The plot thickens, this afternoon, I turned it back on.
The noise is back. Ok, start unplugging things from the
in and out ports.

Looks like extension 24 and 25 are the culprits. Those
two go via a Cat-6 cable to two phone jacks at the work
bench.

I'll see about finding some ferrite to see if I can tone it
down a bit.
