I used to be into Shortwave back in the 80's when it was still had great stations to listen to. Still have my gear but it's not operational.
I have used ham gear years ago and enjoyed it but when I got out on the road I was required to have a CB but I did take it a step further and went side band because you have more channels ( upper and lower ) and has better reach. I and the very few friends I have left do keep walkies on hand and using AA batteries because with everyone running around in electric cars, planes and trains recharge may be illegal along with paper maps and a good old compass ( mine is about 50+years old and still works. Of course I have a small mirror but keep in mind survival means heat and some times folks forgot fire and the best thing I have found to have in your gear is your flint unopened Bic lighters and the most reliable tinder is medicine bottles or small plastic bottles with screw on lids with cotton balls smeared with Vaseline is a quick start, I had these when I got caught in bad snow storm in the Tetons.Not sure I want to go with Ham radio but have been thinking about a CB radio for the truck.
