K3 REF*CAL issue

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.

Re: K3 REF*CAL issue - Resolved

I do not know why it was working a few
days back and not working now but I found
the answer revealed on this web page:

http://elecraft.365791.n2.nabble.com/K3EXR
EF-What-am-I-doing-wrong-td7614721.html

It is stated in an addendum that when in
REF CAL & you have the external 10 MHz
source connected, you have to press 2 on
the keypad to enable XREF IN.

By doing so the asterisk started in about
10 seconds and all is well, the radio is
again properly maintaining the frequency.
No idea what made this function stop but
this is what it took to start it again.
