[Elecraft] New K3 build, LOW LOW sensitivity.

[W0MU Mike Fatchett]

Check all the coaxial cables that plug into the boards and front panel.  
Make sure they go the right places.  I would also check the way you have 
decided to handle the coax going to the coax chassis connector SO239.  
There are a couple of ways to do this depending on your options.
