[amsat-bb] huskysat-1

[Burns Fisher]

Ok, I think we get what is happening.  This is showing it switching modes.
Chances are UW changed its mode to get more science data when it went over
them.  That timed out while you were listening and when it switches mode,
the buffers are cleared out and we start with a little sync bit pattern.
What is curious is that the mode shows a change in the Whole Orbit Data,
but it is not being displayed in the realtime data.

Thanks to everyone for bringing this up!

73,
