History
In 1971, the station signed on as WSUB-FM. It was the FM counterpart to WSUB (980 AM, now WXLM). Both stations were owned by the Southeastern Connecticut Broadcasting Company. The "SUB" in the stations' call signs stood for "submarine", because shipbuilding is a major industry in the area.

At first, WSUB-FM simulcast the Middle of the Road (MOR) programming heard on the AM station. After a few years, it began playing Top 40 music separate from WSUB 980 AM. The station started with the TM studios syndicated stereo rock format. To give it a different identity, the call sign was changed to WQGN-FM on August 6, 1979. The station became known as Q 105.

In the early 2000s, WQGN and WSUB were owned by Citadel Broadcasting. Citadel merged with Cumulus Media on September 16, 2011.
