All decoded with no problem. So far we have

16:00 Eb/N0 = +10.4 dB -24.2 deg abs phase
19:30 Eb/N0 = +8.8 dB -7.2 deg abs phase
23:00 Eb/N0 = +11.0 dB -1.8 deg abs phase
02:30 Eb/N0 = +10.8 dB -10.2 deg abs phase
06:00 Eb/N0 = +4.0 dB +7.2 deg abs phase, ref 0 0 -30 -30

All decoded with constant phase reference except for 06:00 and the
absolute phase doesn't change much for the whole transmission.

The 06:00 shows the disruptive effect of the terminator passage.
