Licensed to Winter Harbor, Maine, the station's studios and offices are on Maine State Route 3 (High Street) in Ellsworth. It serves Downeast Maine, including Ellsworth, Bar Harbor, Bucksport, and Machias.

WNSX is owned by Stony Creek Broadcasting, LLC.^[2] WNSX's music format is a mix which includes classic rock artists such as The Eagles, Genesis, Boston, The Beatles, Fleetwood Mac, Billy Joel and Elton John, but avoids pop artists such as Michael Jackson, Madonna, and Prince. The station uses the slogan "Smooth Rock 'n' Roll" to indicate it does not play rock songs that are too hard-edged.

WNSX's transmitter is off Tunk Lake Road in Sullivan.^[3] The station's primary signal serves Hancock and Washington Counties.

Maine businessman Scott Hogg was granted a construction permit from the Federal Communications Commission to build a new FM station at 97.7 in the mid-1990s. It used the call sign WAKN before making it to the air.^[4]
