I'm still having no luck with mine.  When I power on, the LEDs cycle, the Fault light is on and the No GPS and Standby lights flash.  When I connect my GPS antenna, the No GPS light stops flashing and stays on.  After several minutes only the Standby light is on.

When I connect both the Ref1 and Ref0 together with the interface cable, the Fault lights on both units are illuminated.

Do you see the same?   I don't know what to infer from the Fault light since there is no supplemental data to work from.

My system arrived today in original unopened boxes.  Hooked up 24 volts and a gps antenna and it locked in about an hour and 10 MHZ output as compared with thunderbolt GPS seems to be working just great.  No trace movement on scope using thunderbolt as trigger and looking at Lucent 10 MHZ output.
Strange output pulse!  Looking forward to 10 MHZ sine wave output mod that the gurus on the list will discover.

Wonder what these units cost new when they were built?
