Either you need to characterize the exact behaviour of your filter and build the necessary compensation for its phase/frequency behaviour into your receiver, or you need a very flat filter (both freq+phase) in order to reliably recognize the proper zero-crossing to track. The more you disturb a Loran-C pulse, the more it just looks like a bit of a sine-function, and the harder it is to lock on the right zero-crossing. -- 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 https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
