I seem to recall from my distant past, something called "packet radio".
Essentially this appeared to be blocks of 128 byte data in an "envelope"

It wouldn't be beyond the bounds of imagination to encapsulate TCP/IP packets and transmit them. I am not sure of the speeds you might get on SSB but you would at least have a rudimentary net.

Talking about communications .............

Paddy goes up to Seamus and sees him talking to an empty envelope.
"What you doing you daft beggar?"
"It's voicemail innit!"

Wow, good memory RS.....I'm guessing you have an IT background of some sort.

Yest Packet radio does exist. Its not something I've played with but it could create a fairly resiliant communications system if sufficient numbers of stations participate.

I was thinking PSK31 (PSK= Phase Shift Keying) using SSB capable transceivers.
