I agree and that really means monitoring decoded packets from the mobiles,
since their performance is worse.
I think some of us get the impression that adding a couple of hops will give
us a better chance of being heard. That is not true in my part of the N.E.
- there are enough digis and I-gates that the first transmission stands a
slight chance of hitting an I-gate directly, and the first hop covers local
information purposes and LOTS of I-gates. The second hop provides
additional coverage along interstates at highway speeds for receiving useful
information. Beyond that, I don't see much point. It is not always
recognized that the RECOMENDED WIDE1-1, WIDE2-2 is three hops.
The truth is that if your first transmitted packet isn't heard, adding hops
isn't going to change a thing.
I am just looking for a tool for people to compare what their purpose for
running APRS is, to what their impact is on the involved digis and igates.
It is about the packets, not the RF network.
