A Yeasu wrapped in a mylar bag with layers of plastic all inside a small galvanized trash can would likely work. Just have a small solar charger in the can with it and have the radio preprogrammed and ready to go. Get a better antenna and you should be able to communicate to your local Elmers. I'm still studying for my license so for now I'm just listening but I grew up around radios, my Dad put up commercial repeater towers. I remember him showing me how a squad car two way could light up a florescent light tube by keying the transmitter. There's a lot of juice going through the air and apparently that's how an EMP would work but much higher energy levels, enough to fry integrated circuits. Something like touching a welding arc to an antenna. I remember watching a thing about the NORAD bases, the entire strucure is wrapped in copper screen to sheild from EMP. Again, I'm no expert so do your own research I would hate to be responsible if my info failed you.
