I would prefer to use XASTIR - we may put trackers on the horse riders.

So does xastir gate messages from RF to local port ?

That way I can have perl listening and insert into my external apps ?

Let the D700 operate APRS as normal (TNC in APRS mode) and use an external
TNC, a packet decoder, or a sound card interface to decode the audio output
from the D700 for use by the mapping program.  This does not allow the
program to transmit, but works quite well otherwise.

I use this frequently on balloon chases; the data stream feeding the laptop
for logging, mapping, ascent rate/descent rate calculation, etc is vital,
but I still like to have the data displayed on the D700 as I'm navigating
to the LZ.

Yes, Jason, that's the answer I'm coming around to also. I might eliminate
the D700 altogether and go with a dedicated radio/tracker combination. But,
either way, feeding the radio's RX audio to a sound card interface on a
computer running an APRS client sounds like a good solution. I'll also have
to split the GPS data so the non-APRS mapping program has position data.

Thanks to all for your input!

Subject: [aprssig] qAR & qAr, same igate

I'm seeing some of my packets duplicated on the APRS-IS stream. Packets
come across first with "qAR,CALLSIGN" as the identifying igate, then again
a few minutes later with "qAr,CALLSIGN*" as the igate.  The Q-construct is
different plus there's an asterisk after the callsign.

qAr - Packet was received indirectly (via an intermediate server) from an
IGate using the,I construct.  The callSSID following the qAr it the
callSSID of the IGate.

qAR - Packet was received directly (via a verified connection) from an
IGate using the,I construct.  The callSSID following the qAR it the
callSSID of the IGate.

So... Is this expected behavior or is something else going on?

Do you have multiple feeds for your IGate into APRS-IS?  If so, change to a
single feed.

I am not aware of which server software inserts an asterisk in the q paths.
The software that is doing this is mangling the q construct.  I would guess
that since that software is also reinserting the packet with the qAr
construct, somebody has some bad server software out there that isn't even
dupe checking properly.
