Fellow Time-nuts, I've left my HP Z3801A unattended but running for quite some time. It now seems to have started making more sense. When I checked it a few days ago, it was still a bit high in Predicted holdover uncertainty, but right now it clocks in at 900 ns/initial 24 hrs. That's about 1E-11 in frequency error. Pretty impressive. Now, this is only one sample, so I expect it to be worse for awhile (while it dropped to 800 ns). Ah well. Let's see if it sticks. If so, I may have a good unit after all, or maybe it is just a better environment for it now, who knows.
I am wondering whatever fun I could make of the builtin forth-interprenter, but right now I am considering writing myself a logging application (this is not the time to again give me tons of links to Windows-apps - no use!). For the clock-status I'm considering logging the TI-difference and holdover uncertainty. For GPS status I'm considering logging the tracked signal-strengths at their different Azimuth and Elevation values. The actual satelite tracks themselfs isn't as interesting as their position in the sky relative to my antenna and what the signal strength map I get from that.
