Mark Forgive me, but your post (below) thoroughly confuses me. The end of the first paragraph refers to "Part 2". --Part 2 of what?- The (assumed to be a quote) in a different font seems to be ambiguous in regard to mode, since it appears to be applicable to both wired and radiated modes. Please help, particularly with regard to the definitions of "telegraphy" and "Telecommunication". The (assumed) quote does not appear to be an official document, because of certain internal references to specific programs. Thanks-Bill-W4BSG
