Look into using the pfb_channelizer_ccf block (it is not in gnuradio
companion, yet). Make the USRP capture wide enough to receive multiple
channels and pass this to the channelizer with the appropriate
settings. For N channels, you get N outputs of the channelizer. Each
should be 200 kHz wide that you can send to an FM demodulator path.
