Hi gang!
There is no battery left in AO-7. All the current is generated by solar
panels and the only "power buffer" is the capacitors in the regulator board.
This may cause the voltage drop that also affects to output power and
shifts oscillators. The solar panels are quite old too...

Tim,
As usual, very informative information on "The Grand Land", AO-7! Tim you
remind me of only a few professional athletes who respect the game, know
it's history and play it "correctly". Well, AO-7 is like an aging athlete,
don't put to much pressure on her or ask her to do to much. I'm
disappointed in a few operators who don't understand or care what too much
power can do to a linear satellites passband, if this was HF everybody would
be doing it, thank you for teaching all of us Tim.
