Decoded with Eb/N0 =3D +2.6 dB, rank 1, BER 41.6%Reference phase -120,-120,-150,-150.
S/N -29= .86 dB in 1Hz.

Phase was -50.9 deg, previo= us nights were +19.1 and +35.7 degrees,
has something chang= ed the phase of the transmission?

At Biele= feld, -9.0 dB;

At Cumiana, -8.4 dB;
(3 nights stacked =3D -4.2 dB, less than 2 nights stacked,
phase did not repeat)

At Warsa= w, -13.8 dB;

Good luck with the 2 char mes= sage, maybe that will decode
at Cumiana.
