Hi Dick, Please contact directly with F5CAU about the PCB and PIC code..... also there is a VE2ZAZ based GPSDO......please see this link.....

Designs from that era need to be upgraded to eally get them to be all they can be with SA turned off.

I think all three designs would fall short for most on the list, but for me it >s hard to tell the difference. Did you have another design in mind ? Stanley <snip> Now I am reading Time-nuts history and I see that there is no consensus on which of the popular/published GPSDO configurations is the best return on effort and expense. That is rather disappointing. Any comments on that before I just flip a coin? <snip> _______________________________________________ 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. ______________________________________________ ime-nuts mailing list -- [email protected] o unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts nd follow the instructions there. _______________________________________________ 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. ______________________________________________ ime-nuts mailing list -- [email protected] o unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts nd follow the instructions there. _______________________________________________ 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.
