For trail work at slow speed this isn't bad but in a tactical situation (like race support or emcomm), knowing exact locations for everyone helps directors know who is close or not to an incident. The Yaesu system also has a group thing where all the members of your group show up in a list with updated positions periodically even if they are not transmitting. The radios essentially query each other to keep the table up to date.
so how would this work- would I see you in a little map on the same display? or would i have to have a separate screen or laptop to display that info? A little GPS of the trail with bouncing dots sounds beyond awesome...

And what do you mean about "just your callsign in the header.." are you saying when I transmit digitally you'd see my callsign on your radio? So kinda like caller ID? wow.
