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.
