----- Original Message ---- From: Scott Miller <scott at opentrac.org> I figured a crystal-controlled rig would be better for simplicity. But you're right, doing data at low S/N isn't going to be fun, and AFSK over SSB introduces frequency stability concerns that you don't have with FM. If the remote stations are transmit-only, though, it seems to me that you'd only need a small number of more capable RX stations. --------------------------- 1200 baud on SSB works just fine. In the early days of PropNET, we used to have people all around the world on 28.128 USB AX.25 at 1200 baud. It was quite forgiving for tuning purposes. Certainly more forgiving than 300 baud is.
