Bob, you of all people must be able to answer this: OCXO's have specified temperature ranges for instance -40...+70°C for the heavy duty stuff. But I cant imagine the ovens used are so perfect that they have the same regulation performance at all temperatures. I can choose the exterior temperature, which I should prefer ? Disregard aging of electronics and materials, we all know that stuff, what I'm interested in is at which exterior temperature OCXO ovens work best ? -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 p...@freebsd.org | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
