And then the TNC died!
So that's the end of APRS (for now). I could try using a sound-card based TNC (i.e. Direwolf) but I decided not to. I've decided instead to use the 2m FM radio for Allstar (or SVXlink) instead.
I messed about with an old Allstar image already installed in my Allstar node that I found in the shed. Then I flashed another SDcard with an image with an install of SVXLink and experimented with this…
Then back to Allstar.
I think (for now) I'll stick with Allstar. And perhaps do some experiments with bridging between analogue Allstar and DMR (and might look into YSF bridging too).
I started this with a dive into DMR bridging with DVSwitch - and started to document it here : GM4SLV Allstar 2025
