I've been working on a couple mission plans for my XG-100P that I bought recently and came across something that I can't quite figure out. I understand that the ABC switch when programmed to the Channel Bank selection will toggle between banks of channels in the same system or zone (1-16, 17-32, 33-48). However, my preference on radios with an ABC switch is to use it as a low power/high power/xxxx switch so that I can change power easily without going through a menu. The shortcut menu has an option of Sel Chan/Grp that can be programmed and I had thought this would do the same function. But for some reason when I select that menu option I only get one selection of channels 1-16 no matter how many channels are in the system or zone. Is that not the function of that menu? Or is there some nuance of the programming or radio that I am missing?
