Kim: The acid rain thing back East was a Master's Thesis that no one read until one day some semi-scientist found it. He read it and gave the information to the, then fledgling, environmental groups and look what we have today.
Some day someone will read one of your papers and find a new way to power cars, take pictures or communicate. Too bad you can't patent your stuff for ever. The people who developed spread spectrum waited until after the patent expired to develop it and the poor actress who conceptualized and patented it got nothing. 73 Jim de W5JO ----- Original Message ----- From: "Kim Elmore" <[EMAIL PROTECTED]> To: "Discussion of AM Radio" <amradio@mailman.qth.net> Sent: Friday, July 09, 2004 3:34 PM Subject: RE: [AMRadio] WW II Army Field Sets > Wow!
