Hmm,

funny, I owned the same model, but mine wasn't silent....worst on 80, less 
worse but still no good on the higher bands. It made even my AO40 
downconverter (2.4 GHz to 144 MHz) unusable, spiking caused the mixer to go 
bazurk...
Friend of mine also has this one, same problem.

I've switched back to linear power supplies.
