Bob,
Could it be that fiber optics cable is the reason? Not much RFI from
photons. Not everyone has access to fiber.
Recently our commercial power was knocked off by a falling tree so
only I had power (from my Honda Gen) and I noticed that the "RF
world" was a whole lot quieter. One could surmise that this was due
to no line noise, but also no neighbors had power for their wi-fi's,
plasma TV's, grow lights, garage arc welders, etc.
This also told me my home appliances were clean! So that limits what
one can do short of hooking up dummy loads for antennas. On HF you
might try RF filters but that is not a smart thing to do in front of
eme low noise figure preamps (i.e. filter insertion loss translates
directly into higher NF and the sensitivity of your eme system is destroyed).
Be nice to have fiber...maybe we'll get it about the time you install
quantum-linked internet. ;-)

Our system arrives with fiber underground to the box the TELCO provided
on the end of the house.

To me it is very puzzling why so many seem to have issues and a few do
not. I could elaborate about station equipment connectivity. It would
most likely start a controversy as to what is correct and what is
incorrect. My point, if one is having issues, this should trigger a
thought to investigate how and what is configured with the station. In
some cases, I'm sure certain equipment is more prone to generate
noise/birdies than others.
