[Elecraft] K3 with 2m module K144XV

Having tried the K3 with the high spec oscillator and with the external
locking I found I needed the external locking for my 144 digimode qsos.
However my eme shack varies between around 37F and 110F (outdoor garage) so
it is expecting a lot of the internal reference

External locking of the K3 also helped when using the internal transverter
to drive external transverters at 144MHz for 1296, 2304 and 3400 digital EME
qsos

If you lock the k3 reference and the 144 xverter inside the K3 it is vital
to do the mod at

the "Production phase-in is pending." Mentioned on the web site has happened
yet

I need some guidance.  I have a K3 with the optional high stability
reference 
oscillator option.  I have been very pleased with the frequency stability of
the unit 
up through 6m.  Next month I am interested in ordering the K144XV so I can
also use 
the rig for 2m EME with JT65B mode.

Is there anyone out there currently using such a setup successfully on 2m
EME?   Is 
it stable enough as-is, or will I need to also add the K3EXREF and some
additional 
outboard frequency standard?  I would like to avoid involvement with the
K3EXREF 
unless it is required.   I do not plan to use the K3 2m as an IF for
microwave 
transverters, so I hope it will be stable enough on 2m without it.   I look
forward 
to your experience! MNI TNX and VY 73, Lance**
