Radio is a scorpio?

On this day in 1920, KDKA (1020-AM) in Pittsburgh became the first commercially licensed radio station continuously operating. Others claim WHA in Madison, WI or XWA (later CFCF and now CINW) in Montreal, Canada, were first, but KDKA had the best publicity department, and may have gotten the first certificate from the Department of Commerce (before there was a Federal Commuications Commission).
