I appreciate the reports about S band. As you might have surmised, in 
this mode we are running without live telemetry. This configuration 
comes pretty close to using the maximum available power. If the voltage 
drops below a certain set point, the S band transmitter will trip off, 
and the satellite internals will heat up significantly with the reduced 
load. We want to avoid this if at all possible. Having daily reports 
from around the globe that the S transmitter is still on is a valuable 
asset to the command team. I just thought a little explanation was in 
order. Thanks to all that have sent reports to me or the -bb.
