I plan on making a video on a simple setup of the Loupedeck Live with MSFS, and if I can work out how this is supposed to work I can simplify the knob use from four to two. Even if this is just confirmed as no longer being functional that would help.

I'm trying to tune the G430/530 radio using keyboard, but I can't make sense of the controls. As I understand it "COM RADIO" is used to toggle between "whole numbers" and "fractions", and "+/-" is used to change the values. I believe "+/-" is literally PLUS and MINUS. So I press "C" for "COM RADIO" and "CTRL+ NUM PLUS" and "CTRL+NUM SUB", but nothing happens. The web search results I've found on this subject are quite vague, but suggest that the above should work. And then we have "NAV RADIO", which apparently performs the same role for the nav tuner, but by default "N" also maps to "DISPLAY NAVLOG", which suggests these are neglected functions. Any help would be appreciated.
