You should do a test where you warm the rod+windings in your hand, I found the center frequency would drift significantly with even minor temperature changes. It would of course not be unreasonable to temperature compensate a ferrite rod antenna, but I have been wondering if it would be possible to build a SDR receiver for 60kHz (or 77.5kHz) where the CPU autotunes the high-Q antenna based on the detected signal, but have not gotten the necessary round tuit. -- 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.
