Hi Domenico,

 

started looking only at 20 UT. Your signal is strong here, and timing and frequency are accurate. So it became an easy decode with Eb/N0=22.1 dB from only one symbol error.

Yes the longer code is indeed more computationally demanding. Fortunately such a strong signal usually decodes within the first two rounds (either 0° or 180° flat phase).

 

73 and good luck,

Markus
