[Elecraft] 2 M Transverter Stabliization

Wayne, Eric,

I'm referring to some concerns described by inputs to the Elecraft 
Reflector, about not only the stability but also L.O. calibration of 
the 2 M xvrtr, K144XV and probably the XV144.   I wonder if in the 
near future you might consider phase locking their L.O.s to a 10 MHz 
OCXO.  I understand that there are some Beta units in the field that 
are locking the K3's TCXO to 10 MHz (when can I get one?).  It would 
also be great if you could do the same for your 2M xvrtrs, so that 
they could be synched to the same stable source.

Many of us VHF/UHF/Microwave weak signal and EME 
experimenters/operators, are now phase locking (via a 10 MHz source) 
our xvrtrs to those upper bands, most of which use a 2 M IF.  At 
present I don't believe that there are any other manufactures or 
vendors doing this yet, for 2 M xvrtrs.  It would really be a boon to 
have a self contained, ultra stable and accurate, 2M IF system the 
quality of a K3.
