This has peaked my interest in this old bird. Is there a schedule someplace that I can view to know when it will be in mode "A"?

No. When the satellite powers up after losing power in eclipse, it comes up by default in Mode B and pretty much enters Mode A randomly, usually when someone transmits with too much power, causing a voltage drop that causes the satellite to switch modes.
When the satellite is in constant sunlight, it does switch between Mode A and Mode B every 24 hours, but there are never very many users of Mode A.
Between October and December of this year, this will be the case and Mode A should be available every other day, but after that, AO-7 will not be in constant sunlight for many years.

And as Drew mentioned the other day, if it gets hammered too hard with excessive uplink power, it will either flip modes, or reset.
I'm taking my Buddipole and a length of coax for a 10 Meter antenna this weekend, "Just In Case"!
