ARRISat-1 continues to function although the
signal from orbit to orbit is quite different. On
the previous pass at 2135z 30 Oct, I could barely
hear my downlink.  I was hearing W8ZCF and he heard
at least part of my call.  On the next pass at 2309z,
the transponder was strong and I was able to hear my
downlink until the bird went silent at 2313z just before
it eclipsed. A good contact was made with K9OIM.  I guess
it all depends on the angle with respect to the stubby
uhf antenna.  ARRISat-1 does go off even when it is in
good sunlight.  Then when it looks like it is just barely
getting enough sun, the bird stays on and the signal is
strong.  You just never know what it is going to do.
