The station's frequency is 98.9 MHz, and broadcasts at an effective radiated power of 39,000 watts, from a transmitter located near Orion, Illinois.

WHBF-TV joined the fold in July 1950, with all three facilities housed in the Telco Building in downtown Rock Island.

Clear Channel Communications (now iHeartMedia) operated "All Hit 98.9" under a joint sales agreement (JSA) with the station's owner, Mercury Broadcasting Company, for several years.

Clear Channel already owned six stations in the Quad Cities market: WLLR-FM, KUUL-FM, KMXG-FM, KCQQ-FM, WOC, and WFXN.

Because purchasing additional stations would have placed Clear Channel over Federal Communications Commission ownership limits for the market, a JSA was used instead.

Under the new rules, a joint sales agreement is considered equivalent to station ownership, placing Clear Channel over the market limit.

The last song ever to be played on "All Hit 98.9" was "American Pie" by Don McLean, which was followed by a tribute medley produced by "Red Hot" Brian Scott.

The final section of a song to ever be played on "All Hit 98.9" was "It's So Hard to Say Goodbye to Yesterday" by Boyz II Men.
