CMEs won’t damage a ham radio if it’s unplugged and isolated from any long wave antenna.
*IF* a really big CME was forecast to hit the earth, we’d have plenty of time to ‘unplug’ a number of vulnerable assets. That could include shutting down the electric grid and waiting it out.
How long do you want to go with the grid down, and no communications? And essentially no legal commerce? No emergency services. And post-EMP, dead vehicles everywhere.
