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,
