Sorry there, didn't mean to hijack your thread. :-\ The mention of Commodore and Commodore Amiga, and using shortwave to transmit data got me off on a tangent, a combination of nostalgia for a simpler, stone-tools past, and a vision of future possibilities, how to use stone tools in new and interesting ways. That was my reason for interest in using some small part of the radio spectrum for internet: maybe limited in speed, only able to transmit plaintext, email or text messages, but also its range is much greater than wifi. AM radio signals at night, for example, in remote places, without much interference, can be picked up many hundreds of miles farther away than usual in daytime. Even FM transmission can travel over pretty far distances, in the right conditons. Aside from ham radio and shortwave, I wondered what else might be possible. E.Liddell's recommendation of ham radio seems the most viable way to purse, at present. It's also a fun hobby all on its own, aside from the potential of using it for internet. We might someday find ourselves in a situation where this could come in very handy.
