[Elecraft] New K3 build, LOW LOW sensitivity.

[Hisashi T Fujinaka]

I had something similar, but I was most likely using the wrong antenna.
I heard nothing (the bands were probably dead, and I couldn't even hear
the local AM stations. I checked the weird coax cables, loaded the
latest beta firmware, and then everything started to work. I may have
even worked 3G0ZC (though he first miscopied my call as K7EMS instead of
K7EMI so I'm not all that certain).
