The station is owned by Townsquare Media and broadcasts a classic rock radio format, simulcasting WQBK-FM (105.7).

WQSH has an effective radiated power (ERP) of 50,000 watts, the maximum for this section of the Northeastern United States.

The next year, WACS-FM was sold to the owners of WSHZ (98.3 FM) and began simulcasting that station's adult contemporary format, and later its oldies music, using the call letters WSHQ.

Radio Enterprises was bought out by Clear Channel Communications, which had owned a minority share of the company, in 1997.
