My Alinco DM-330MV (32 Amp) switcher sits right next to my K2 and works
fine. Do I just not know what to listen for? What should this ps sound like?
This particular model allows me to adjust the noise frequency to move it out
of the way if necessary. I've twisted that knob from one stop to the other
and I don't hear any difference on the K2.
