Decoded with Eb/N0 +5.2 dB, constant reference phase.

Decode has md5 hash: d2ddea18f00665ce8623e36bd4e3c7c5

carrier S/N: 15.72 dB in 29.8 uHz,
            -29.54 dB in 1Hz,
            -63.52 dB in 2.5kHz;

No better decode after full phase search in 30 and 15 degree
steps.

Best decode with a +9.3 uHz offset was 4.1 dB with
-120,-135,-135,-150 phase pattern.

With -9.3 uHz offset it was 5.1 dB with -15,0,0,15 degrees.

Best offset was S/N 15.78 dB at -2.3 uHz, constant reference.
