When I was last regularly active, the packet revolution had just arrived (1985). I enjoyed TCP/IP over ham radio in those days. The rise of the internet made the ham radio based comms just a silly toy. Can you imagine having to wait 3 weeks to move 1 megabyte of data over a very lossy radio path? The modem data rate was only 1200 bps with lots of overhead to create the synchronous packets that carried the AX.25 UI frames that wrapped the IP datagrams.
Ok, I just read and understood this passage. I guess I'm a geek? :^)
