@roadriverrail @flockofnazguls @th So what happened was, back in those analog days, WGN and WTTW transmitted a link to their main transmitters on top of the Hancock Building and Sears Tower (I forget which was which). The hijacker basically sent a stronger signal than the station link, and because of FM capture, voilĂ - the hijackers signal wins.
@roadriverrail @flockofnazguls @th the problem with a van in downtown Chicago is all the buildings block line of sight.
