Yup, and the ENG crew went out and searched for hours looking for the only three people in Chicago that were offended by it. LOL
With the increasing tendency for stations to link to their transmitters over IP, due largely to the scarcity of microwave spectrum in most markets (large and small believe it or not) they have left the door open for intrusion. At least in the old days you had to build gear, now you can sit at home with some clever software (and probably some inside knowledge about the target station) and cause chaos.
