Launch at 1360 AM This station received its original
construction permit for a 500-
watt station broadcasting on 1360
kHz from the
Federal Communications Commission on September 13,
1982. The new station was assigned the call letters
WABT by the FCC. WABT received its
license to cover from the FCC on June 19, 1983. The station aired a
country music format to start with. In June 1985, The Great American Broadcasting Corporation reached an agreement to sell WABT to Excelsior Broadcasting Corporation. The deal was approved by the FCC on July 19, 1985, and the transaction was consummated on January 22, 1986.
Move to 730 AM The station had applied to the FCC in September 1983 to change frequencies from 1360 kHz to 730 kHz and increase power to 1,000 watts. In July 1985, after WJMW moved from 730 kHz to 770 kHz, the FCC issued a construction permit for the changes. The new owners had the FCC change the station's callsign to
WDKT on December 26, 1985. With new ownership, new call letters, a new frequency, and increased power in place, the station changed to an
urban contemporary format branded as "D-73".
Financial problems Facing increasing financial difficulties, in February 1989 the license for this station was involuntarily transferred from Excelsior Broadcasting Corporation to Excelsior Broadcasting Corporation, Debtor-In-Possession. The involuntary transfer was approved by the FCC on March 2, 1989. In April 1989, Vascular Diagnostic Labs bought out the previous shareholders of Excelsior Broadcasting Corporation, the licensee for this station. The transfer of control was approved by the FCC on July 13, 1989. In August 1989, with the financial issues resolved and the previous shareholders bought out, Excelsior Broadcasting Corporation was dissolved and the license was involuntarily transferred to Vascular Diagnostic Labs owner Dr. Merlin Kelsick. The transfer was approved by the FCC on November 29, 1990.
