I've been happy with these: https://www.ebay.com/itm/10Mhz-GPSDO-OSCILLOQUARTZ-OSA-OEM-GPS-GPSDO-10MHz-1PPS-STAR-GPS-Clock/262861459973?hash=item3d33c39205%3Ag%3AsbYAAOSwh2xYAjrp&_sacat=0&_nkw=oscilloquartz+gpsdo&_from=R40&rt=nc&_trksid=m570.l1313
They are not nearly as tweakable as the Thunderbolt, but the GPSDO inside is made by a company that seems to know what they are doing. The 8663 DOCXO used in the ATDC version is thei highest spec'd version. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to http://lists.febo.com/mailman/listinfo/time-nuts_lists.febo.com and follow the instructions there.
