Re: Problem with Log Power FFT block

Actually, I did make a stupid  mistake in the stream-vector block  - there's no problem - it works as expected under 3.8.2.

Hi Jeff - hmm, it appears the FFT block on 3.8.2 appears it doesn't like vectors?

On the 3.8.2 installation, could you try creating a new flowgraph from scratch that is just

  Signal Source -> Throttle -> FFT Log Power -> Null Sink

and see what happens?

Between 3.8.1 and 3.8.2, the line of code where you're seeing the error was removed. It was part of the yml file for that block.

Deleting and inserting again the block does not help. I can see the
problem even on flowchart created from scratch in GR 3.8
The problem exists on openSUSE Tumbleweed (GR 3.8.2), leap 15.2 (GR
3.8.1) and also in Windows port of 3.8.1 --
