Sounds to me like you have two independent systems. I do not believe they can ever be “coherent”. Regards – Mike

I`ve just bought two GPSDO`s from China @ US$9-50 each [This is not an error!] They are stated as being new, and use a Trimball dual oven OCXO. I plan to run these in parallel [2 antennas, 2 feedlines, and 2 GPSDO`s] It`s been said that a man with two watches is never happy - unless, of course, they agree with each other ;-). Being identical the outputs should be coherent, unless one becomes faulty [one advantage of having two - any discrepancy and you know something must be wrong]], but is there some crafty way I can squeeze a little more "accuracy" out of two than if I only used one? TIA for your comments............................................Donald Brett Collie ZL4GX PS : I have no connection to the eBay seller. The US$9-50 seems to include a basic puck antenna, long downlead, and 4 interseries adaptors _______________________________________________ time-nuts mailing list -- <mailto:email@example.com> firstname.lastname@example.org To unsubscribe, go to <https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts> https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ time-nuts mailing list -- email@example.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
