[Elecraft] K3/0 power

[Josh Fiden]

They specify 11-15V, that covers a lot of territory! Seems you could get 
a 12V 1A unregulated linear adapter and just verify that the no load 
voltage doesn't exceed 15V, or a 12V switcher which will be inherently 
regulated. It can't draw more than the 0.9A of a K3/10 on receive. If 
someone can post actual consumption, that would be nice. I don't see it 
in the manual.
