Early history

96.5 FM signed on in December 1988 as WLWJ owned by Larry Langford, Jr. Langford owned stations in Chicago and South Bend such as WVON and WLLJ/910 (now WGTO). WLWJ was mixed of a Rhythm leaning oldies rock station.

96.5 UBU

In February 1991, the calls were changed to WUBU, as "96.5 UBU" with an urban adult contemporary format. WUBU, owned by Larry Langford, Jr. (who owned a similarly formatted station in Cassopolis, WLLJ-AM 910, now classic hits WGTO and still owned by Langford) was Kalamazoo's first FM R&B station and was highly supported. There was support to maintain this only R&B station in the area, mostly from students on WMU's campus.

In June 1992, the station was bought out by Tri-State Broadcasting, Inc., after WUBU was unable to generate enough revenue to support itself. The WUBU calls were dropped as well as the urban AC format. (The WUBU call letters and format were eventually picked up by 106.3 FM in South Bend, Indiana.) Throughout the years, there have been attempts for another FM R&B station. Today, Midwest Communications operates WTOU (1660 AM) with a similar format to that of WUBU.

96.5 The Fat One/WFAT (AC and Classic Rock)

On June 9, 1992, the station acquired the calls WFAT and switched its format to oldies, then all-1970s hits, then classic hits, and finally to Hot AC as 96.5 The Fat One. In the late-1990s, the station flirted with a CHR/Pop format briefly in competition with WKFR. By April 2000, the station switched its format to mainstream AC with Rick Dees coming to the station for mornings, Robb Rose as Program Director/Middays, Chris in the afternoon, and Delilah at night.

The mainstream AC format did not last long against WQLR and WOOD-FM, and on October 7, 2001, it became a classic rock station with the syndicated Bob and Tom Show in the morning drive. Midwest Communications purchased WFAT, as well as WNWN-AM and WNWN-FM From Tri-State Broadcasting.

Y96.5/WKZO

On February 15, 2008, at 5 p.m., the station abruptly flipped to country music. The last song on WFAT was "Happy Trails" by Van Halen, after which the station became "Y96.5", with the first song of the new format being "It's Five O'Clock Somewhere" by Alan Jackson and Jimmy Buffett. A couple of days later, the station changed its callsign to WYZO.

On March 31, 2010, the station underwent changes again, dropping the country format in favor of a simulcast of its sister station WKZO (590 AM) which airs a news/talk format. The call sign was also changed to WKZO-FM to mirror its AM counterpart on April 5, 2010.
