[time-nuts] Least costly 10 MHz reference solution

[Chris Albertson]

No question, You want a GPSDO.

Yes you can buy a Rb or a high-end OCXO but neither of these is
connected to any kind of standard and will need to be calibrated to be
of use.   The GPS serves as a "standard" and you need that before the
other options.

The next question is "which GPSDO?"   For most people that would be a
Thunderbolt but the prices are going up on those.  Then you will need
a good antenna installation.
