I have recently gotten re-interested in ham radio. I got my Technician and General licenses back in the mid 1970's but have been pretty much off the air completely since about 1985 although I have kept my license up to date. Needless to say, a lot has changed since I last used my Wilson 2m HT that had crystals instead of a VFO. I just bought a Yaesu 2900R 2m rig this weekend and am getting my feet wet again after a 27 year hiatus. I would like to upgrade from my current General license to the Amateur Extra. I've noticed that the FCC will allow credit for pre-1987 Technician licenses.
One of my questions is...How do I go about proving that I was licensed pre-1987?
My other question is.... is there a good website that will explain things like "Packet" and "Echolink" and other important practices of the hobby to an old dinosaur?
