[time-nuts] Z3801 EFC error

[J. L. Trantham]

I think it uses a 10811 OCXO.  See if it is warm.  If not, perhaps the
'thermal fuse'?

Subject: [time-nuts] Z3801 EFC error

Hi,
My Z3801 just crapped out.  It seems that the DAC has ramped up to the
rails, 1048560, and I'm getting an EFC fault.  Any tips before I open the
unit and start poking around?  The oscillator is running and pretty close to
10MHz, I don't have any reference accurate enough to check it.  Any trends
here, is it the EFC in the oscillator or is it the DAC and following
amplifiers?

Thanks, Bob
