Note that the existing (non-beta) version of LH has some pretty debatable serial-port code in it. You may just be seeing data corruption. If it happens with the 3.0 beta version, it's may be worth investigating. > LH often indicates that the blue PPS ADEV and the > red OSC ADEV are both in the high E-13 zone for several > hours and then invariably, both will drop back to the > mid E-12 zone and sometimes stay there for many hours. Nature of the beast, really.

The auto-scaling has undergone some improvements, too... if you're not running the beta, give that a try. -- john, KE5FX _______________________________________________ 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.
