I am unable to use VarAC native radio control in v3.4. I can select my IC-756 Pro III radio, test frequency change and PTT just fine. When I try to Save & Exit the options, I get a message saying VarAC doesn't have write permissions. Obviously, it does - logs and/or received files are written to the proper directories. What am I missing?
BTW, Omni-Rig works fine. I am not sure I see a reason to implement the built-in radio controls.
