Then you have misunderstood how little you actually need. This is the "front-end" I ran most of my VLF experiments with: http://phk.freebsd.dk/loran-c/Antenna/ A single AD797 and via 10m of coax directly into an ADC. Modern capacitor-based ADCs work fine with even very small signals, many can be run with sub-volt VREF and still be perfectly happy. There really isn't anything to it... The only reason I'm not active in VLF any more is that I have to choose between VLF reception or my robotic lawn-mowers, and with 5000m² of lawn, that is not even a close call. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 [email protected] | 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 -- [email protected] To unsubscribe, go to http://lists.febo.com/mailman/listinfo/time-nuts_lists.febo.com and follow the instructions there.
