[time-nuts] Thunderbolt reception problems

I'd sure guess a good disciplined rubidium should win over the Tbolt.
But if the Tbolt does not come in a close second, 
Give me another chance to change some of your other default setting.


 It would be interesting to see what the ADEV plot looks like using Ulrich's plotter program. .
OR email me your raw data file.

Hi Warren,

checking the PRS-10 against a FireFly-IIA now, and later this month against a Fury GPSDO.

That should clarify which unit has the best performance in my setup, including temperature cycling, the antenna/splitter challenge, etc.. I suspect the PRS-10 with an 8+ hour TC is going to be the best.

BTW: the test data is very close to 10 samples/s.

bye,

  could be because the TC of the PSR10 is set to the wrong TC, It should be around 10K+  sec.

  Something to be aware of, but does not really change how or what you are doing here. 
  Because you are using the same reference for both units (the GPS system), 
  very low freq noise in the reference (GPS) which is much slower than either's TC will not be seen.
