[Elecraft] [K2] CAL-PLL Question

[David Woolley]

The only reason I can think of why this might apply is if the grounding 
of the bottom cover was poor.  Whilst it certainly can be poor, because 
of paint not having been properly masked around the mounting blocks, and 
I recommend cleaning all paint off, around them, I'd be surprised if 
enough of the induced currents, in the bottom panel, flowed through 
these points to make a difference.
