I am trying to link my PW1 and 6500 for auto band change. I have downloaded ddutil v3, and I have a usb based serial to civ adapter (produced in UK by G4ZLP) which I assume to be equivalent to the Icom CT17. So far no success but not sure if I have all the settings made properly. Does anyone have such a link working properly? Or can advise how to set up ddutil.
