The station is under ownership of Brent Casagrande through licensee Delmar Communications, Inc, and features a locally programmed classic hits format.

WDLR signed on in 1984 as WUCO with a country music format, switching to oldies in 1991 and adult contemporary in the late 1990s.

Beginning in February 2007, WUCO was also near-simulcast on FM via Lexington-licensed WFOT 89.5 MHz, which services the Mansfield area and is now a repeater of WNOC-based Annunciation Radio.

This enabled St. Gabriel Radio to expand its reach into the Columbus market and its volunteer base (culminating in the purchase of WOSU (AM) from Ohio State University in December 2011, rechristened as WVSG), while also necessitating a divestiture of WUCO.

WUCO was leased over in late 2009 to ICS Holdings Inc., also then the owner of WDLR in Delaware, adopting The True Oldies Channel a satellite-feed service of Citadel Media, and branded itself as "True Oldies 1270 WQTT," despite the WUCO calls still in use and aired at the top of the hour.

It also carries coverage of the annual Little Brown Jug horse racing event in Delaware each September, simulcasting sister station WDLR.
