[time-nuts] The low budget UT+ newbie time-nut project: Frequency Reference

I think the lowest cost GPSDO frequency reference has to be one made
from these parts. You can get up and running for under $50.
1) the UT+
2) a patch antenna
2) the Lars Walenius Arduino based controller, using the $3 version of
the Arduino
3) An eBay OCXO for about $20. (this is the most expensive part)
I built the above and at every decision point did what was both
simplest and lowest cost. I just wanted to see what would happen. I
ran it for a few months. I kept the output of this and the output
from a Thunderbolt on each channel of my dual channel scope. Visually
they kept in phase. One would drift right of left then be corrected.
I could not see it drift, I'd have to come back and check now and
then. Yes I know not a good characterization but in keeping with
the "simplest thing that can still work" idea.
