Hope this is not already answered, did a search for ‘modulation’ -
A frequent issue I hit when manually tracking and decoding is, what is the modulation for this one, SSB or FM??
Anyone know a handy list? Like this one has a few explicit hints Satellites and Frequencies and gr-satellites github used to have a hint but no longer. But like I want to follow 43793 CSIM-FD using 9600 GFSK and always end up in trial and error mode because I cannot find the radio modulation and haven’t compiled a private list of what works 
I’m guessing USB with -9.6k offset and got a really strong signal but nothing decoded, flipped to FM centered and still nothing.
