Hi, 1) use "--tune-delay" with 10e-3
2) Uncomment : #self.connect(self.u, s2v, fft, c2mag, log, stats) 3) Comment: self.connect(self.u, s2v, fft, c2mag, stats) 4) Change the line : self.max_center_freq = self.min_center_freq + (nsteps * self.freq_step) to be : self.max_center_freq = self.min_center_freq + ((nsteps-1) *self.freq_step) 5) Redo your experiments again!!.
