Hello Bernardo Gonçalves:
No, I have not yet obtained any other materials/flowgraphs other than what
Markus Heller posted on this mail list. However, I do not have time to look
into the FM radio TX/RX right now as I am very busy trying to finish something
else. I will start working on it again
Greetings,
Yesterday I updated my gnuradio/next and UHD installations to:
UHD_0001.20101204162446.a51fb2e
v3.3.1git-322-ge92f2cb6
I noticed that when changing USRP sample rates using
uhd_single_usrp_source the flowgraph will suspend execution and CPU
load drops to 0.
The flowgraph is still alive
Hi,
I am new to gnu radio and I have a dat file (complex or float) captured from
file sink which was directly connected USRP.
Can anyone help me with how to see the data in the dat file as i was trying
with octave but i dont know much about octave too.
Abhijeet.
Use gnuradio-companion and connect a file source - throttle - scope or
fft sink. http://gnuradio.org/redmine/wiki/1/GNURadioCompanion

HI,
I would like to configure two USRP2+RFX2400 boards one as the TX only
and the other one as RX only, so on the TX board I set:
io_tx_05=1 = the enable(pin 8)of the transmitter mixer (U101) is
always high, so the mixer is always active
io_tx_06=0 = the TX/RX (U202) works always as TX

Nope, that's not a typo, just a (possibly bad) joke. The

What version of GNU Radio are you using?
What OS, distribution and version?
What hardware are you running it on?
How much memory does the machine have?

Can you pull the latest gnuradio next branch? I reverted some changes
with the tags until we can re-group. You may have run into an issue with
the work function implementation.
Let me know if that resolves the issue.

Hi, all
I want to plot a figure with the samples from usrp, but I have some questions.

Anyone know how I can get extra linker options passed in for FFTW3F

The Gnu Radio build system is, well, fiendishly complicated, and doing
the obvious:

Hello:
Does GNU Radio keep track of time, or sample count, or something similar as a
flowgraph runs? How can I query the current flowgraph time, from within my
flowgraph, if such a thing exists?
More specifically, I have a Signal Source connected to a USRP2 Sink in order to
generate a tone.

I did some tests tonight using the multi-thread support in FFTW3.
The changes to gri_fft.cc were relatively minor, but plugging this into
the existing build environment
will require a little surgery, since you need to add -lfftw3f_threads
to the ld flags, and the ld flags
for FFTW3F are

Dear Matt,
how and where does the truncation is done? is it in the FPGA (DDC) ?

I'm running GNU Radio 3.3.0 with two USRP2+WBX, under openSUSE 11.2. Sometimes
when I run my simple flowgraph (Signal Source -- USRP2 Sink), either from GRC
