I’ve had an intermittent problem with my ET6000/9390-6000 GPSDO where the reported error (the FRQ: display on the LCD) initially is OK (low E-12’s) and then creeps up to the limit (~500), and the tracking and locked LEDs go out. I’ve spent some time troubleshooting this and it seems confirmed that the GPS module has finally gone south. I’m asking if anyone has a similar module tucked away somewhere. The module is basically a Trimble SveeSix-CM3 and is based on the 25040 board. It’s labeled 26889-81 so is a variant of the standard TSIP part. Can anyone help with a replacement? Exact replacement would be ideal of course, but even a standard CM3 would be useful - I’ve done other ‘conversions’ before. Thanks Paul

If your friends don’t have a CM3 spare, there is one on eBay item 141712522709. It might be worth pulling the GPS part and testing it stand alone as there have been numerous week number roll over problems surfacing. If that is the case for yours then a replacement gets you nowhere. > Le 16 janv. 2017 à 07:32, ziggy9+time-nuts@pumpkinbrook.com a écrit : > > I’ve had an intermittent problem with my ET6000/9390-6000 GPSDO where the reported error (the FRQ: display on the LCD) initially is OK (low E-12’s) and then creeps up to the limit (~500), and the tracking and locked LEDs go out.

I did see that one, but I am hoping I can procure something that isn't from an overseas surplus scrapper. If I can't find anything else, then I guess it's my only choice. Unfortunately, the Heol folks don't have anything to offer here either. It's not a WNRO problem, as the week and date are correct. Even if not, that doesn't affect the GPSDO, only the timecode generation. Thanks for replying and the eBay pointer.
