Hoop - I do not have a separate ground for my KX3, so I doubt that’s going to resolve it. I can’t easily check the cables on the back of my K3 as it is on a multi-tier desk shelf and would be ugly getting to it.
The one thing that I have different in my cable scheme is that the line coming from the KX3 ACC2 jack goes into a Y-connector. One side of that goes to the KAT500 PTT and the other side goes into a small homebrew, handheld box with (1) a momentary PTT button and (2) an on-off toggle switch. This affords me the ability to have a hand-held PTT when I operate SSB (seldom) and not use VOX or have to press a button on the KX3. I do notice that you are using an evidently newer version of Fred’s book. Mine is simply titled “The Elecraft KX3” and in that one the diagram is on page 147, but it still marked as figure 9.17. I wouldn’t think the diagram has changed, but maybe if Fred is reading this post he can comment.
