In the old code of GNU Radio in the folder /usr/local/share/gnuradio/examples/usrp$ you will find two examples
usrp_wfm_rcv_pll.py & usrp_wfm_rcv..py ..
The important difference between
these two is that the former uses a PLL for demodulation while the later uses an arctan demodulator for FM demodulation :)
