[aprssig] Packet routing, path specification.

With these TNCs setting UID ON WIDE1-1,... causes the fix that _does_ allow
their continued use.  They are still in service as the primary digis
supporting the "New n-N Paradigm" across San Francisco and Monterey Bay
areas in NCA.  Works very well, no dupes.  Your frustration on this point is
not merited.
Decent suggestions at http://nwaprs.org
Bob has already provided workable solutions in response to Pete's message
saying people are "thwarting" the system.  While I do not believe we have
large numbers of users intent on thwarting the system, such users could
thwart _any_ system.  Rather, I think it's far easier to complain or feel
frustrated than to produce the real _interpersonal_ effort required to
improve the knowledge of our fellow amateurs.  But that friendly work is not
really difficult, only personal!
Talk to your "thwarters" on Field Day!  hi
