I just completed my K3S build and initial configuration. Woohoo. I was
tuning around the bands, and I noticed birdies *everywhere

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,

John, I’ll concur with Larry. I have several D-Link gigabit switches using CAT6
cable with no apparent noise, and I believe their “green” technolog

Thank, all. I may have to look into that. It may jus
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

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?)

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

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

I have seen some cheap "CAT5/6" jumper cables designed to hook the
network device to the jack in the wall, that were purchased on E-Bay.
Nuff said. I suspect they were made with stranded conductor wire which
is NOT spec. They were just a little too flexible.

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
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
you'd be surprised how quite things become. As to fiber, I can't say
