Thanks for all the information, guys. If I ever find myself in a city without power or communications, I'm definitely going to rely on you to figure out how to let me communicate.
The one piece of not-so-happy news is that Perry is a short wave radio hobbiest. I was planning on having Andy Tucker come in and set things up (the guy who knew how to use the old printing presses in Operation Blackout). I figured it was the type of thing he would know about - even though he was half-deaf. Maybe I can still find a way to fit him in.
