[Elecraft] (OT) - Unplanned Discovery

[stan levandowski]

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....
