Hi Paul,

Thant's exciting! You will get the result, i know it :-) Maybe just 0.1 dB missing? Running the decoder in 15 deg steps could help as well, you know.
I could not sleep when beeing so close to the result :-)

73, Stefan

Progress: so far, a partial decode

 'DK7FC4R,3ZSB35X'

at Eb/N0 = -0.4 dB with a phase pattern of 120 90 90 60.

I am branching out from there with some small frequency
shifts and beam shifts.    Just need to squeeze another
fraction of a dB out of it.  Will leave the decoder
running overnight with a range of settings.
