[Elecraft] K2 Initial Power up

[Don Wilhelm]

Nate,

Check to see if you have Control Board U6 in the right way 'round.  If 
it is backwards, the symptoms you report will be present along with the 
5 volt regulator getting warm (hot if you leave it that way enough time).
U6 usually survives that abuse.
