[GCARC] ARLS002 ARISS Plans Do-Over of Slow-Scan TV Transmissions over February 15 - 17 Weekend

[Bruce Canino]

Well the transmitter is on and sending. I was able to decode images on the
two passes over the SJ area today. The next two passes don't get very high
so I am not holding out for them.  But the last two pass for today should
give some good images. The times for the chart are at 10 degrees which i
wasnt able to get a solid signal but a few seconds later it was good.  Also
the point where the signal drops out is a few seconds earlier. So check it
out chart in the last email and see if you can hear something over the next
three day
