I think it's (much?) more complicated than that.
The basic problem is that the 74LS90 is very very slow. W

The ADCMP602 is the version that comes in the MSOP package.

Hello Ulrich -
thank you very much for kind reply - this is a great suggestion. Would you
recommend simple 74xx74 flipflops driven by the original 10 MHz signal
delivered by the rubidium oscillator for resynching?
Thank you very much and have a great day - sincerely, Bernd. :-)

If the unit cannot lock up to GPS, it may be sending bad electronic
control voltage to the rubidium. I would look at the "lock" signal from
the rubidium to see if its on or off.
If its off, I would disconnect the EFC voltage from the GPS unit to the
FRK, and see if the rubidium locks (should h
