[Elecraft] Noise Power Ratio and the K3 with new synthesizer?

[Tony G6GLP]

Hi Rick,
I have had similar types of issues and found with the help of Elecraft 
Support that the problem was the seating of the AUXBUS cables. Mine 
would seat one side or the other but not both. I used a knife to par off 
a little notch in the cable housing to allow it to fit over the 
retaining nut. I even tried to line the nuts up so the sides were 
vertical but this didn't work.

Hope you find the problem soon its a great system when all working together.
