While the observation that these fixtures are working for him, I don't 
see any product identification.  And, of course, what matters most is 
proximity to antennas, not equipment (unless, of course, the equipment 
has a strong Pin One Problem).

It should also be remembered that a device can be quiet when working 
correctly, but get noisy when it is aging or getting ready to fail. I 
had exactly that experience a few weeks ago with the knock-off power 
supply for the Thinkpad computer I'm using to do email. It's on a table 
in my living room, 200 ft from most antennas, about 60 ft from the 
shack. I missed the recent 9M4 DXpedition on 160M thanks to a really 
strong noise that had just appeared, and I never found. But when i 
returned from a weekend trip east and plugged that computer back into 
the power supply, the PSU was dead.  And the 160M noise was gone.
