[Elecraft] Problem with KLF1-4 Upgrade

I just completed the KLF1-4 for my K-1.  I chose 40, 30, 20, and 15 for =
the bands.  All resistance measurements are correct.  I have checked all =
winding counts on the toroids.  I have verified that the proper crystals =
were chosen for the bandwidth I wanted, and are in the proper location. =
(80 kHz)  The receiver alignment worked properly on all four bands (I =
was able to obtain good peak signals on all bands.)

40m, 20m and 15m receivers are calibrated perfectly to my signal source =
(ICOM 765)

30m is a problem.  My Icom's 10.110 mHz signal is not picked up at =
10.110 mHz on the K-1. =20

In fact, after some experimenting, here's an example of what is going =
on: =20

Icom 765:  10.130;  K1 receives signal at 10.163.7
Icom 765:  10.135;  K1 receives signal at 10.162.6
Icom 765:  10:140;  K1 receives signal at 10.161.7
Icom 765:  10.145;  K1 receives signal at 10.160.7
Icom 765:  10.150;  K1 receives signal at 10.159.6

I tried playing around with frequency calibration, but as you can see, =
there's something else going on here.

Does anyone have any suggestions?
