I have to agree with John...significant increase in the polarity switching noticed both on the US west coast pass last night (02-Dec-09 0158) and this morning (03-Dec-09 1417). This morning's pass required a lot of switching...some of it back-to-back (10 seconds between switching). Also, it took a long time to acquire the bird and I lost it early as well.
We are still sifting through the telemetry, but as Tom suggested in his email, the satellite is precessing (wobbling) quite severely. This will calm down as the hysteresis rods do their job. Initial reports from Australia and New Zealand indicate stronger signals, and about the same from South Africa. There are some peculiar things about the magnetic field near South Africa, so that doesn't surprise me too much, but is worth digging into once we get the telemetry down.
