Even the 50MHz and 200MHz multiplier boards could be done a lot better nowadays, say with Crystal based VCXO's. I always like opportunities like this that give better performance in an evening or two worth of experimenting. bye, Said ************************************** See what's free at http://www.aol.com. _______________________________________________ time-nuts mailing list [email protected] https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
