[Elecraft] K3S XREF GPSDO recommendation needed

[Edward R Cole]

I do not use a GPSDO for 10-MHz reference source.  Instead I bought a 
Russian surplus OCXO from e-bay for $40:
http://www.kl7uw.com/K3EXREF.htm  was my beta-tester report
http://www.kl7uw.com/Rubidium.htm more info on OCXO install.  I 
stopped using a "wall-wart" for 12v supply after discovering excess 
ripple from the "wart".  Now I simply use my station Astron 50 which runs 24/7.

For GPS time I use a little GPS dongle (plugs into computer USB 
jack).  Model BU-363 found on e-bay for about $15.  I run BktTime 
(IZ2BKT) sw to control computer time (previously used 
Dimension-4).  This keeps my computer time accurate for running JT65.
