WDPC initially signed on in September 1979 as WKRP. At first, the FCC denied the call letters to the new station, stating that MTM Enterprises, the producers of the popular CBS series WKRP in Cincinnati, had a 'hold' on the callsign. When the station's lawyer pointed out to the FCC, "MTM is neither a licensee, nor a permittee. Therefore, MTM has no legal basis to reserve the WKRP callsign", they allowed the assignment. In August 1989, the station switched to its current calls, WDPC, meaning Dallas/Paulding County.
