SDR maybe useful if you already got a bunker to host and power the equipment needed. But if you already got a bunker, why not install a more powerful station?

SDR maybe useful if you already got a bunker to host and power the equipment needed. But if you already got a bunker, why not install a more powerful station? Realistically, you probably want to have something mobile and not power-consuming, plus a solar panel (or any kind of generator). So maybe a set of LoRa device and/or goTenna, HAM radio + backup batteries, and AM/FM radios. Or maybe just HAM radio + backup batteries. I think I might just reignited my desire for a HAM radio license...just kidding, I'm living in a small city of 3KM radius, I'm will not survive the fireball if a nuke decided to hit us. So good luck for you, I guess.
