Um... don't you mean "charge" instead of "current"?

As a HAM radio operator, this is why I want to build a transceiver that has no semiconductors in it. If it's not connected to a large antenna, or to the AC network, or to any long wires, there's no way anything coming in from space could fry it (that would not fry me too).

"Current" is moving charged particles (usually electrons). In the moment that they're being shed, the electrons charging the satellite become a current.

No. Current is a rate of charge per time. It's like saying you're dumping a bucket of flow rather than a bucket of water.
Which... is what I said?
exactly
If you arent attaching it to anything, put it in a tinfoil sac. It will be fine and ready to go when needed, semiconductors and all.
Well, if you go into the physics of the whole thing, penetration depth, skin effect, absorbance, etc, you realize there's always a combination of factors that will screw up your silicon. Plus, if it's not in the bag when it hits, it gets fried. Plus, it should be more like a military-style box than a bag.

Tubes are just a heck of a lot harder to screw up, except mechanically.

Not if the storm lasts. Then his setup might be more useful.
I'm curious what you use in place of semiconductors? Vacuum tubes?
yup
