[Elecraft] KX3 2m external amplifier

[Jim Brown]

On the recommendation of someone on this list, about a year ago I bought 
one of the 350-12 units. It came with no documentation, and no 
certification of compliance with anything. It is VERY NOISY, and nothing 
I have tried has been able to make a dent in the noise.  Multiple chokes 
on AC, multiple chokes on DC, and bypass caps on both AC and DC. It's 
currently sitting on the shelf in my store room.
