMN (until its suspension in 1949), and W2XEA/KE2XCC (1945-1954). However, for most of its existence WFMN was authorized for significantly lower power than the other two stations, and appears to have rarely been on the air.
