Hi Based on Time Nuts data - The OCXO's in the TBolt's have indeed gotten better over the years. The early "Piezo" labeled parts did not do as well as the later "Trimble" labeled parts. With the Trimble labeled parts, roughly pre-2002 is a break point for performance.

I believe the original TBolt (fancy red case) did have an OCXO but it wasn't particularly high quality. Perhaps Bob can shed light on this. 99% of TBolt's found on the surplus market today, and all the ones in the TAPR deal, have a surprisingly good OCXO's. These were customer specials as best we can determine, and never described on Trimble's web page. They are in the plain brushed golden color aluminum case. The Thunderbolt E is a relatively new product (fancy blue case, ROHS-compliant) and isn't yet on the surplus market. /tvb _______________________________________________ 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. _______________________________________________ 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.
