Anyone want to hazard a guess as to what is causing it? I disco'd every switch-mode power supply in the shack and adjacent rooms (couldn't do the whole house as the XYL was home).... EXCEPT my Powerwerx SS-30DV PS running the K3s/P3.
Digital circuitry or SMPS are the most likely cause. See my latest tutorial, linked below, to learn how to tell which is which. 34 kHz suggests a 17 kHz square wave.
