[Elecraft] K3 REF*CAL issue

[Gary Smith]

I have the K3EXREF installed in this K3. I 
noticed when I clicked on a signal with 
the P3 & marker, the signal was off a tad 
from where it should be. On a hunch I 
checked REF CAL and the asterisk was 
missing. I know REF CAL had the flashing 
asterisk a few days ago.

I measured the signal coming from the 
GPSDO and it was 10.000 0 MHz according to 
the MFJ analyzer. I had recently put in 
filters in the K3, a KXV3B and a KIO3B and 
thought I might have dislodged a coax in 
the K3 so I assured the integrity of all 
the coax cables (I have the new synth 
board). I also assured the K3EXREF was 
seated properly and there were no obvious 
loose components. I cannot get the 
asterisk to flash and the board to lock 
with the 10 MHz signal.

I had to manually calibrate to WWV and it 
was quite off.Does anyone have a 
suggestion for me to try and get this to 
sync? I re-read the K3EXREF  installation 
instructions and the board is nicely in 
place, reloading known good configurations 
with the K3 utility made no change. 

Either I borked a setting somewhere in 
config or I have a failed component.

Anyone have this issue before & found a 
resolution?

Thanks.
