Hello,
I have a USRP B100 from Ettus and I am receiving FM Radio. I plotted the RF
Spectrum and the baseband spectrum in a notebook, but I don't know how to
change the frequency axis or zoom in the graph. I want to know if it
possible to change the frequency in the same graph as well.
I tried to

Right; relative_rate as a

Hi list. My 1st post here.
I have a big problem with CMake and some of the generated
files under gr-filter/lib. E.g. here is a snippet from it:
#include "fir_filter_ccc.h"
#include

namespace gr {
namespace filter {

Hi,
What is the need for two types of work functions in a block(work and
general_work). Can't we do that behavioral with single work function?. Is
there any particular reason behind that.

Hi Siva,
yes, referring to the introductory tutorials I can explain:
gr::block, the mother of all blocks that can process samples, has
general_work. That gets called to process samples, but does not make
any guarantees about the ratio of the numbers
Seems more viable to run it on a more modern cpu, such as

Hi Murat,
It was easy to install GNU Radio on the Raspberry Pi. I started with the
2014-01-07-wheezy-raspbian distribution.
Add the following entry to the /etc/apt/sources.list file:
deb http://mirrordirector.raspbian.org/raspbian/ jessie main contrib
non-free rpi
sudo apt-get update
sudo apt-
Having some issues with Control Port and Perf Mon in GRC.
1. Built Latest Gnuradio 3.7.2 from git.
enabled performance counters in the cmake command line
cmake ../ -DENABLE_PERFORMANCE_COUNTERS=On
then successful make, install, ldconfig, and gnuradio runs fine.
2. Edited the gnura
Dear Sir,
I am using the built-in block of Vector Source, configured as below:
Output Type = Complex.
Vector = ( 1, 2, 3 )
Then I run the flow graph.
The block sends out 1 + 0i, 2 + 0i, 3 + 0i.
Question:
How to make it sends 1 + 2i ?
(How to configure this at the Vector field?)

Hi activecat,
have you just tried the most intuitive options:
Vector = ( 1 + 2j, 2 + 4.0 * 1j, complex(3,-1) )
all three elements work, since this is just python :)
Greetings,
Marcus

Dear Marcus,
Thanks, it accepts ( complex(1,2), complex(3,4), complex(5,6) ).
The other two are not accepted, message:
name 'j' is not defined.
Nevertheless, that is good enough.
Thanks.
