[Elecraft] Silent power supply for a K3s

[Bill]

I have several Power Werx switchers and prefer them for their size over 
the heavy analog supplies. Fans are not a problem (actually, I hear 
nothing from them at all) - IF you design your radio desk for proper 
equipment placement. Place the power supply at your right hand - and you 
WILL hear noise, XFMR, fan, etc.

It is amazing what proper station design/construction can do for making 
silence. Open faced metal shelving and bare desktops don't cut it.

Just for grins, I put one of those Nanoxia fans in my IC-7300 and 
silenced it completely. Worth the few dollars and effort. No temperature 
changes noted. Hmmm - KPA500?????
