In September 1979, WDPC was denied by the FCC to start operations under the call sign WKRP, however, approval was eventually granted and the company did not change its call sign to WDPC until 1989.
WDPC signed on in September 1979 as WKRP. At first, the FCC denied the call sign to the new station, stating that MTM Enterprises, the producers of the popular CBS television series WKRP in Cincinnati, had a 'hold' on the call letters. When the station's lawyer pointed out to the FCC that "MTM is neither a licensee, nor a permittee. Therefore, MTM has no legal basis to reserve the WKRP callsign", the FCC allowed the assignment. In August 1989, the station switched to WDPC, meaning Dallas/Paulding County.
