With tight synchronization (we have a good clock source) and considering the wideband capabilities of the sbitx, we could support multiple simultaneous uucp connections on a single sbitx, for eg., using frequency division, remote stations use one channel each, while the gateway operates in multiple channels inside the 20-something kHz of the sbitx passband, orchestrating the tx/rx time slots.

Hi Gordon,
If later on anyone wants to put up a ham radio uucp HF gateway, As uucp setup is not that easy, I can help with all the uucp setup for remote and gateway stations (I have bash scripts and templates ready) and provide server access to our *.hermes.radio (just choose a subdomain) for initial testing, if needed. This is what we call "central" server, with real IP in the VPS. The "gateway" station just relays emails to "central" email server, and connects (or receive connection) to the "remote" stations over HF. This is the topology I put in place. With VARA and/or Ardop (this is what my uucp bridge supports [1]).
for example, to triger the connection to the gateway (and consequently synchronize the uucp jobs, aka. emais), from a remote station, I just do:
uucico -S gw
where gw is a uucp alias to the uucp gateway nodename, and remember to put the radio in the same frequency of the other station.
the uucp bridge automatically calls the nodename to be connected, which in the case is the callsign of the station, for example, PU2UIT (the nodenames must be valid callsigns for vara and ardop be happy).

Cheers,
Rafael

Rafael, that is very upstanding of you! ?I had no idea that uucp is still moving such traffic over HF radio? (I'm not counting Internet).
Thank you for the education -- I'm benefitting from your knowledge and experience!
The Winlink folks have both a centralized and a decentralized model, so it can gett tricky to count, but the data piles up month over month here:
(click the "traffic" tab):
?(see attachment)
looks like about 76,000 per HF in January
another 45,000 or so over VHF
Total over RF >100,000? or over 3,000 per day.
Again, EVENTUALLY a system will show up that gains even wider acceptance.? ?For all I know UUCP is "there" if you count military? (the above figures have no military).? ? I hadn't thought of that.....
THANKS!? It is great to learn from all the smart people here!
