since the plot has a step jump, seems only a few tens mC, and then it comes slowly back to the "normal" track, I'd rule out at least an external temperature change: the thunderbolt can easily detect an hand in its proximity even for a few seconds, but I don't remember ever seen a step change. Could be a firmware/sensor/communication error, but I'm not able to explain why it comes back to normal slowly (but I'm sure there's a firmware reason for that).
Frank,
thanks. I can obviously rule out a hand or a body in proximity of the GPSDO, as when that happened I was alone in the house and moreover the door was locked. I would tend to consider it some sort of glitch either in the firmware or in the temperature sensor. I would be curious to know if somebody else has ever observed in his Thunderbolt a similar phenomenon. 73 Alberto I2PHD _______________________________________________ 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.
