Hi,
osmosdr.source is the name in gnuradio 3.7.x version
osmosdr.source_c is the name in gnuradio 3.6.x version
Are you sure your application is compatible with gnuradio 3.6.x ?
Cheers,

Hi,
Thanks. Rebuilding Pybombs with Ice 3.5.0 helped.

Hey,
an updated version of my GSoC proposal is now on available:

Hi,
I try to send square wave from one USRP to another.
The received signal at the receiver USRP is very different from what
was being sent.
This is just a very simple setup. What could be wrong ..?
Apparently your understanding of how things work :)

What you are seeing is a classic case of frequency/phase

Hi,
looks like a version issue. Try updating to PyGTK 2.22 or above.

I opened an issue on gnuradio.org for this.

You can pull a fix from:

Let me know if that works for you.

So I tried out the PyBombs install method as documented on the wiki. Very
nice. No worries about missing pieces, almost.
Apparently the version that is out there doesn't know how to make
python-lxml. I also cannot get the build to complete due to what appears to
be an issue with libusb.

Hi,
A couple of questions:
- Good detail on your deliverables!
- Do you have access to a real VNA to compare results with the GR solution?
More generally what hardware do you have access to or can you get by
yourself ? Just to know what we would need to provide.
Cheers,
Sylvain
Hi Mitul,
one suggestion regarding the output of the VNA: since you do scattered
parameters calculation, you may want to include also b, Y, h, z (I think you
calculate this) parameters output. Here is an old Agilent app note with
formulas between those parameters in appendix B:

Thanks for bringing this up. Simply stated, the goal of this New Users Day
is:
- Increase visibility for GNU Radio, possibly touching new professional
and social circles where GNU Radio isn't used yet
- Help new users understand what GNU Radio is, and how to use it
In some ways
I'd be happy to help! I'm sure classroom-style lectures will be covered by a
few people who have already presented the material a bunch of times (Tom,
Johnathan, etc.). Maybe you could use a bunch of more experienced GR people in
small breakout sessions or to oversee hands-on tutorials, etc.

I have to procure a couple of laptops with Gig-E port for working with N

Hello community,
Two weeks have passed since I added my idea MIMO Transceiver on GR GSoC
webpage. In the past few days, I tried to carry my project a step forward.
I did some reading and made some tests on MIMO CSI estimation. Seems
everything goes as I expected.
