AO-16 continues to spontaneously shut off. We suspect it is a watchdog timer that is malfunctioning, and that it is temperature related. These resets began shortly after the satellite re-entered periods of eclipses after a long period of full sun. Mark Hammond, N8MH, and I have, at various times, recommanded the bird on. It will stay on for anywhere from just a few seconds to a few minutes. We've even experimented with doing this automatically, with not much success.

The current plan is to wait a little bit until the eclipses start getting shorter, the overall temperature of the satellite rises some, and see if the frequency of the resets goes down enough to make some sort of day-to-day operation feasible again.
