Hi everyone,

I'm a newbie here at time-nuts, but I have read the postings for a while.

I just got a Datum 9390-55184, this is a older version (88 mm height) and a 1 MHz oscillator, no oscillator output, but timecode.  After an adjustment of the oscillatorfrequency the gps receiver is tracking satellites and displays and rather low frequency error around 10-20e-12. The locked led doesn't turn on, but otherwise everything seems to work (could also be an bad led...).
Next thing is to hook a computer to get some status. 

Are there any documentation of this device among the time-nuts members?

Some functions are easy to understand, but not everything...

I notised that the gps receiver stopped tracking if I set the oscillatorfrequency to much off, so it seems to be used by the receiver.

Thanks in advance!

Best Regards,

Mikael Alexandersson, Sweden
