OK I understand some of this but if we have a solar storm or an EMP happen, the military is a step ahead of any of us unless we have hardened equipment, right?
I would think (without knowing for sure) that ALL of it is fair game, given a high enough direct-whack from a huge flare, even some of the old hybrid classics like the Kenwood 520 and the Yaesu 101 would be rendered scrap metal. I'm sure the gubment has a pallet or two of mil spec, late model communications gear under under
Cheyanne Mountian or somewhere. Certainly, one or two of my FT-840's would likely be casualties if the whack is big enough, even tho my shop and my radio room both have the makeshift electrical equivalent to faraday cages around them and my diagnostic gear. And still, this whole scenario may be incomplete.
"Prepare for the worse, and pray for the best". I also stored static-sensitive repair components like schottkey diodes, FET's mosfets and CPU's inside ammo boxes in my grounded metal shed, and THEY may not even totally survive.. But talk about post-apocalyptic "currency", those that do are would be worth more than gold in the right hands --- say, that of AF MARS, or the surviving remnant of "The Resistance". Or In such a scenario, would I no longer be a utility inspector, but a bench tech and radio operator for the resistance? Would I be trading my skills and components for bread? And a massive EMP is but one of many possibilities that have the potential to plunge civilization into dark ages or anarchy.
Rouge nations, our own rouge regimes, meteors, super volcanoes -- zombies?

My point is that we cannot ever prepare for
everything, but we can do what we have time and money to, and meet grubby times head-on. I will always do what I can do, and question myself if what I actually accomplished with my prep is adequate, or not... Right now, you're kicking that same question around in your head, i'll wager.
IMHO, in addition to MARS service and traffic handling, every ham should learn CW, packet, and as many other modes as possible, because they are all forms of encryption against untrained reception,while insuring some level of error-correction. The
"Codetalkers" of WWII are a prime example. and you know we are not to use "encryption" according the fcc, right?
WHY? Because they need to be able to intercept communications and comprehend them. After all, "We the people" are all potential "terrorists" in their eyes. Given the right doomsday scenario, our own gubment might actually be our nemesis! Are preparation efforts a matter of life-n-death?
Well --
not at the moment.
