Right, in an actual incident we would only need to receive.  But, how
would we know ahead of time that our equipment would actually
detect the interference, and how would we practice using the equipment
to actually locate something?

My reference to the woods regarded where many hidden transmitter hunts
are held.  Setting up a jammer that wasn't near anything worth jamming
would still be illegal, no?  Besides, it would have to ID every 10 minutes, 
which would kind of give it away...
