[K3] [Elecraft] It have to work better!

Hi,

My spectrum on the line out isn't even as clean as the "before" picture. In
addition to the spur at 12kHz I have spurs at 3.9kHz and 7.8kHz. They, as
well as the 12kHz spur are down about 75dB relative to an above AGC
threshold single tone. They are independent of mode and passband settings. I
doubt if they are audible (I can't hear them), but if a simple replacement
of a jumper could fix it, I would be willing to look at it. Where is W16? On
the picture in Fig. 14 in the assembly manual I can clearly see W15, W17,
W18, all unshielded wire jumpers, but not W16.
