I bought three, two for myself and one for a friend, two of them were very 
quiet, one was noisy on 160 through 20 meters. I did the following and all 
units were quiet;

1  Place the unit about 3 feet from radios
2  use tightly twisted #10 wire to go to a RigRunner distribution panel
3  Put a ferrite core immediately at the output of the power supply with 3 
turns through the core
4  Put .1 uF, a .01 uF, and a .001 uF capacitor at the output of the power 
supply.

Your mileage may vary, I have heard from other persons on the QRP-L 
reflector that did and some that didn't have noise.

I was told by someone who owns a Samlex, and he said it's identical to his.
