Established in 1957 as WSME, the station is licensed to serve Sanford, Maine, United States.

The station was acquired by Port Broadcasting, which also owned WNBP in Newburyport, Massachusetts, in 2012.

[5] WWSF's "Legends" format was identical to that of WNBP, though the two stations were programmed separately.

[6] In February 2019 Port Broadcasting sold W272CG to Maine Public, which used the translator to rebroadcast its statewide classical music format.

The rebranding followed the sale of WXEX and WXEX-FM to the Educational Media Foundation to become K-Love stations WPKC and WPKC-FM.
