The only thing I feel like beating them up about, is that appearantly they didn't consider the tempco of the R10||R11 pair (or maybe it is just R10 - not sure yet). Either way: If any of you have a non-amazing HP5065, Measure the A15CR5 voltage, multiply it by 76, and replace R10||R11 with something of that value and better than 5PPM tempco. -- 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.
