Default Re: Trio TS711 & 811

Hoping this works as I think it will, two attached files both in PDF format, ctcss prog is what the MX315 chip wants to see and ctcss actual is what is coming out of the Trio TS711 control board.

I will let someone else check it but it looks like a small re-design of the PCB would solve the problem if I make:-
Expected/Actual
D0 = D3
D1 = D2
D2 = D1
D3 = D0
D4 = D5
D5 = D4
