[Elecraft] Problems with K3 s/n 1826

[Phil and Christina]

I got several replies to my query.  I have tried reloading the latest
released firmware, checking the REF and SYN PCBs for shorting and reseating
the oscillator in its socket.  All with no improvement.  The PLL1 voltage
goes above 7 volts in the upper end of 40 meters, and the relays switch
several times as I tune across 40 meters.  The only suggestion I haven't
tried is spreading the turns on the toroid.  Is that my only option at this
point?  Thank you.

  I just finished building my new K3 (all except the 100W amp that awaits
final checkout). The rig seems to power up OK, but returns error messages
when I do the Synthesizer Calibration. It returns Err VCO with E 00374 data
and/or ERR VC4 with E 00039 data. I checked the seating of the oscillator,
the KREF3 and KSYN3 modules and the three TMP cables, but the results are
the same. What is going on and what can I do? Thank you.
