ISTR that you started it with a short time constant to get locked, and once you had lock you would increase the time constant in a few steps to a final value of (say) 1000s or so.

I will have a look at the docs. The machine is running well, particularly the OCXO is performing very good when free running (without GPS signal). It is stable and its ADEV looks good (2E-10 at 10s). Not so the overall ADEV (when GPS locked) (1E-5 at 10s). It seems to not having the right filter time constant what had to be much longer. As I understand the documents, the filter constant can be programmed and I will experiment whith that this afternoon.
