@F4FXL @aprs I wrote an implementation of AX25 in the days of packetbbs were widely used - before websites. Now I find that #AX25 and #packetbbs aren't dead, just overshadowed. I've managed to get #direwolf running on HF via an IC-7300.

That was the easy bit. As is the way with all software, there's understanding the layers, so as well as exploring Direwolf, I need to find an #AX25 tools tutorial. Thanks for your tiny example - these really help.
