Here's the full set of overnight transmissions:

 5th/6th   Eb/N0 -2.2 dB  phase -148.4 deg
 6th/7th   Eb/N0 +0.9 dB  phase -165.4 deg
 7th/8th   Eb/N0 -0.5 dB  phase -163.1 deg
 8th/9th   Eb/N0 -4.4 dB  phase -150.2 deg
 9th/10th  Eb/N0 -2.9 dB  phase -146.5 deg
 10th/11th Eb/N0 -3.1 dB  phase -158.8 deg
 11th/12th Eb/N0 -3.5 dB  phase -157.1 deg

 Stacked: Eb/N0 6.3 dB  phase -156.6 deg

Looks like we were lucky with the signal 6/7th.
