Hi Nigel, All I know is what's on the ebay listing. It's number 270851051022. There is a tiny RF connector on the top board of the 3 that are stacked inside the package that correlates with other modded boards I've seen online. It looks like people generally tap into that. Mine is supposed to have a 1PPS signal on pin-6, which I do not see. Also, there is a flashing LED inside that is not synced to 1PPS. I dunno whether that means it's not synced up yet, or that it is. Funny that it's just blinking, and not a 1PPS heartbeat.

It looks sort of like a uFL connector, but a bit bigger. I'd rather avoid hacking and soldering on this if I can. >> >>Bob - AE6RV >>_______________________________________________ >>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. > > _______________________________________________ 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.
