If such conditions detected, I avoid problem by changing the counter clock. 
But it does not solve the effects at "about OCXO" * N or "about OCXO" / M. 
It is related to HW and I can probably control it only partially. I will try 
to improve clock and reference isolation in the "normal" HW and of cause I 
will thoroughly test such frequencies when that HW will be ready.

All the best!
