[Elecraft] K3 Powers Off On Its Own

[David Hachadorian]

On one of my K3's the Powerpole receptacle got flaky. Turn the radio on, 
and then wiggle the plug  to see if it drops out.  I resoldered where 
the receptacle pins mate with the circuit board inside, but I still had 
to use a tie-wrap to hold the plug in a certain position.  I'll fix it 
the right way one of these years.

Good luck!
