CHIRP

Here's a screen recording of the problem.

Thanks, the VX-6 driver doesn't support cross mode, so the problem is really that the UI shouldn't be showing you that column. When you try to select a cross mode, it tries to select Tone Mode = Cross, which it can't do.

If this is something you need, I suggest you open a feature request so someone with a VX-6 can work on adding that support.
