KKSY-FM

The station signed on the air on February 27, 1963 (February 27, 1963). The original call sign was WMT-FM, the sister station to WMT 600 AM, the oldest station in Cedar Rapids. At first the two stations simulcast. But by the late 1960s, WMT-FM had its own format: easy listening, jazz and classical music. There were 90-minute classical music segments in the morning and evening with regular programs of jazz and show tunes from Broadway musicals. Some of those early announcers were Keith Webster, Bill Dutcher, Don John Ross, Bill Grubbe, and Jim Wicks as well as other WMT 600 announcers who took the helm of hosting on FM. WMT-FM would simulcast the 15-minute newscasts of WMT AM 600 several times a day.

In the 1970s, WMT-FM became a full-time beautiful music station. It played quarter hour sweeps of soft instrumentals, with some Hollywood and Broadway show tunes.

In an effort to sound younger, WMT-FM added more soft vocals to its easy listening sound. But by the 1980s, the audience for beautiful music was aging. WMT-FM switched to an adult contemporary format in 1982. It was the dominant AC station for the Cedar Rapids market. The amount of adult contemporary stations in the Cedar Rapids market (excluding Waterloo) was upgraded from one to three when WMT-FM's sister station WMT-AM flipped from MOR to adult contemporary in 1986, and KCRG returned to its adult contemporary format after a nearly three-year hiatus in January 1987. Both WMT-AM and KCRG-AM's adult contemporary formats didn't last long. WMT-FM became the only (and dominant) AC station in the Cedar Rapids market after WMT-AM flipped back to MOR in late 1988 and KCRG-AM flipped to oldies in 1989.

WMT-FM's studios have been located at Broadcast Park on Collins Road in Cedar Rapids, along with its AM sister station WMT and TV station KGAN (the former WMT-TV), since it signed on. Until the 1970s, the studios of WMT radio were located on the fifth floor of the historic Paramount Theatre building in downtown Cedar Rapids.[3] It was one of the few stations with a callsign beginning with W located west of the Mississippi River.

By the early 2000s, WMT-FM stepped up the tempo of its playlist and transitioned to Hot AC. The station was known for its "time warp weekends" and long-standing tradition of being heavily involved in the Cedar Rapids community. The station hosted "Uptown Friday Nights" every Friday night in downtown Cedar Rapids. WMT-FM often joined up with WMT for special promotional events, and simulcasts during severe weather conditions.

WMT-FM ended its longtime hot adult contemporary format on December 27, 2011. Its owner, Clear Channel Communications, transferred the country format from co-owned KKSY 95.7 FM, to 96.5 MHz. The call letters on 96.5 were switched to KKSY-FM. For several weeks, there was a temporary simulcast period.[4][5] 95.7 FM began to simulcast WMT on January 2, 2012 and eventually took the KWMG call letters on January 17, 2012.[6]

In 2014, Clear Channel changed its name to iHeartMedia, Inc. As an iHeart Country station, KKSY carries The Bobby Bones Show Monday through Saturday mornings from Nashville. And in overnights, KKSY carries After Midnite with Granger Smith, both shows syndicated from co-owned Premiere Networks.
