Local media blogger Rich Lieberman reports that the openly gay radio host Karel, who lost his job at KGO after shouting obscenities on the air during a news report about “Joe the Plumber,” is returning to the local airwaves. Karel, whose real name is Charles Karel Bouley, has been hired by Clear Channel’s John Scott to do afternoon drive on KKGN “Green 960,” an A.M. station that has a liberal point of view.
