Hi Greg--

Yes, I've had luck (I'm not sure that it was skill) in getting my rig 
going.  I wound up removing the REF and SYN boards and remaking all the 
coax connections.  I then slipped my business card under each board to 
verify clearance between the boards and the shield.  When I powered up 
again I started hearing traffic.  While I was having my problem, the REF 
and SYN boards were microphonic.  That's why I remade the connections. 
After the "repair" the circuits were quiet, the microphonics gone.

Another thing...when performing the VCO cal that led to error messages, 
the radio went through each cal step lickety split.  Once corrected the 
steps were quite drawn out in some cases, but led to a right and proper 
conclusion.

Right now I'm listening to the Red Sox.  I have never been able to 
listen to this station without lots of noise until hearing it with this K3.
