[aprssig] APRS in Dallas

[Joseph M. Durnal]

I've been traveling a bit more than normal lately.  I should get a D7.
 I miss APRS when I'm on the road.  Right now I just take my VX-170.
I will probably be adding an opentracker to my collection, but then
I'd need a laptop and a lot more wires which probably wouldn't be good
for the carry on bag.

I wasn't to far from Dallas in Ada, Oklahoma.

I was on the sky-tram (roof of the airport) with clear view of the ham radio horizon in all directions...

Or saying the DIGI was a "DIGI".  Or that it was an APRS DIGI or that it was a KPC-3 8.2.  All of this is already encoded elsewhere in the packet.  The intent of the TEXT in a DIGI (or any station for that matter) is to provide some USEFUL info, not redundant info.  Each digi has at least 20 bytes that can be viewed by everyone.  THink of how they can best be used for ham radio...
