Re: [time-nuts] Ebay GPSDO for the price of shipping.
I always wandering about that "amoj" logo. Some time ago I got Oscilloquarz 8663 OCXO soldered to PCB with this logo. It has two sinus and two square outputs, basic power supply and trimmer to change the frequency. I could be wrong, but my impression is: the company creating useful items using some salvaged parts.

Barely. 4) I have too much of this stuff lying about and trying to fix one is of no value to me.

Re: [time-nuts] Ebay GPSDO for the price of shipping.
Hmm not to dissuade you from selling, but have you 'scoped the PPS on the RS-232/SMA outputs? My guess is you are seeing a very narrow pulse (uSecs) and need a pulse stretcher to actually do something like light a LED with it. Looks to be a nicely packaged unit.

Hi Last time I checked Trimble and uBlox were separate outfits. If a gizmo puts out uBlox messages, it’s tough to believe it’s a genuine Trimble device.
