The link on EEVblog is http://www.eevblog.com/forum/projects/a-look-at-my-symmetricom-gpsdo-(ocxo-furuno-receiver)/ the Symmetricom and the Trimble you referenced are almost identical in operation. Issue is receiving one that works, a bit hit and miss. Apparently the next version of Lady heather will be able to monitor it. With the Symmetricom you are somewhat limited to what settings you can apply to tweak it, at least as to what limited documentation is available to do so. If you have a decent antenna and a good view of the sky you should be fine.
NOTE be careful with the voltages that may be quoted. The Trimble's are NOT 12v. search Time-Nuts for more info -=Bryan=- ________________________________ From: time-nuts <[email protected]> on behalf of Bob Camp <[email protected]> Sent: October 23, 2016 6:56 AM To: Discussion of precise time and frequency measurement Subject: Re: [time-nuts] Has anybody checked this? GPSDO in kit Hi There is a *long* list of information on that unit over on EEVBlog. Bottom line is that if you get a good one (you may not) it is a *much* better solution than the other one you are looking at.
