Hugh Wilson did the warm-up during show tapings. During one warm-up, Wilson said he chose the call letters "WKRP" because they weren't being used by an actual station. He wanted to use "WSOS" or "WHLP," but they were taken. During the show's run, a small AM radio station in Georgia applied to the FCC for the call letters WKRP. The show's producers considered legal action, but the FCC said that their trademark rights did not prevent a legitimate radio station from using the call letters, which were granted to the applicant. In March 2014, a non-profit organization was granted the call sign 'WKRP' for a new FM radio station in Raleigh, North Carolina. The station is expected to go on the air in 2015 at 101.9 FM.
