When I was trying to replicate the flowgraph in my 3.8.2.0 version of
GNURadio. I got an FFT size error message:
return _qtgui_swig.freq_sink_f_make(fftsize, wintype, fc, bw,
name, nconnections, parent)
RuntimeError: freq_sink: FFT size must be > 16 and < 16384.
Then I tried to increase the FFT size to 17 and then the flowgraph was
executed but the flowgraph was not the same as shown in the example.
Attaching the flowgraph for the reference
My question is whether I have built the flowgraph in the wrong manner
or is it with the GNURadio 3.8 issue??
