WDAQ first signed on in 1948 as WLAD-FM, one of the first Class A FM stations to sign on in the United States and the first to sign on in the Danbury area (over a decade prior to the sign on of the higher powered WINE-FM). Originally, the station was part of the Rural Radio Network as one of two Connecticut affiliates of the New York-based network. This programming would last until the 1950s when WLAD-FM evolved into an extension of its then daytime-only sister station, WLAD-AM.

In the mid 1960s, spurred on by FCC regulations forcing FM stations to create formats separate from their AM sister stations, WLAD-FM upgraded to a stereo signal and flipped to an automated easy listening format. In 1979, the call letters were changed to WDAQ, competing with WEZN from Bridgeport and WHUD from Peekskill, NY for Greater Danbury's easy listening audience. The station gradually shifted to soft adult contemporary. In 1986, the station rebranded itself as "Lite 98" and shed the easy listening instrumentals.

By the late 1980s, WDAQ faced a more crowded market of adult contemporary signals. WEBE Westport/Bridgeport adopted the A/C format in 1984 and then WEZN contemporized its easy listening format in 1987. Seeing an opportunity between teen formatted WKCI-FM, mainstream A/C WEBE and soft A/C WEZN, WDAQ was reborn as Hot A/C 98Q in September, 1989. The station's initial music mix relied heavily on 1970's titles that had not been played on the radio for several years. Within a year, WDAQ shot to #1 beating sister full-service WLAD and crosstown rocker WRKI.

During its more than 20 years as "98Q," the station has finished first in the majority of Danbury Arbitron market ratings surveys. The station continues to be hyper-focused on Greater Danbury as opposed to the more regional approaches of the other FM stations in the market.
