[Elecraft] Is it my KX3/antenna or is it lousy band condx?

[Bob McGraw K4TAX]

Not exactly correct.    I have 2 which do not, as I measure and listen, 
create any noise.   On the other hand, I purchased a "deal" for a 13V / 
30 amp supply.   It measures.......well it will never be in or around my 
house as it generated lots of noise from 1 MHz to over 100 MHz.   I was 
suspicious when I couldn't find a Part 15 label on the box.  But after 
all, new shipped to me was less than $20.   Guess one gets what they pay 
for in terms of quality.
