[R-390] powerline noise - it's dead, I've killed it!

Mon, 07 Apr 2003 19:48:50 -0400

All: I had a Linksys hub that trashed everything across the HF spectrum.  I
got a 1-amp linear regulator board (kit mfr beginning with V...can't
remember the name but I believe it's German.  Vellemann???) and put it in a
small box with a Radio Snack 6-volt transformer and such, and set the device
to produce what the original switch-mode wallwart produced.  End result...NO
NOISE anywhere.  For the Linksys stuff, and similar, that's an easy fix for
switch-mode trash...

In retrospect, I should have suspected the network all along.  But I put it
in when I was relatively inactive as an SWL and never put two and two
together.  The CAT-5 wiring stuffed into this house made an excellent
antenna for the crud the hub generated.

This Linksys unit is definitely defective.  I have other Linksys equipment
in the house and they all appear to be dead quiet.  The defective hub puts
out one hell of a harmonic loaded buzz in the 410-430 kHz range.
