Depends on what you want. Stability or accuracy? Bench or portable? The TBolt or another GPSDO will certainly be accurate. Probably fairly stable as well. However, if you need portability, the OCXO is the only way to go. You will have to look at the stability measurements of the OCXO versus the GPSDO to choose that one.

Thanks to the list for the answers - but: It seems like everybody is telling me "go for the cheaper, add the OCXO lateron if you need it" - but that's not what I'm after. What I'd really like to do is to make up my mind based on educated opinions on this list whether the built-in OXCO option offers any advantage at all compared to standard clock + good external reference. - Wolfgang, DL1SKY _______________________________________________ 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.
