While it is possible your Kx33 has developed a problem, it is more likely
your antenna system has high common-mode potential which is commutating
through the Kx33 to the AC mains. We supplied a mix31 ferrite core with
your supply to make a common-mode choke to help with these types of antenna
system issues. I would be glad to help you, please email our tech support

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.
