Hello,
There is a bug in the FM demod. Unbelievably (almost), I reported a bug in the same line a couple of years ago. At that time I also goofed (should have not retyped it). The equation is STILL wrong!
Sdot = d_scl * (-S0+d_8*S1-d_8*S2+S4);
Should be
Sdot = d_scl * (-S0+d_8*S1-d_8*S3+S4);
It is crazy that the basic FM demo works at all.
