Does the GRC output block re-order output? I’m puzzled with respect to
what I’m seeing.
My normal expectation is that, given an FFT buffer of size N, that on
output
buf[0] to buf[N/2] = DC to nyquist
buf[N/2] to buf[N] = -nyquist to DC
But that isn’t what I’m seeing in GRC FFT output. Clues?

Send the generated python code so we can see how the fft block is
created.

Seems correct.

Never mind. It was my own problem, nothing to do with GRC. Carry
on. Nothing to see here.
