Kevin, you can take Evan's proposed flow to the bank.
When I built my V4 I was sure I was smarter than this. Turns out I am not. Nor is most anyone. hahaha.

The combination of uBITX with Nextion Screen makes a Dreamy Radio. Think of it as a FLEX6000 killer. hahah.
I suspect that with the V6's new organic screen and some solution to CAT control, the case for the Nextion screen is weakened a bit, but you will have fun in any case.
