Yes, but they do have a good reason for it here: They want the C-field pot to be "calibrated" in frequency so they need the resulting voltage to follow the quadratic C-field sensitivity decently well. I still havn't figured out what component is responsible for the huge tempco, but it is not the C-field pot. There's a few PPM there but not that many. -- 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.
