Hi,
We are experimenting with two USRP1's (each with RFX2400) and noticed
some strange behavior. We use the
/usr/local/share/gnuradio/examples/digital/benchmark_rx[tx].py. We run
it once and the number of corrupted/lost packets is rather small, say
0-2%. Without modifying any default values of par
I just upgraded 10.04 to 10.10 and compiled gnuradio from git
repository without any problems, thus I would just use instructions
for 10.04.

Thank you Michael for your efforts. Would that mean it is just an
issue with the test, not with the gnuradio compilation itself?

Hi,
I'm using the digital/benchmark_*.py from the GIT repository and am
getting a very low ratio of corrupt packets, usually under 0.5%. I use
the default gmsk modulation, USRP1's with RFX2400 and run the
benchmark with a frequency of 2.4G. Would this low ratio suggest that
the FEC is being applie
Hi,
I would like to be able to change modulation scheme and other
parameters on the fly, from within a separate process. I'm using a
modified version of the tunnel.py from the GIT repository, which
instead of forwarding the packets to/from TUN/TAP device, acts as a
CORBA server with registered cal

Hi everyone,
I am trying to use the GNU-Radio+USRP to implement a cognitive radio
use case in which radios exchange information (XML-based documents)
between each other in order to achieve a defined goal (e.g. to improve
connectivity), without disturbing the usual communication. I have

Hi Michael,
my intention is to allow a communication between two USRP's hooked up
to two different computers. Each USRP has one RFX2400 daughterboard
and one antenna connected to the Tx/Rx port. I have a more of a CS
than ECE background and my focus here is on the application level. I

I've been browsing through the mailing list archives to find some

Sheng,
are you familiar with OSSIE project (http://ossie.mprg.org) ? It's an
open source SCA implementation and they use USRP as their RF front
end. Perhaps that could be a better place to start. However, I'm not
sure what is your ultimate goal.

Hello,
I am debating whether to buy USRP or USRP2.. Is there any progress on
the USRP2 drivers for the Mac OS X? It seems that the USRP2 FAQ hasn't
been updated for a while - as far as this issue is concerned.
Thanks,
Jakub.

Discuss-gnuradio maili
Hello all,
I recently installed gnuradio (3.2.x) on my machine (OS X) and was
wondering about purchasing the USRP. It seems that usrp2 is currently
only supported on Linux, so I guess I shouldn't get that one. Can
anyone recommend daughterboards that would be best for simple
communication, e.g. fo
Hi Michael,
that would be great. I actually want to use CORBA along with GNU
Radio, so that would be perfect.
Thanks a lot for your help.

Any ideas? 3.1 compiled without any problem and I was able to run some
examples that didn't require USRP.
Thanks!

thank you for help! It turned out that I had set the DYLD_LIBRARY_PATH
for my Matlab, so that I could interface it with Java. Also, the
PKG_CONFIG_PATH hadn't been set at all. After removing the
DYLD_LIBRARY_PATH and setting the PKG_CONFIG_PATH I managed to compile
