Shortwave radio? One of my kids home school friends built a Ham radio, I don’t know a blasted thing about them. Range, Channels, needed power supply, ect..? Oh ya, to steel the early propaganda from the left- Think local, that’s where our power is. Local groups can unite with other regional, then national groups
I suggest a little education!

Complete information on obtaining your license. It isnot hard as they have removed the Morse Code requirement. As smart as you all are could probably pass the multiple guess theory inside of a month.
I volunteer my time at the EOC of the County performing communications tasks and building a real Ham station in a hardened bunker. We now have a 100’ tower atop a big hill populated with antennas for all bands from DC to light.
I also have an old tube type transmitter/receiver in case of EMP. I believe we are not far from anarchy in the streets. We saw what happened in Iran when things went bad. They shut down access. Or tried to :)
