 Night 2nd/3rd: -24.26 dB in 1Hz,  phase  34.9 deg
 Day 3rd:       -24.31 dB in 1Hz,  phase 100.1 deg
 Night 3rd/4th: -32.16 dB in 1Hz,  phase  24.3 deg

Got a strong decode:

 carrier Eb/N0: 7.9 dB
 carrier S/N:  -31.16 dB in 1Hz, -65.14 dB in 2.5kHz
 phase: -157.3

Not sure why the phase is completely different to that of the
recent carrier measurements.
