[RFI] RFI cured with 1/4 wave wire

[Gerald Wolczanski]

"RF ground"

OK - I get your point.  When I say "RF ground" I mean a place for
antenna return currents to flow

Back to my original question:
"Why did the installation of a 1/4 wave wire attached to ground, at/near
the coupler, cure my 30 meter noise problem?"

My guess:  It provided a low-Z ground at that frequency, not unlike a
"tuned ground"

as for:

I see I have a "pin 1" problem (Elecraft K2) and probably numerous other
grounding/bonding things I need to look at.  I will do that in the weeks
ahead, but right now, I'm clean as a whistle.
