[Xastir] Xastir not digipeating, can't figure out why.

[Aaron Vogel]

Hey there, I've gotten really far and just have 1 hurdle left to my goal of
creating a fill-in digipeater, but it's an important one: I can't get
Xastir to digipeat. Hoping the list can help.

Setup:
RPi 3 B running Jessie
TNC-Pi from TNC-X.com
Baofeng UV-82
DB-9 to Baofeng TNC cable

Situation:
Xastir is setup fine (other than not digipeating).
I have configured the TNC-Pi and APRS.fi as interfaces.
I can manually transmit and stations nearby hear me (verified on aprs.fi)
Looking at the log files or packet data display I even see the
automatically transmitted packets going out about once every 30 minutes at
the moment from my station.

What I don't see is any kind of digipeating going on.

Here's a screen grab of my interface setup for the TNC-Pi:

And here's my xastir.cnf file:

I don't think there's anything else I'd need to set but obviously I'm
missing something.

Thanks in advance,
Aaron
