Daily Eb/N0: 23rd -6.2 dB 24th -16.8 dB 25th -9.2 dB 26th -10.3 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 'PEACE' at Eb/N0 = -0.8 dB, BER 41.9% constant reference phase. I used 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 full 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. -- Paul Nicholson --
