Many people will tell you that such-and-such a switcher is totally
quiet. This seems to vary by particular unit.
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.

I have the same model and it really is that quiet. I bought it to
replace my Astron RS-20 which wouldn't quite handle the current drawn
by my TS-570D at full power (the K2/100 draws quite a bit less than
the Kenwood, however). Running a comparison with my K2 between a
linear supply and the Alinco doesn't show any difference in noise,
birdies, etc., as far as I can tell.
