You're certainly not wrong about what you call "grounding" and I call pin 1
problems. :)
I do have an HP 3590D spectrum analyzer sitting in the shack, and put a
simple loop on it to look at 2nd harmonics from my Ten Tec 425 amp and 160M
vertical. It was about -44 dBc when I started, and I got it down to the rated
-50 dBc by doing nothing more than changing coax jumpers.
Now, I trust your engineering, and your measuring may be better than mine. :)
