How to edit Ted Cline’s GNU Radio ezCol-style data collector to change the FFT

Question:

I’ve got this working with Airspy Mini SDR but FFT limited to 256 – as I am using the full 6MHz bandwidth, I’d like to be able to change the FFT to 1024 or 4096 – any chance you could do quick modification of the code to allow changes in FFT to be made with a parameter? 

Answer:

I think you mean edit my GNU Radio collector ?

I do not easily have the hardware to test.

I attach 3 images, so that you can edit it yourself:

A.

Edit the embedded ezColSink block, with the   Open in Editor   button.

B.

Change the 2 parameters, from the “256” values I gave you.

Choose a new freqBin, use a power of 2: 512, 1024, 2048, or 4096, …

Save your changes.

C.

Update the GNU Radio 2 variables to match your new freqBin choice,

      vec_length

      freqBinQty

I think that is all.

Ted
