I'm glad you got that!   I've updated the list of results at

Sometimes normalisation helps, not always, sometimes it makes it
worse!  Certainly with a transmission that straddles day and night
conditions it is worth a try.

The -a value is the number of symbols width of the sliding
normalisation window.  With 100 second symbols you might
do a little better with say, -a 20

The carrier Eb/N0 is a lot lower than the estimate from BER.
Sometimes that's because there's some interference in the input
band and that adds to the background noise measurement.
