WBQQ signed on in November 1991 as a classical music station, branded as "WBACH." The station's programming would subsequently be expanded to several other Maine radio stations (including existing classical music stations WPKM in Scarborough and WAVX in Thomaston); in a 2008 format shuffle, WBACH programming in southern Maine was consolidated at 104.7 FM, and WBQQ was made a simulcast of WTHT. WBQQ was purchased on May 22, 2012 by WBIN Media Company in the same bankruptcy auction as WTHT.
