[Elecraft] Power supply for KS

[Rick Bates, NK7I]

Wayne has said that 14.2V is desirable (as read on the display, so 
~14.4V at the source AND the input connector at the radio).  This 
provides a more clean signal.

It's also important to not allow voltage sag under load (for the same 
reasons).

Just make sure that if the power supply causes noise, that you can 
return it without cost.  Then your decision is switcher vs analog, each 
work well; each have issues or 'features'.
