> isn't easily triangulated? Depends. Anything with high enough power is triangulateable, if you have either enough time, or enough listening equipment. also what precision are we talking about? on longwave you can bounce radio signals about quite a lot, but you lack bandwith, and the antenna are huge. If you have a high band width transmitter, and you are doing async transmission, ie send a message when you are far away, then its not as critical.
