WFMX went on the air March 17, 1990 as a satellite fed oldies format under the call letters WHQO (Standing for "Headquarters for Oldies") changing a few years later to a community-based AC format as "The Light at the end of the dial". In the late 1990s, as ownership of the station changed frequently the station changed formats several times. Including simulcasting the sports of WSKW (1996–1999), top 40 as "The Party 108" (1999–2000), talk both simulcasting WVOM-FM from Bangor and solo before flipping to the current "Mix 107.9" in February 2005. In 1999 an effort was made to donate the station to Maine Public Radio; the donation was never completed, as it was contingent on a never-completed sale of Mountain Wireless' stations to Cumulus Media.
