Hi Daniel,
My name is Chris Roberts, I'm an MS student at Case Western Reserve
University. I'll try to outline my knowledge of the work with GNURadio I
am aware of.
I am currently finishing my thesis on an undergraduate laboratory
curriculum that uses GNURadio and the USRP.

Hello,
I experimented with many distributions and eventually settled on Fedora
Core 4 (just before 5 was released). Fedora installed well on the
machines I was using and there are installation scripts at
http://www.kd7lmo.net/ground_gnuradio_install.html to guide the GNU
Radio installation.

Hello everyone,
Has anyone worked with fsk_loopback.py? I have been analyzing it and
using a file with ascii characters as an input, but I get no output.
I am trying to develop a system that will transmit text from one machine
to another. Based on the FSK code, I first made this program:

I have investigated further and ran the qa_hilbter.py script.
The Hilbert transform repeatedly fails this test.
I am running GNURadio 2.8 on Redhat FC4.
Dual Athlon 64
4GB RAM
Any thoughts?
Thanks,
~Chris~

Hello gang,
Does anyone have working SSB modulator code? Both the code I have
written, as well as the code in the archives isn't working correctly for
me on the USRP, so I am seeking guidance.
Thanks,

Hello,
Does GNURadio have a magnitude or absolute value block? I found one
mentioned in the archives but don't see it in any of the documentation.

Hi Matt.
Thanks for your help. I restored Internet access to my Linux box and
was able to transfer the actual filter weights from MATLAB into GNURadio
and it worked. The roundoff error must have been causing the IIR filter
to go unstable.
Thanks,
~Chris~

Hello all,
I've been doing some experimentation with some very basic IIR filtering.
I am creating sinusoidal float sources with a sampling rate of 32Khz,
connecting them through the gr.iif_filter_ffd() block, and then output
the result to an audio sink and a spectrum scope. For my taps, I a

Hello,
I'm currently writing a set of laboratory exercises utilizing
MATLAB/Simulink and GNURadio/USRP that will introduce various
communications and digital signal processing concepts. I hope to
release them once I am finished so they should provide a walk through
of the system for newbies.
Hello,
I am using the same distro. I go in an chmod the usb directory every

Has anyone done any work with AM demodulation with the !Flex-400 DB? I
have seen the existing examples and have been working to write my own,
but I am getting the feeling my offsets are off.

Hello everyone,
I have been experimenting with the Flex400 board and have been trying to
implement a basic AM transmitter. I have a WFM and NFM transmitter
working, but I cannot get the AM one to transmit correctly. The code
below generates a much higher frequency tone. Any advice to what I am
I could help out with conversion.

Hello everyone,
I've been going through the GNU Radio examples the past week, and one
thing I've noticed is that many of them are clogged up with Powermate
code. The Powermate knob is not required equipment for GNURadio, so my
thought it that we should make a separate Powermate folder that conta

Hello everyone,
Is there anyone out there working with GNURadio on Windows with the USRP?
The current install files from Martin have one issue with the way that I
install them. When I attempt to run any of the USRP code it looks for

When I run the installer it fails to run the GNURadio-core install.
It installs the following packages in the following order:
USRP
USRP_prims
gr_usrp
gr-audio-windows
gr-wxgui
I'll grab the package and install by hand, just an FYI
Thanks!

Hello everyone
I have tried installing your GNURadio for Windows binaries following
the instructions posted on Martins website.

I have found the drivers for using the USRP in Windows. Is there any

files there were created from? In the latest usrp install there are

Hello everyone,
I realize this is slightly off topic, as it does not directly use
GNURadio, but I felt this would be the best forum to ask in.
Has anyone done any work or analysis of interfacing the USRP with
Matlab/Simulink and the Real Time Workshop?
Thanks,

Hi,
I was wondering if anyone knew the status for the Transceiver boards
for the USRP. I don't want to be nagging Mr Ettus. :-)
Sincerely,

PS - I should be releasing an improved Gnoppix CD soon hopefully.
