Thanks for the comments.  "FOX-1A Computer RT Battery 12c "FAIL " is an
issue, but we saw it on the ground when testing the Flight Model.  So it it
a known problem and is only an issue with the measurement system, not the
actual hardware.  We won't have that issue on Fox-1Cliff and Fox-1D, so you
will get to see much more Battery telemetry for them.  In fact you can see
the difference by looking at the Spacecraft Health tabs for 1Cliff and 1D.
Note all the extra telemetry values.  These are the ones that are not
making it through the Battery I2C bus on Fox-1A.

For unattended operation, you can leave Track Doppler and Find Signal set,
but note they are experimental.  Please report back on how well they work.
If you have the option to receive from an SDR or a real radio with SatPC32
setting the frequency, then you can do that too.
