I have had no problems installing Gnu Radio under Kubuntu.
If you already have a potent machine, try that. It gives the added bonus of
being much prettier than Gnome ;)

hi Marcus,
I am attaching the screen shots and also block diagram of transmitter..
right now i am just trying to look for transmission of OFDM signal via
usrp1. As i mentioned earlier in the fft scope plot in gnu radio i see the

I’m using gnuradio-3.3.0 with GRC.
I’ve builded a graph with a Complex cosine (8Ms/s of sample rate and 1 MHz of
frequency), the fractional interpolator with 12/8 value for interpolation and a
FFT sink with 12MS/s of sample rate. (throttle block included).
I’m expecting to see a 1MHz cosine with

Uhm, so it’s a little bit confusing.
Another strange problem is that if i put a 0.64 value of interpolation, and my
flow graph is a file souce->fractional interpolator->file sink, and my source
file is 1GB of data, i’m expecting a 1GB*1/0.64 output filesize. But when i run
the graph i get a 800M
Sorry, the filesize is my mistake. All okay now. Thank you.

Glad to hear it works; I guess zip() cant be used with swig'd vectors on
some platforms (my best guess).
I reworked the code a bit to my liking and it should also fix this

I tried with the E100's actual address and the loopback address (127.0.0.1) and
both worked. I should also say it's a bit confusing to call the command line
switch "--address" when it's actually handling the arguments the same way as
uhd_find_devices, etc. handle the "--args" switch. For instanc

Also in benchmark_tx.py I noticed that calling "-m qpsk" and "-m bpsk" still
default to their differential versions unless I explicitly use the
"--non-differential" switch. Was this intended? I assumed that specifying
"*psk" vs. "d*psk" would do the right thing.
Thanks,
Sean
P.S. - Thank you f

Hi all,
I am facing "Segmentation Fault" error.
My setup is - Ubuntu 11.04, USRP2 with WBX board, gnuradio.
The scenario is - When I run uhd_fft.py, I get the following -

Starting program: /usr/bin/python /usr/local/bin/uhd_fft.py

One more thing - it looks like BITRATE refers to the USRP sample rate as
opposed to the bitrate of the modulation scheme. I think this is a little
confusing. Please correct me if I'm wrong with this math, using QPSK as an

ok so this has been working just fine at home,
but i am actually beginning to use the usrp in performances fairly regularly,
and you never know what might happen in such situations…
so just to be on the safe side, i'd really rather replace the fan.

Yes I have. I disconnected it. In my opinion, it is overkill for anything
going on in a USRP1.
YMMV,

Ah good, glad to hear it's not just me…
Do you run it with the top on or leave it open?
Cheers,
