[Discuss-gnuradio] Calling functions from flowgraph ?

[Abouda Yassine]

Hi everybody,

well,I had a python script which works with gnuradio and outputs results on
the terminal.To make it more visual,I made all the blocks on the
gnuradio-comapnion but now I would like to output the results on the
terminal which means I have to call the main loop in the python script from
the flowgraph to get the job done.In other words,when I hit the button
execute the flowgraph,I want to see the porgram running.I hope you
understood what I'm trying to do.So,how can I do that?

regards,

[Discuss-gnuradio] a silly question about the sream to vector block

[Abouda Yassine]

Hi guys,

While i was trying to figure out what the stream to vector block does,I
understood that if I choose for example nitems=1024 and vector length=1,I
get in the output 1024 vectors of 1 item each.And when I was reading about
it
on this web page (
http://gnuradio.org/redmine/projects/gnuradio/wiki/TutorialsCoreConcepts),the
paragraph speaking about items tells exactly the opposite of what I
understood it means if nitems=1024 and vector length =1,i get in the output
only one item which size is 1024 .I need clarification about this subject
please!!!

best regards,
yassine

[Discuss-gnuradio] Problem with getting clear FM signals using the usrp e110

[Abouda Yassine]

Hello,
I followed this tutorial to build a simple FM receiver:
https://www.youtube.com/watch?v=KWeY2yqwVA0.I am using the USRP e110,my
problem is I am only getting noise.I tried to change blocks and parameters
and it worked for me when I deleted the rational resampler and made a 100k
as a sample_rate parameter.I get to hear FM radio stations but the quality
of the sound is very bad it's like on the SAW movie.Any one has a solution
on how to improve the sound qualitythx
