Anyone else try to send packets via FASTRAC 1 on the most recent two
passes late evening over North America?  I only received the CW beacon
and one burst of telemetry on each of the two passes over East Texas.
I did notice on the first pass that my Keplerian elements were off by
a little bit but had corrected it in time for the second pass around
05:15 UTC 3-12-2011.  I tried both 1200 and 9600 packet to no avail.

Shortly after I read the announcement on Thursday that FAST1 (AKA Sara Lilly)
was going to be put into the Digipeat mode, I plugged it into Satpc32 and saw
where I had a pass in 10 minutes for about 10 minutes. Here is what I was able
to get through and copy with 1200 baud packet on that December 1 pass around 14:50 UTC.
145.825 up and 437.345 down +- Doppler...

That's all she wrote... .  Haven't been able to Digi through it since. Only
a few telemetry frames have been copied to date. Maybe the battery was
depleted enough to cause the reset they were looking for.. To bad we couldn't 
swap AO-51 batteries with them...
