The signal is definitely frequency modulated, but it doesn't appear to be by data. Plotting the unwrap(diff(unwrap(arg(s))) shows a repetitive structure of 10 ms (500 samples) width, as if something is stepping the frequency up or down at 100 Hz in a random walk. -- Johnathan Corgan, Corgan Labs SDR Training and Development Services http://corganlabs.com
