[time-nuts] Question about Symmetricom ET6000

[AC0XU (Jim)]

Time-Nuts-

I have a Symmetricom ET6000 which reports acquisition but no date/time or oscillator lock. The front panel says "mode D7", which I don't find mentioned in the ET6000 Users Guide or the Encore Users Guide.

Anyone know what "mode D7" means?

I understand that this unit has a TCXO and is not known for great stability, but apparently the firmware can be swapped out for an OCXO version. Does anyone have access to that firmware?

Thanks-

Jim
