Yeah, me too. I bought it because I thought it would be "super clean"
and really small. But its contribution to my problem was pretty much
unarguable: Plug it in and I hear noise. Unplug it and I don't hear
noise. The instructions that came with it specifically stated that the
Kx33 should be placed the full length of the DC plug/cord away from the
transceiver. I did that but it didn't work for me. I tried different
outlets around the house too. I put chokes on it. No joy.
My post is not a complaint about the Kx33 mfgr, or the Samlex
Corporation or anyone else. Maybe it's my transceiver, maybe it's my
equipment, maybe it's my utility service.....I'm not qualified to say or
knowledgeable to analyze.
I simply wanted to suggest to others in the Elecraft family that if they
have "noise" it might be right under their nose and worth checking out
vs. blaming propagation or the next door neighbor ;-)
P.S. - My "noise problem" is about two years old and coincides with the
purchase of my first switch mode power supply. I had a perfectly good
linear supply made by Astron but I deemed it too big and klutzy and
dumped it. Another one of my great decisions....

I'm really surprised you had an issue with the KX33 supply.
