[aprssig] Is there a problem here?

Bruce,

It looks like you followed;
KPC3 Version 8.2(early versions) Settings for WIDEn-N         6 May 2005
http://cadigweb.ew.usna.edu/~bruninga/aprs/kpc3+82WIDEn.txt

Version 8.2 (early releases) UNIQUE Settings:
   UIDIGI  ON,   WIDE1-1, WIDE4-4, WIDE5-5, WIDE6-6
   UIFLOOD  WIDE,30,ID
   UITRACE  SS


6)  IMPLEMENT THE New n-N Paradigm changes.

D.  Instead use the UIDIGI alias list to support WIDE1-1 first-hops for
mobiles and to TRAP the larger N's.  Set UIDIGI as follows:

UIDIGI ON, WIDE1-1, WIDE4-4, WIDE5-5, WIDE6-6

These specific aliases for the larger N's will act like traps because
this digi will digipeat them once and then no farther.


I think including WIDE1-1 may be an error on Bob's part.  Because if a 
station can have a path of WIDE2-2 and it goes through the digi and is 
decremented properly, then why do you want to trap a packet with a  path of 
WIDE1-1, WIDE2-1?

There has been some discussion between local APRS Digi sysops and one
of them made this observation:

I manage the NT4UX-1, -2, -3 digis in the Middle Tennessee area.

NT4UX-1 uses a KPC3 v8.2 and includes the following settings:
     MYALIAS OHX
     UIDIGI ON WIDE1-1, WIDE4-4, WIDE5-5, WIDE7-7
     UIFLOOD WIDE,30,ID
     UITRACE TN,30

NT4UX-2 and NT4UX-3 are both using  UIdigi v1.9b3.
They both have:
     UIFloodCall            =       TN
     UITraceCall            =      WIDE

UITrace, UIFlood, and UIDigi all do callsign substitution


Below is some additional traffic I have observed from my house using
xastir.
It looks like things a working but I don't understand the packets
with WIDE2* and WIDE3*.
Which digipeater sent them?
Should they not have had a callsign substituted instead?
