[Elecraft] KIO2 not working

[james at kurtadler.com]

Wow you guys are good! Heh, can't believe I missed that, but then again 
I build better than I diagnose! It was L2. No continuity at all. I 
checked the other inductors and they are fine. I called up Elecraft and 
tommorrow they will be sending a new one (or two) in the mail. Hopefully 
that will solve the problem as everything else voltage-wise checks out 
as it should. Thanks to all and I will update when I get the replacement 
part installed. 73,
