>I don't know if this next change has created was worth doing or

the 6 pair trunk line running between the barn and house (1,000ft)
and terminated them to ground at both ends of the line. My
thinking was that if these pairs were not terminated they might
act as receive wires and re-radiate RF into the active circuit
pair. I know this is a stretch considering the cable is shielded
and buried. It doesn't appear to have hurt performance of the
Ethernet circuit.
REPEAT AFTER ME: THE EARTH IS NOT A SINK INTO WHICH HUM, BUZZ, AND
RFI IS POURED. GROUNDING THINGS IS ALMOST NEVER A CURE FOR ANY OF
THESE PROBLEMS, AND IS OFTEN A CAUSE OF THEM.
