Literally me right now, got my first SDR less than a month ago because I wanted to have an FM radio for emergencies and I am designing antennas and studying for my amateur radio license.

If you want an FM radio for emergencies, get a battery-powered analogue FM radio, not a computer running SDR!

Just make sure you have batteries/a way to run it!

When we lost electricity for 1.5 day here last month (Spain), I thought I'd be clever and use my SDR too, but since we didn't have electricity at all, and none of my laptops were charged, I was out of luck. Wife's Macbook had battery available, but since I never used it with her Macbook, of course it didn't have the software/drivers needed, and the internet didn't work as all ISP equipment was also without electricity. Ended up listening to the radio in the car which was more than cumbersome :/

TLDR: get a shitty battery/hand-crank powered FM/AM radio for emergencies

Remember schematics for radios powered just by radio waves. No need for battery or hand-crank. That was in some old books, but never managed to build one.

Good luck with the license! There's lots of people on Mastodon that chat about radio stuff.

Packet radio, srsRAN, LoRA, Doppler Radar. So many fun things to do with SDR.
