I was looking at building a AX.25 node 10 years ago, with a 15km range on a basic amateur license, with maybe 28kbps. Almost all integrated into a radio with a digital output that cost the same as a PC.
That's what I mean about lack of progress... not much advanced today - it's a bit cheaper and easier, with better range, but no better bandwidth. If the frequencies & range are a fundamental issue, OK. When I was reading 10 years ago there was a strong dis-interest in data from my local groups, who thought it was ruining their voice comms. Still today I find the local amateur radio groups have little interest in packet radio beyond maybe running a webcam over AX.25. The interested HAMs are running community WiFi projects.
