I am happy the 9PX driver gets you past the issue. However, I am concerned that you will have issues with the settings tab not matching the radio as the 9PX updated some features that affected some settings.

Specifically, settings like PF3-KEY, Screen Mode, and maybe sometimes the CID values can be different than the earlier 9 series. If you ever experience the Settings Tab blank out, that is likely the reason. I would be happy to make the adjustments to the 9D Plus driver which is most likely using the same memory map and settings values as all other 9 series radios except for the 9PX.

To use this patch.
Save it on your computer
Help -- Enable Developer Mode
File -- Load Module
select driver file from where you saved it.

Use as normal with the radio selected as KG-UV9D Plus

Let me know if this works for you.
