Decoded after stacking three of the daily transmissions.

Eb/N0 = -0.7dB BER 34.7% at rank 71540 with constant
reference phase.

S/N (three days combined) 20.00 dB in 33.8 uHz.

Each day:

 10th -5.8 dB  phase 24.5   -63.9dB in 2500Hz
 11th -5.3 dB  phase 22.8   -63.5dB in 2500Hz
 12th -4.9 dB  phase 16.8   -63.0dB in 2500Hz
