The station first went on the air as WRDS in 1995. The station used the
syndicated urban adult contemporary service known as "
The Touch" with the syndicated
Tom Joyner Morning Show heard in the morning. On December 20, 2000, the station changed its
call sign to WZUN. It aired a
soft adult contemporary format, calling itself "Sunny 102". On September 12, 2009, WZUN switched from soft AC to classic hits. Effective October 1, 2013, Galaxy Communications sold the station to Wayne Mack's WZUN Communications LLC for $1 million. The move was made primarily to address ownership caps in the market.
Oswego and Syracuse are considered to be in the same market in terms of
FCC regulations. Galaxy owns two other stations in Syracuse, 100.9
WKRL-FM "K-Rock" and 99.5
WTKW "TK99," as well as two in the Oswego area. This meant Galaxy would have five FM stations in
Central New York, one more than allowed. The ownership of these stations was allowed under a
grandfather clause, but a restructuring of Galaxy Communications's corporate structure resulted in the station cluster losing its grandfathered status. In March 2016, Galaxy combined WZUN-FM's DJs with the on-air staff of
WSEN-FM 92.1. The newly merged station at 102.1 was initially expected to carry the "WSEN-FM" call sign. This turned out not to be the case, as
Craig Fox, who was purchasing FM 92.1, parked the WSEN call letters on his own
rival station on 103.9 FM. WZUN once again came under the ownership of Galaxy Communications, after it got its grandfather clause status reinstated. Galaxy bought the 102.1 license back from Mack on February 29. The move was made as WSEN-FM's previous frequency, 92.1, was traded away to Craig Fox in a three-way station trade that involved Fox, and the religious
Family Life Network. These dealings resulted in Syracuse being a rare
radio market with competing classic hits stations. The station began sharing its call sign with its sister station on
AM 1070 (formerly WSCP) in June 2018, with 102.1 becoming WZUN-FM and 1070 becoming WZUN. AM 1070 is now part of a simulcast with WZUN-FM. ==References==
