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 Codin Broadcasting, LLC.^[2] WNSX's music format is a mix which includes primarily soft and mid-tempo classic rock artists such as The Eagles, Genesis, Boston, The Beatles, Fleetwood Mac, Billy Joel and Elton John, but avoids more harder-edged artists like AC/DC, Def Leppard, Guns N' Roses, and Jimi Hendrix. 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.
