AO-7 resets every time it enters/emerges from eclipse, the batteries have failed open circuit, and the spacecraft runs only off panels and only while in sunlight. It comes up in either mode A or mode B, although it has been favoring mode B lately by a wide margin. A good site to check for the current mode pattern is:
When AO-7 enters a period of no eclipses, the 24 hour mode change timer toggles between A and B just as it was designed to do 32+ years ago. The satellite is _entirely_ hardware driven, and much of it still works when the panels see sunlight, including command functions. The next period of no eclipses begins this fall.
Please enjoy AO-7, and remember to keep your uplinks into AO-7 at levels low enough that they don't "FM" or distort the passband. There are several regular users on the satellite, so making QSOs is usually possible on most passes.

AO-7 as far as I know is locked into one mode and it comes on and off depending on the batteries. -Steve VA3SAX
