Jim, I have a Rigol Spectrum analyzer (again I'd have to look up the 
model #) and I don't hear a sound on any bands, 160 through 440.  OTOH I 
do have one of their heavy duty, adjustable, 30 or 40 A (I'd have to go 
look)switcher, lab supplies and it makes the typical switcher noise 
"when starting."  Once running, it'll power any of my 12VDC rigs, 160, 
440 with nary a peep.  I have an 897D so can get any mode on 144 and 
440. Not the best 144/440 rig, but it works.
