Does anyone have any knowledge of Jackie's radios?
Given that the producers of
Smokey and the Bandit realized - after the release - that Mr. Gleason wasn't pushing the "push to talk" button on the microphone he held while acting in the film, I'd say that "anyone" had more knowledge of radios than he.
They hired a PR firm, which spread stories about how he and his co-stars had each been using a "Foot Switch" to key their respective CB sets, and went so far as to have some manufactured and sold at truck stops and other CB outlets.
