Its transmitter is atop Mount Washington, the tallest peak in the Northeast, alongside sister station WHOM (94.9 FM).

[3] It primarily serves northern New Hampshire and western Maine, but its city-grade signal can also be heard in parts of Vermont and Quebec.

The 103.7 frequency now occupied by WPKQ began in March 1952 as WMOU-FM, the FM sister station to WMOU (1230 AM) in Berlin.

In 1996, 103.7 adopted its present callsign and a country music format, simulcast from WOKQ in Dover, upon its sale to Fuller-Jeffrey Broadcasting.
