... I have an interesting story about frequency hopping.It was actually invented in 1940 by my father and the movie actress Hedy Lamarr. They wanted to design a secure radio controlled torpedo.My father and Hedy,being familiar with player pianos (my father was a composer) had the bright idea of using two identical player-piano rolls to synchronize the frequencies of an independent transmitter and receiver... Unfortunately this idea was a bit ahead of it's time and the patent expired before they ever received any money for it. C' est la vie.. -Chris Beaumont ccat@netcom.com -- __ "I guess that's what happens when you let Puritans found their own country."
