[Elecraft] KX3 high pitched hum on headphone jack

[Stephen Selberg]

I had that same garbage power supply. Got rid of it and stuck it in the
garage to collect dust. It was causing all kind of noise in the shack. I
bought the alinco switching supply and have been very happy with it. I use
it primarily to power my TS-590. I like it because you can vary the voltage
between 5-15v. It's the DM-330. Very easy to pack up and take on the road
with me.
