Geof:
You were right, and I installed the Intel x64 Fortran package available
here:

Unfortunately, I'm now getting python.exe crashes when launching GnuRadio
Companion. I'll try
You are already telling GR that you are decimating (nave in decim_block
init). BTW, you are setting self.nave to 0 in init, instead of using the
value passed in.
GR should always give you a multiple of 4 vectors (I think) since you've
specified a decim of 4.

Thanks Jeff,
I’ll give that a try.
I think I’m also missing something that tells gnu radio what the expected
decimation is (?),
beyond the decimate = 4 parameter(?).
Also concerning your point, then if I have a non-multiple of 4 vectors I guess
I need

in[0] is not the first vector, it is all of the available input for port
0. So, you feed in 4 vectors in your test program, and the shape of
in[0] is (4,1024). You're missing a loop that iterates over the input
vectors.

On the windows side, there is a tool called Dependency Walker that has been
really vital for me to track down missing DLL's. To use it here,

What is the actual amplitude where it fails? Many of the clock sync blocks
in GR expect a signal between -1.0 and +1.0, though I am not sure about the
PFB Clock Sync.

Dear All,
I am using the pfb_clock_sync to estimate the timing offset in my QPSK
receiver and I have a problem that I would like to ask about.
Basically if the amplitude of the incoming signal is set relatively high
(havent checked what actual threshold is) the flowgraph just hangs. After
