Success!

Daily Eb/N0= :

23rd -6.2 dB
24th -16.8 dB
25th -9.2 dB
26th -1= 0.3 dB
27th -9.8 dB
28th -15.8 dB
29th -8.0 dB
30th = -4.9 dB
31st -10.2 dB

Leaving out 24th and 28th, I decode 'PEAC= E' at Eb/N0 =3D -0.8 dB,
BER 41.9% constant reference phase.

I us= ed a 'known phase' decode for this, using the phase measured
from your 2= day carrier.

It does not decode with a uniform phase search or a fu= ll phase
search. (the extra gain of the known phase decode is about 0.25= dB).

Ok, you see why my 0.13 dB rx mystery is important to solve!We cannot afford to discard even 0.1 dB with these experiments.
