Just picked up an Xiegu G90 and was wanting to put the squelch on the MFK knob (as 2nd Function, short press to activate). Every tutuorial I see, already has that on the knob, it seems. Mine has: 100K adj. and 2nd Function of Bandwidth adjustment. But the instructions I'm following don't seem to work. I'd like to have 1st Function: 100K adjustment 2nd Function: squelch When I long press the MIF, any change I make only affects the 1st Function. Nothing I do changes the 2nd Function. Suggestions? Mike PS: I sure wish China would learn to write good manuals.
