The "Trimble 57963-C" and "Symmetricom UCCM 089-03861-02" boards were previously discussed in August 2015. Over the past few weeks, the prices have decreased recently.
Sergiy in Kyiv, Ukraine reverse engineered some of the pin functions on the 50-pin connector of these OCXO boards. http://tipok.org.ua/node/53 These modules have no direct NMEA support, but have their own binary protocol and additional signals, available on the 50-pin connector. Should be useful for stable 10MHz and 1PPS signals. Notes on UCCM-P > http://abelian.org/vlf/tmp/notes-57963.txt -- EEVBlog also commented in these Trimble units (supposedly BG7TBL uses in some products). https://www.eevblog.com/forum/projects/trimble-65256-5v-10mhz-as-fitted-in-trimble-gpsdo-and-some-bg7tbl-output-level/ Andy Brown's Teardown Blog of the BG7TBL GPSDO http://andybrown.me.uk/2016/11/12/gpsdo-ebay/ YouTube Video https://m.youtube.com/watch?v=vH1q_Mh4luY greg w9gb Sent from iPad Air _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
