I believe that there has been significant discussion about which way round the LC filter should go; ie batt>toroid>cap>vtx or batt>cap>toroid>vtx. Given that I've already made it the way round shown in the diagram, I'll start with it like that. I have the parts to make another the opposite way round which I can do if (when
) I need to troubleshoot. Updated diagram attached....
