08/20/2003: "5065A longer term plots"

While away for a few days vacation, I kept the HP5065A via Loran-C data collection running, and just analyzed the results. I have about 3.5 days of data between phase rollovers (ie, where the 1 microsecond recorder output hits the rail and wraps to the other end.

The frequency offset is currently -3.49x10^-12 (with the C-field set at 1.82).

Here is the raw phase plot.
Here is the phase plot with offset removed. You can see that there is a diurnal effect; I haven't determined yet what is causing this.

Here is the Allen Variance.
