Bob,
I skipped Dayton this year.
It is true that there is no stock means of syncing the XV144 to an
external standard.
A few owners have said they were successful with replacing the crystal
with a circuit that is synced to an external standard, but I now nothing
of that implementation. Perhaps someone who has done it will speak up.
How is JP9 jumpered in your XV144. For maximum stability, the jumper
should be between pins 4 and 5 (no other jumpers). With that setting,
the crystal oven will be powered as long as 12 volts is applied to your
XV144 - don't turn the power supply off! Let the oven warm things up
for at least a half hour (longer if possible) and then calibrate. It
should stay close on frequency.

My K3 has an external "Leo Bodnar" reference [REF * CAL] . Thus the K3
is accurate for my EME and MSK144/FT8 adventures on 2m.
Except: I discovered that the XV144 is not synced with anything.
The K3 Menu/Config DOES allow for "XV1 OFS", and knob turning, to set in
a "Calibration" value.
As I do not have the luxury of a bench of accurate test and calibration
equipment, I am unable to get the XV1 to get and remain near to accracy.
Some friends told me they "Thought" that the XV144, external
Transverter, does have the option for an external GPS REFLOCK as the K3 has.
Calls to Elecraft revealed, other than friendly people, that there is no
way they know to REFLOCK the XV144 ..
So List people, figuring I do not want to calibrate every day, how are
you users of XV144 keeping your other friends from naggin you every day
and every time you call CQ on MSK144 ??
Hoping Don, W3FPR, will have some time after hectic daily Dayton
HamFest schedule to answer too.
