It happened here too. It is reporting having the 3.0 firmware. Right at the time Tom said. Fortunately I am simply using this unit for PPS and nothing else.

Some Trimble Thunderbolt TBoltmon.exe screen shots attached: GPS WN 1959 TOW 604799 (July 29, 2017 23:59:41) advanced to GPS WN 936 TOW 0 (December 13, 1997) instead of GPS WN 1960 TOW 0 (July 29, 2017 23:59:42). 1960 - 936 is 1024 weeks, as advertised for this version of the TBolt GPSDO. Note this happened at 23:59:42 UTC as expected (that's GPS midnight - 18 UTC leap seconds). I did not expect the reported 2.75 us 1PPS phase change and will look into that. /tvb _______________________________________________ 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.
