Hello, I've finally figures out the demodulation of my strange FFSK signal I've asked about in my last Email "FFSK/MSK Demodulation in Gnuradio". I've used the attached flowgraph and the demodulation works fine now. Apperantly it had a bitrate of 2400, since the wave with Complex to Mag works way better with the second Low-Pass Filter adjusted to 2400.
But now I wanted to send a similar signal as my next step. But I have no idea what kind of modulation is used here, even though I was able to demodulate it. Does anyone has seen something like this before? If I use Quadrature Demod -> Hilbert -> Complex to Mag would it be possible to reverse this somehow? Can I use AM Modulator -> GFSK Modulator or something similar? Greetings, Michael Kramer
