I'll take my 50mw 50.080MHz Altoid box radio tomorrow and use it as a test signal, and put one of my handi-talkies in the pressure cooker with the magnet wire antenna and try it from 100 meters and see what the results are.
I'll consider it good if I can break squelch on the handi-talki.
I'm betting it will work. I've done a lot of QRP mobile and field.

You are a gem! What would we do without FR?
Are you going to have 6 ft. antennas at both ends of the link? And I’m assuming you can coil up those antennas a bit to reduce their size. Think about how the mad bombers would have managed this inside a backpack and on their person.
