On July 26, 1958, the station signed on the air.^[4] For many years the station's call sign was WSUB. Groton and New London are noted for their shipbuilding industry, including the construction of submarines.

The station was originally a daytimer, required to go off the air at night. It was originally owned by Lawrence A. Reilly and James A. Spates. The original studios were at 119 Bridge Street in Groton. It had a full service middle of the road (MOR) format of popular adult music, news and sports.

In 1971, it added an FM station on 105.5 MHz, WSUB-FM (now WQGN-FM). In the 1990s, WSUB got authorization from the Federal Communications Commission to broadcast around the clock, adding low power operation at night.

WSUB and WQGN-FM were owned by Citadel Broadcasting in the early 2000s. Citadel merged with Cumulus Media on September 16, 2011.^[5]
