KX3 Macro Problem

[K22]

Hello all,

I woul like to add a macro to toggle the ATU on PF2, but unfortunately I haven't even gotten as far as reading them from the radio :(

When I press "Read Macros 1-8 from KX3" all Label & Command boxes are filled with strings of ÿÿÿÿÿÿÿÿÿÿ

Any thoughts on why this is not working?

Thanks All
