Re-read your original post that got me going with APRS. Even though the messages sent through the server got to Outnet and back, it was more interesting pursuing this approach. At the moment am looking at YAAC again to see how I might integrate with the current setup. The Pocket Packet to Baofeng is a bit clumsy but works. However I use PTT since the VOX doesn't seem to be sensitive enough. It's fun to see the whole chain of events work.
BTW I now address anything going to OUTNET with APOUT.
I have been an avid SWL for decades and all of the latest digital modes and learning to decode them is a fascinating part of the hobby. I don't do typical ham stuff, have just the Technician License but it does give access to things like APRS.
Have been following the R Australia issue. Hope it can come alive on SW again -- even if only in a limited fashion.
