hi community,
i just wanted to have a real time voice transmission between two usrp
boards. i tried tx_voice.py and rx_voice.py files. at the receiver i didn't
get anything. can anybody suggest me what to do to get the voice at
receiver.
thanks

Thank you friend,
where can i get tutorials regarding "how to use each block in GNU radio
companion"?
Thanks in Advance
any replies are appreciated

Hi All,
I just wanted to know if gnuradio has any appropriate guide on
using cmake instead of normally used cmake. All the tutorials and guides
written use old makefile.am utility. It would help me in my execution if
there are any gnuradio specific cmake reference.

Hi Ashish,
I have always found it difficult to measure the amplitude of each sample
using the floating point strengths. Things like frequency offset will
change the result and affect the individual samples.
However, calculation of average power based floating point strength works
for me. For exam

Hi everyone,
starting now, we would like to re-introduce the GNU Radio issue tracker.
If you don't know what I'm talking about, it's what you get when you
click 'Issues' on our website:
http://gnuradio.org/redmine/projects/gnuradio/issues
The issue tracker has been unmaintained for quite a while,

I am not sure if you can see the picture attached, so I print out the

Change the Receiver gain and see if the strength/amplitude of the floating
points change or not. If they do, then you are doing the right thing. You
can place a signal calibrator (e.g. some variable attenuator) to calibrate
the floating point strengths and actual received power.

Does anybody know the value of noutput_items in the work function. Is it
possible to access a specific number of bits/bytes of a frame in GNURadio? How
can I know the frame size which is passed from one block to another?
Regards.

Hi, I haven't run the bbn-code with gnuradio 3.6 but I did with 3.3. The
omnitreads aren't used anymore so try to include pthread instead. I believe it
will be possible to get it running.

A recent post by Markus Gonser had me intrigued and so I experimented
with his grc code. The resulting FM receiver does work but it doesn't
quite sound right. My guess is that the quadrature rate is not correct
at 705.6kHz. Is this the correct rate and if it's not what should it be?

Hi all,
I want to create a signal processing block that it will have variable number of

is uhd wants to calibrate LFRX board, and I don't know how to specify t
Hi all,
For calculating the amplitude (assume RMS amplitude) of a signal source, I
first tried to record the received samples (I'm using a vector signal
generator) in a file_sink and then thought to use it for my calculation.
The frequency of the signal from the signal generator was set to 400M a
