When I was a teenager I used a $10 shortwave radio for SWling. I think it could take 5V for external power from eg. a hand crank if you really wanted that (although nowadays I'm sure people have solar panels laying around, they're so useful for things like boats etc.) I don't think you need anything fancy.
