I amtrying to read a FM signal recorded as WAV file using GNU radioCompanion,
using python. I am attaching the .grc file used.
Ican clearly hear the recorded signal but reading the data gives anull ([] )
value.

1/5 is zero using integer division in python.
Try using float division

OK, this is getting too confusing for me:

The docs say that I need to set Scale to the inverse of the Length.
Ok, I interpret that as Length = 4000 and Scale = 1/4000
The docs here:
https://www.gnuradio.org/doc/doxygen/classgr_1_1blocks_1_1moving__average__ff.html
says that Scale is a float.
The discussion here clearly shows Scale working

Hi,
Question on changing the variable at run-time.
I want to change the sync words in OFDM carrier Allocator block at run-time. I
know that this will effect the receiver for packet synchronization/detection,
which I don’t care at the moment. My only target is to vary this sync word at a

Not only did that get rid of my obsolete heir blocks, but I took a chance
and deleted the code for the other heir blocks and re-generated them, and
now my seemingly bizarre errors are gone and things are working as well as
expected at this point. I will keep this in mind, it looks from

pi and gnuradio before i need help on how to integrate all of this

Do you mean the "compiled" Python and GRC scripts? Look in
"~/.grc_gnuradio/" and find the correct .py and .xml or .yml files &
"rm" them. Not sure what else you might mean, so hopefully this
helps! - MLD

I've created some heir blocks, and now I have some that I'd like to remove
from my list as they are obsolete.
How do I remove them?

Dear all,
I am using the FEC Extended Tagged Encoder block with a CC Encoder
Object. Everything is fine when there is no puncturing (meaning that P =
'11'). However when I want to add some puncturing, there is a problem of
tag. Indeed, the length tag is not updated depending on the puncturing
Error message "destination port 0 out of range for QSD Summing Amplifier(7)"
This heir has a pad source with four float streams and a pad sink with one
complex stream.
Everything is float, and everything is connected.
I assume the error above is talking about the pad sink.

Hi Julian,
thanks for your suggestion. I agree this is how I could work around my
issue. Though, another goal of my project is to minimize latency. A
'tx_time' tag that points to some 'distant' time in the future
contradicts that goal. Apparently, I forgot to add that to the list of
things I'm
