[Elecraft] new K2 rx audio problem figured out

[Kenneth Talbott]

Reminds me of a PC I was upgrading back when BIOS was in EPROM.  Worked fine
until I put the top on the case.  After several tries I reached over and
turned off the lights.  It quit!  EPROM required light stimulation to work,
it would not work in the dark!

Subject: [Elecraft] new K2 rx audio problem figured out

I finally figured out why i wasn't getting rx audio on my newly built K2.  I
would take it apart, and it would work when I was troubleshooting it.  Put
it back together and I had no rx audio. So, I started putting it together 1
screw at a time and found the point where I lost rx audio.  U6 on the
control board was coming into contact with the board for the vfo encoder.
When i would take the screws out of the control board, it would let it away
from the front board enough for it to work.  
I cut down a couple standoffs to be about 1/16" longer than the stock ones
with the kit and it holds the control board off just enough to no longer
cause a problem.
I sent this to Elecraft support as well.  Maybe something very minor changed
with one of the components nearby that is causing one of the boards to sit
ever so slightly different.
Now I can get back to trying to tune it up!
