The other day I wrote that I'd fixed my radio noise problem with shielding, and all I needed to do now was "tidy up the installation". That took all day Saturday, and the last wire I hooked up (VOX enable) got my noise back again! Now I was starting to think bad radio, since I'd completely rewired it and had the same problem. But my EE buddy at work questioned my use of one of my shields as a ground wire for the VOX squelch. I came home and tried several other things first (with input from Jeff Scott), but eventually made the shield a floating ground and grounded the potentiometer to the panel, and now the noise really IS gone. So the moral of the story is to follow exactly what the schematic says, and pay particular attention to which end of the shields go where...
