[Elecraft] Silent power supply for a K3s

[Bob McGraw K4TAX]

I find Mark's point very important.   Obtain and use a supply which is 
more than adequate for the service or load.  Thus a 25 amp supply 
feeding a radio drawing 20+ amps will need lots of cooling.   This is 
not the way to do it.   Get a 50 amp supply for a radio drawing 20+ amps 
and the fan(s) will likely never come on.     Go the cheap way and get 
the cheap results.    Do it right and be happy.   Don't be a cheap ham 
and then complain about the product you purchased.

There is more to choosing a power supply than volts and amps. How about 
duty cycle?  And CCS rated supplies vs. ICAS rated supplies.   Humm.......
