Thanks, Don Wilhelm, your intuition was correct: I installed a 120pF
capacitor at C12. When I replaced it with the correct 1200pF capacitor the
frequency display worked!

Sorry, Mike Morrow! The referred post was from David L DuPuy, March 04,
2013. I think you answered him and that's where I saw your name. I'm
obviously not adept at using the reflector - I just discovered there were a
string of replies to David I didn't read.

Sorry, Mike! I'm obviously not fully cognizant of how the reflector works.
I thought the original message I was replying to would be included in the
string. It was back from 2013.

Tom,
Triple check C11 and C12 to be certain they are both 1200pF and that you
did not use the 120pF capacitor for one of them.
Build yourself an RF Probe. The schematic for one is shown in the K1
Manual Appendix on Troubleshooting. You can also purchase a kit from
Elecraft.

Tom,
You cite my name in your post, but I have absolutely no idea of what you refer.
I built my K1 serial 175 in November 2000 and I experienced NO problems start
to finish.
Quote the posting to which you refer, including its date.

I have exactly Mike Morrow's problem, and wonder if he ever got it resolved.
Mike, if you are still around I'd like to hear what your resolution was.
I am awaiting arrival of an RF Probe kit so I can do signal testing to
attempt to trace down my problem. In the meantime I have looked over my

David,
Yes, it does seem to be a problem between C8 and the MCU input on the
Front Panel.
If you are getting good oscillation at the VFO (Q9 buffer) then check
continuity from C8 to the base of Front Panel Q1 - that should give you
a good check on the path continuity. Also check resistance to
9 matches
