The power management software is still a work in progress.  We have done 
testing on it, but we have more testing and tweeking to do.

I have rarely changed the power level for TXB over the last few weeks.  I 
have been compensating for longer eclipse times by lowering the TXA 
(digital) power level.
The signal change was due to satellite spin and wobble, we have been 
studying this also.

I will be taking about the software changes at the AMSAT Forum at Dayton 
this year.
