Eric -
Thanks for the explanation. Your succinct paragraph said it all
compared to the 32 pages of rants on the eham.net site. Actually, it
wasn't all ranting but, rather, some interesting history on the
development of repeater pairs and the various successes and non-
successes along the way. Our eastern/central NY coordinators are
coming to make a presentation at the Rochester HamFest on June 3. It
should be interesting.
