Yes, everything that radiates around your house and even outside your
QTH for up to several miles will basically be additive to the noise
floor. Take away the electricity from a couple of miles around and

Bob,
Could it be that fiber optics cable is the reason? Not much RFI from
photons. Not everyone has access to fiber.

I have seen some cheap "CAT5/6" jumper cables designed to hook the

Nuff said. I suspect they were made with stranded conductor wire which
is NOT spec. They were just a little too flexible.

I'm confused by this statement. CAT5, 5e, and 6 are four pair cables.
The pairs have a tight twist but each has a differe

The answer for me was shielded CAT 5. Different switches just produced
noise at different places. Was also greatly affected by devices plugged in.

Bob,
Just a quick question here. Are your power feeds Romex/NM, or is everything
run in conduit? Would/could that make a difference (i.e. can electrical noise
from a device such as a modem/router or its power supply be radiated via the
home's AC wiring?)

I am of the opinion that most if not all the issues associated with
"noisy networks" is cheap switching power supplies that comes with the
equipment. Cat5/6 cable in and of itself is pretty immune to noise
pickup because of the twist in the conductors. That twist is there to
knock down crosstal

If changing the cabling was the solution for your "birdies" then it
would appear the issue was not with the switch hardware, but with poorly
constructed cables.
There are a LOT of CAT-5 and CAT-5e labels on cables out there that
simply aren't. There's a list of specs involved, fairly lengthy one,
