Several years ago, Howard sent me one to test. It was very quiet when
only powering my KX3 on receive, which draws only about 150 mA. When I
used it to supply something that drew 4A, it was noisy. So the question
is, are you using it power anything else in addition to the KX3?
A good common mode choke made by winding the right number of turns of
the power cord around the right #31 core should suppress the noise. You
should also make certain that everything in your station is properly
bonded. See http://k9yc.com/GroundingAndAudio.pdf You should also make
certain that if you are using an end-fed wire antenna that you have
provided a suitable counterpoise for it.

When I plug in the PAE-Kx33 power supply to my KX3, I get a huge amount of

Any suggestions?
