Auto Tuning off Oct 27-28, 2005

The autotuning, or dither, in the Sigma Tau maser produces sidebands at +/-28 Hz, which can be a problem for some observers. During a Lunar radar run Oct 26-27, 2005, the autotuning was turned off. This resulted in the frequency changing by ΔT/T = 3.22x10^-11.

The offset of the site 1 pps vs GPS is plotted here. The samples are every two minutes.

From "A" to "B", the clock offset runs from about -1200 to -4300 ns.
