Hello , last week i worked with osmo-gmr projest ,but still have some questions: 1. I need some more info about S band GMR - what sat is this , az / el , what trafic etc. 2. About gmr1 ambe decode - i tried about dozens of .dat files from gmr1 rx live , some give me ! codec errors , some not , but all .wav audio files are scrambled ,speesh is not recognized at all .. is there some clear traffic at all, or all is A5/2 coded ? 3. If all is scrambled where i may find offline tables / H n matrix/,any source that may generate them ? And if i have tables how they will be integrated with existing osmo-gmr ? I see gmr1_gen_mat that generates G/g matrix .. some more info about that .. .G and .g files seems so small .. Thanks in advance !
