         There's another possibility, though, one that I've done from 
time to time -- use that one hop path to allow my home station with 
50+ feet of coax to hear a digipeat of a packet that my mobile 
heard.  My mobile used to hear ISS and PCSAT and my home would not 
reliability do it, but turning the dig on in the car allowed me to be 
inside and see those stations.

         And yet another possibility is to allow the transmitting 
station to see his OWN packet come back at him, thus showing that he 
was heard.  This is pretty handy, too.
