I had the same issue. It was caused by my Powerwerx SS-30DV. After trying a
number of things to mitigate the noise, I ended up replacing the power supply
with a Samlex SEC 1235M. Noise gone. Problem solved.

I am seeing a repetitive RFI source every 34kHz from somewhere less than
20MHz thru 30MHz plus...
See attached image. The amplitude alternates high/low every other
appearance. The overall amplitude is higher or lower depending on the
location within the spectrum.... Almost a sine wave function with a
VERY long period.
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.
Don't have a battery to run the radio on right now...
