Ah, my grandfather was a ham (N4MDB) and he always tried to get me interested in it, but I had to tell him I preferred the internet (this was late 80's, so few people actually had internet). Later when I read Stevens networking books I learned there was a whole Hawaii-based packet radio (ALOHAnet) , and the UC campuses had intercampus microwave networking for a while as well. I actually still remember him telling me about bouncing radio waves off the atmosphere which seemed like magic to me at the time.
