Mostly electronic communications for survivalists and other off-grid/down-grid types. Occasional social commentary, and general self-reliance stuff.
I like old Heathkit SWR meters. I have them in my shack. They work well and you can get the manual and easily repair them if needed. I have bought very nice ones on eBay and also qth.com. You can see them at local Hamfests from time to time.
