WZDA (103.9 FM) is a commercial radio station licensed to Beavercreek, Ohio, serving the Dayton metro area, owned by iHeartMedia, Inc. As of December 27, 2021, it broadcasts country music on its standard analog transmission, using the "New Country 103.9" moniker, after previously being an alternative rock station called "Alt 103.9.

[citation needed] WELX and WHBM began operations in the late 1960s with a middle of the road format, then switching in the early 1970s to progressive jazz and soul gospel.

Both stations eventually operated from the WELX transmitter site adjacent to U.S. Route 35 off June Drive in Xenia.

By 1992, the station became WRVF "The River" with a country format before being overshadowed by the former WHIO-FM becoming WHKO "K-99.1 FM",[citation needed].

During this time, WXEG with sister stations WONE (AM) and WTUE (FM) went through several ownerships after being sold by Group One to Stoner Broadcasting, American Radio Systems, Entercom and finally Jacor before its merger with Clear Channel.
