Ich habe ein kleines Weihnachtsgeschenk für Stefan!

The 75 character message received at 6470 Hz:

"HABE DEN MUT DICH DEINES EIGENEN VERSTANDES ZU BEDIENEN
- IMMANUEL KANT -"

by coherent summing of 7 daily transmissions.

Eb/N0 = -0.2 dB, BER 32.44%, constant reference phase.

List decoding rank: 1987053.

S/N: 26.14 dB in 36.9 uHz, -52.2dB in 2.5kHz.

Day Phase Eb/N0
2016-12-18 41.2 -5.5
2016-12-19 47.2 -10.1
2016-12-20 38.0 -8.2
