I have played with it another way: I set the receiver to 7500 and fed it a 10MHz that was detuned 1 part in 7500 (actually generated by DDS but you get the idea). I did think about generating the 4-digit timing with a PIC16 instead, but never got around to it. -- 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] https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
