Another short post as I try to get on top of everything at the moment to say that on our last trip to Arkaroola we successfully tested the UHF packet radio functionality over a distance of about 4km. This was from the observatory ridge to Coulthard's Lookout.
With the setup we were using, we had about 50% packet loss, and jet LBARD kept persevering, and delivering MeshMS messages within a minute or so.
We did see a recurrence of a bug affecting a corner case of LBARD operation, where sometimes you have to send a 2nd message to flush out a stuck first message. However, this should not be too hard to fix.
This weekend I fly out to Samoa to meet some folks there to talk about our AusAID / Pacific Humanitarian Challenge grant to run a pilot using Mesh Extenders there, and it will be nice to show off the UHF functionality while there.
