[time-nuts] GPSDO choices

Paul,

I don't want to speak too soon or appear to be tooting the HPSDR horn - but
the Khronos board (Khronos is the name of the board that I mentioned in the
previous e-mail) has that.

I didn't realize the issue here was the BNC connector and your dislike of
the MMCX style connector that is pretty much a standard for passive GPS
antennas (I guess any GPS antenna).  The Khronos connector for the LC_XO
option for the antenna is a standard footprint and you can put what you
want on that.  What type of connector do you prefer for the GPS antenna?

Pasternack, Samtec, Mini-Circuits, Digi-Key are all your friends in these
situations - but if you prefer not to solder or to DIY, then it could be
difficult to find everything you like in one package unless you custom
order it or have a friend that can put it together for you.  I am a
customer of Metcal - I have a lot of their top-of-the-line equipment, so
soldering/rework to me is almost a way of life.

Best Regards,
John Westmoreland
