Very nice, a good result at about 70% of capacity for
that carrier S/N.

The 54% bit error rate is false, indicating part of the
signal was missing, I guess there was some padding.  This
misleads the error calculation so that it comes up with
crazy Eb/N0 like -7.9 dB.   The 0.1dB calculated from the
carrier strength is almost correct.
