Hi Simulant
I did run it from a console, but the logging information was not useful. I'm not a FGFS expert, and can't understand what is happening reading the code, so I do not think that collaboration would be helpful. It may possibly be that I just have the Radio Panel, but not the Multi-panel.
BTW, I have a earlier program that handles the Switch panel, although configuration is quite difficult. I'll probably convert that to the Rust language to achieve OS independence.
