[aprssig] Point-to-point telemetry addressing

Michael, your neighborhood has a lot of mis-configured stations and
digipeaters, and stations with obsolete settings.  It's a shame that their
settings haven't been optimized because it makes using the VHF network more
difficult and because it makes understanding how that network is operating
more difficult too.

Although the KB2FAF-10 IGate is porting what it hears on VHF into APRS-IS
(Internet Stream), there's no indication that KB2FAF-10 does any
_transmitting_ on VHF.  I'd suggest trying to digipeat through the nearby
KB2LUV-1 station instead of KB2FAF-10.
So then,
W9IP-1's path to W9IP-2 would be APRS,K2AMB-3,KB7LUV-1
W9IP-2's path to W9IP-1 would be APRS,KB7LUV-1,K2AMB-3 or maybe simply
APRS,K2AMB-3 would work.

A couple of points.
Michael, your W9IP-1 position shows as being in an exactly the same location
as K2AMB-3 and W9IP-1's map symbol shows as an obsolete type of digipeater
too, but W9IP-2 is not producing a valid position packet at all.
RELAY and WIDE and TRACE are long obsolete (at least in North America).
Courteous modern routine (generic) digipath, Base:WIDE2-2
Mobile:WIDE1-1,WIDE2-1 .

Scott -

I forgot to mention that I'm using a homebrew program.  It sets the UNPROTO
address list of the THC (A TNC-2 clone), then sends the message as a UI
packet.  If I don't include APRS as the first entry in the address list,
nobody will digipete the message.

However, neither of these appear to work.  The only addressing that
seems to work is APRS,WIDE2-2, but that only works from time to time,

APRS should not be part of your path, unless you're using a program that
takes the first entry as the destination callsign.  I forget which ones do
that.  Do you have an example of one of your packets after it's been
digipeated?  That might tell you what's going on.
