Hi Rakesh
Thanks a lot.
The grc have run after adding the PYTHONPATH.
I tested the grc using the simple blocks:
signal source 32k -- Throttle 32k -- Scope Sink 32k
(Accessories is Capture Screen )
And then press Execute button

Hi Josh,
Thanks for the answer. But my problem is not exactly about the subject
you answer. To make it clear i will simply specify my problem.
I set an array on matlab which includes non-integer values (like
0.001, -0.253, ...) and form a binary file by using fopen, fwrite
commands then obtain a
More information about my problem.

After running the USRP2 GNU Radio example usrp2_wfm_rcv.py I got an error
which I cannot find the solution in internet, any ideas?
Many thanks in advance.

Howdy,
How well does GNURadio + GRC play with multicore processors? I'm running a
program that streams video on an Intel Atom-based processors and it's not
really able to keep up. I was going to try out the dual-core Atom's if
GNURadio would play nicely with it.
Thanks.

I'm trying to get this into as small a package as possible, because it's

Hi all,
I'm observing that rx handlers are called when 371 samples are ready,
I thought (I don't remember why
I have 370 hard coded in my code) the chunks where 370 samples. Has
this changed lately or it has been
always like this?
Is there a way to know in advance with how many samples the
