Must have been some sort of interference this morning, but led on module had been pulsing at 1s each time I looked. Radioclkd2 -v -d had shown it was seeing MSF (rather than WWVB or DCF) but I hadn't left that running long enough to see it had actually worked out correct time. Tonight I gave it another couple or tries with "ntpd -q" reset +0.150s within 300s then used date to give a bigger initial offset reset +66.9s within 330s then started ntpd and was in sync within 260s That's good enough for me. The usb connection rules out PPS mode and seems to limit to +/-10ms. cheers David _______________________________________________ questions mailing list questions@lists.ntp.org https://lists.ntp.org/mailman/listinfo/questions
