Re: Retrofit CAT on older QCX (serial #675) #cat


 

I think it's only on V5 boards. It's on my V5 20m unit, but not on my V4 40m unit.
Look at chapter 4.28 on page 106 of the V5 manual. You'll see the 3-pin header connection on the board edge, at the north east corner of the processor on V5 boards. I'm not sure if or where it exists V4 or before, hopefully somebody else knows this.
