Shortly after the station was licensed (as WTUR in 1988 and later WCDJ in 1992), the original owners, Truro Wireless, Inc., ran into opposition from the Truro local government, who objected to a radio tower being built within the town limits. Until such a tower was built, the station could not air a regular broadcast schedule. In lieu of a tower, WTUR/WCDJ would occasionally broadcast just long enough, via a small transmitter, at 340 watts, to keep their FCC license intact.
On March 29, 2007, the FCC granted a transfer of the license of the former WCDJ to Dunes 102FM LLC. The new owners got the call letters changed, and now, as WGTX, they have begun broadcast service as "Dunes 102: Cape Cod's Oldies Radio". The format is an upbeat presentation of oldies from the 1960s, 1970s, and early 1980s, with a target demographic of 25-54. The station is programmed from the "Greatest Mojo" syndicated network feed.
The new owners will continue to upgrade the facility along the way and expect to provide full service to the upper and lower Cape from a 180 ft tower on the Town of Truro's Safety Building site on Route 6.
In 2012, the station dropped the "Oldies" moniker from their branding, re-branding themselves as "Cape Cod's 102.3, The Dunes", in light of the format-wide re-branding of 'oldies' stations.
