Danny Clayton was hired as the first (and only) program director for WFZH, having previously spent his Milwaukee radio career at adult contemporary-formatted WKTI. Other original staff members included Milwaukee radio veteran Andi Miller. Personalities who later joined "The Fish" included Jon Hemmer and Rick Hall.
For a time, WFZH had a friendly rivalry with co-owned WZFS in Chicago, which included a paintball game between the stations' employees. This rivalry lasted until the Chicago station was sold to Univision Communications in 2005 and WZFS became Spanish language AC station WPPN.
In February 2008, Salem sold WFZH and WRRD in separate deals.[3] WRRD was purchased by Good Karma Broadcasting, which moved the all-sports format of WAUK (1510 AM) to 540 as WAUK. WFZH was sold to the Educational Media Foundation; it remained a contemporary Christian music station, but switched from local programming to EMF's K-Love national network. This took effect after midnight on February 15, 2008, following two days of on-air farewells from the "Fish" staff. On May 30, the call letters changed to WKMZ. On April 29, 2011, WKMZ changed its call sign to WLVE to go with the "K-Love" branding.
