That was his point, next time you log on to send messages to the list or
whoever or whatever take a radio, and see how much RF you will hear.  Yopu
hear a lot, and it comes from lap tops and PCs a like.  I'm in Detroit,
and in my house once in high school I was using a lap top and couldn't
hear WJR AM which we all should know is in Detroit, and should be pounding
in.  Now, I'm sure that this same lap top that I had at home was used on
plains many times, and back a long time ago for navagation plains used
radio to navigate, and listened for stationsl ike WJR to tell them where
they were going.
