The fading can be seen as the notches in the top of the spectrum of the signal. Such fading creates problems in the recovery of the information. The signal does have a relatively high SNR (signal-to-noise ratio), but the fading makes recovery of the information using Gnu Radio impossible.)

By setting the "Gain" value in the Quadrature Demod block to samp_rate/(2*pi), the output will have amplitude values of the deviation of the FM carrier.)

This is a polar discriminator circuit. The input complex samples are split. One sample is sent to a Multiply block, while the second set are delayed and conjugated before being fed into the Multiply block. The output of the Multiply block will also be complex samples, except they are now the phase difference between consecutive samples. The Complex to Arg block calculates the actual phase, in radians, for each of these...)
