Yup, difficult to test.
If I were worried about this sort of thing, I'd dig a fallout shelter and put a couple uBitx's in there all wrapped up in tinfoil.
Unlike NORAD, I don't have to remain on the air during the event.
What about something like a Carrington Event?? ?
Would protective measures against that be similar?
We get a lot of lightning storms here.
I try to unplug the gear, but then that may not always happen soon enough.
Would be tough for the rig to survive a direct strike to the antenna.
But when a storm's anywhere in the area there are significant electrostatic fields
that should be possible to deal with.
I assume the GDT and some diode scheme would be part of any modern attempt.
A big knife switch nailed to the wall would look kind of cool.
If we must have extra diodes and if they are found to create hash, then perhaps have them at the
antenna port of some external antenna tuner.
Alternately, put diodes in front of some bandpass filter such as this, again outside the uBitx:
