Re: [Discuss-gnuradio] carrier-tracking on FSK

[George Barrinuevo]

I found it.  This is what I found on FM/FSK
carrier-tracking:

        audio_rate = 20000;    
        alpha = 5 * 0.25 * math.pi / (audio_rate);
        beta = alpha * alpha / 4.0
        max_freq = -2.0*math.pi*18970/audio_rate;
        min_freq = -2.0*math.pi*19030/audio_rate;

        stereo_carrier_pll_recovery =
gr.pll_carriertracking_cc(alpha,beta,max_freq,min_freq);
       
stereo_carrier_pll_recovery.squelch_enable(False);


There is also gr_pll_refout_cc and gr_pll_freqdet_cf.

Thanks,
