[OZAPRS] on community APRS

[Glen English VK1XX]

Hi Matthew

I'll get comms here while it is relevant to the forum.

Am also doing midband VHF APRS....

Yeah in the old days, you'd work really hard on modem symbol recovery
loops, optimizing this and that. these days I just run 8 parallel modems
on different phases and pick the modem that produces the correct CRC...

I can actually understand the Direwolf source , and the group and
support is excellent.

I'll keep you abreast on the STM32. I have full pick and place line here
so can build stuff...
