I'm trying to identify the OCXO in my Tbolt; hoping that it's one of the newer parts, as in the TAPR units. Is there a P/N, or other obvious means of identifying the newer, low noise OCXOs? ----------------- Hi Pete If you look at John Miles' web page where he first raised this issue..... _http://www.thegleam.com/ke5fx/tbolt.htm_ (http://www.thegleam.com/ke5fx/tbolt.htm) you will see that the oscillator he reported as being "lower grade" was made by "Piezo". He also comments that this was an earlier unit and that higher quality OCXOs were already present in Thunderbolts with a 2002 manufacturing date. Any Thunderbolts I've seen have been dated 2002 or later and all, including two TAPR units, have contained an oscillator that is labelled as a Trimble 37265. Other markings on the oscillator case, other than frequency, are subject to variation so are presumably just batch and date codes. Based on this I think it's likely that any post 2002 Thunderbolt with the Trimble oscillator, not just those from TAPR, will be the higher spec unit. regards Nigel GM8PZR _______________________________________________ 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.
