Amateur radio. My radio shack is all set and ready fire on many hundreds of watts. By today's standards, a 'primitive' form of communication to be sure. But in a pinch, it's not easy to cut off. And under the right conditions, I am able to reach Alaska and overseas.
I have friends and relatives that are Hams’ and they spend a lot of free time on the air.
Barry Goldwater was a Ham. Call Sign (in case you forgot was K7UGA)
