[aprssig] WIDEn-N and New-N packets on the air

Due to the different TNC's on the air, and the fact that
some have and some have not yet changed over to the
New-N paradigm, I have prepared the following summary
of what you will see on the air from KPC-3 digis. In all
cases below, the original packet transmitted is
A- WIDE1,WIDE2-2 and the packet dies after 1st hop if this
is an old KPC3 or 3+(v8.2) with UIFLOOD supportin WIDEn-N
B- DIGI1,WIDE1,WIDE2-2 and the packet dies after 1st hop if this
is an old KPC3 or 3+(v8.2) with UITRACE supporting WIDEn-N
if this is a KPD-3+(v8.3) with UIFLOOD supporting WIDEn-N
DIGI1,WIDE1,DIGI2,DIGI3,WIDE2* if this is a good
KPC-3+ versio 8.3 or 9.1 with UITRACE doing WIDEn-N
*** This is the desired New-N Paradigm result ****
DIGI1*,WIDE2 in an old KPC-3 or KPC3+(8.2)
that has the WIDE1-1 fix in the alias list but still is
only using UIFLOOD to support WIDEn-N
DIGI1,DIGI2,DIGI3*,WIDE2 in a properly "fixed"
old KPC-3 or 3+(v8.2) that has placed WIDE1-1
in its alias list.
**** This is the DESIRED WORKAROUND RESULT
**** under the New-N paradigm for these TNC's.
Notice that the trailing lack of a * on the WIDE2-0
which is not fixed, but this should not be a problem
unless it is picked up by an improperly set UIDIGI ROM.
Now, the ABOVE are only for KPC-3 results. There are
another several possiblities for improperly set up UIDIG
ROMS for which I have no experience to comment.
I hope this time I properly detailed what one could
possibly see based on what the KPC-3 digi will do.
PLEASE, lets everyone get ALL digis set properly to
the new-N paradigm so that all these permutations
will go away and we only have options D and F
as the standard New-N TRACEABLE paths.
Hope that helps...
