I would probably start out trying to get the thing to work, then optimize later. For instance, I would start with an off-eBay HP synthesizer, rather than fight with GHz frequency PCB layout. >No doubt, I will have a lot of fun with the project. Ohh, absolutely. Have you visited the Science Museum in London ? They have the original Cesium beam frequency standard, spending a couple of hours with that would probably help you determine what/where the really hard bits are. Also, consider paying PTB a visit, they can probably be persuaded give your a tour of their designs. -- 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 -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
