>Luis, Hard to believe the Cs tuned Rb osc is not really at 10,000,000.??? Hz.

>From the description it never stops going up
(or down) so only 3 possibilities:

-the loop is not closed
-Rb is off frequency
-the 1pps is off freq.

  Hi, 
  I have been thinking this configuration over a little more (perhaps better late than never). 
  The frequency tuning range of the FRS Rb osc is only +/- 1E-9 min, over a 17 V range, 
  and has a 10 sec Tau of 3E-11.

  With this in mind how much steering is going to available to "lock" to a GPS (even an M12+) ?

  Any opinions ?

  >From your description it really looks that
  what you think it is the exact 10.000 it is not.

  Luis, Hard to believe the Cs tuned Rb osc is not really at 10,000,000.??? Hz.
