So when are we getting a amature radio sub? Why do you need encryption? Consider we are communicating on a website that is viewable by anyone with a browser. Some bands like 220 and 6 meters are not used a lot. For example 6 meter simplex with JS8 Call, used on two beams pointed at each other using minimal power. Security through obscurity. That would take a lot of effort for others to listen especially the Feds. Hams are are creative and probably have more ideas. For example I have seen 2 meter 50 watt wifi routers for sale at hamfests. I'm not planning any terrorist attacks, but it would be a nice place to chat with like minded individuals in case the internet becomes completely scrubbed. As far as call signs, just listen to 160 meters, those guys have been speed mumbling their call signs for years. Wouldn't you just want a back up communication device that isn't dependent on government controlled infrastructure?
