So ... how come I could hear myself when AO-7 was in darkness?. As can be imagined, I will keep tabs on this tomorrow morning.
Sensible explanations please written on the back of a clean $100 bill wrapped round a wallbrick and chucked through my window - or - an e-mail to la2qaa@amsat.org at a pinch, will suffice

My explanation
The various tracker show up the GROUND track the point where the satellite is passing over a point on earth at ground level. But if the sat is at 800KM he can be illuminated by the sun. It is the same phenomenon when you see ISS passing over you you are in complete darkness but you can see the sun reflection until iss goes out the solar range illumination point.
I often hear AO-7 when he's in the darken part of my tracker map but at his elevation he's starting to pick up some light and it takes not too much light.
