Being a prepper and a Ham I found the article “EMP-Hardened Ham Radio Communications” by PrepperDoc very interesting but also somewhat over my head with regard to tubes and the like, so I put it out to more experienced members of our ARC (amateur radio club) for comment. The response from one Ham is not a slam but rather additional information for the like-minded. “There was no mention of electrolytic caps and the frequent need to replace them when using older gear. Also, tube rigs are power hogs; where are you going to get the power? Alternate power sources (inverter generators, solar panels, charge controllers) all have solid state elements and are likely to be damaged. A better solution might be to keep some low power gear in a Faraday cage along with a small solar charger and battery.” Regards, – E.G.
