Thank you all for your postings! I really appreciate your help in
solving my problem.
Sean,
interesting point.
Frederik,
How does your carrier look when you send bursts of >500 samples?

Hello
I am trying to install an OOT module into my GNURadio distribution. I
can integrate the module into GRC and use it in the flowgraph. However,
when I try to execute, I get the following Error:

Hi Sebastian,
google showed that the wimax scanner project is hosted at
http://code.google.com/p/wimax-scanner/
and that they even have a mailing list, especially since that page shows no
connection of that project to GNU Radio.
Greetings,
Marcus

No, I did not mean that.
Ok, this might be a problem: "Scaling", for me, means "multiplying with a scalar
value".
My suggestion therefore was that you just insert a multiplier before the IFFT.
Maybe we're talking about a different "scaling"?

Marcus

Vlad,
thanks for going through the guided tutorials, and thanks for your
feedback. We'll address those soon and fix the tutorials.
As for your solution, I'm not sure. I recommend putting a couple of
print statements so you can tell what's going on.

Michael,
we do point out in our tutorials that you require GNU Radio 3.7.4 or
later to run these tutorials. The possibility of writing Python-only
OOTs is the main reason for this.
However, you *probably* don't need to upgrade if you don't like. One way
to do this is to clone gr-tutorial, and rem

Hi Martin,
Thanks for the response. I'll make sure to work with the newer version
going forward.
I see that the tutorial home page says 3.7.4 is required, but I just
checked the guided tutorial in python (

Hi again.
I finally was able to build most of GR using CMake and
the generated "Visual Studio 2010" gnuradio.sln file. Since I'm
not sure if this platform is supported or not, it may be a futile attempt.
I patched cmake/msvc/config.h since I figured that was the active one.
IMHO it's confusing

I often use the unpacked_to_packed block inline as well to save space and
transfer time if I am saving a bunch of decoded data. This may not be an
issue if you aren't doing things remotely.

Hello,
I had experimented with simple PSK reception with GNU-Radio when the
carrier is directly phase modulated.
However I would like to know how can I demodulate a PSK transmission which
is carried over a typical FM signal.
Kind regards,

Hello Everyone,
I hate asking questions like this, but I need help installing GNU Radio.
The objective is to have GNU Radio 3.7.5.1 and UHD installed on Ubuntu
14.04 so I can use it with my USRP N210. The problem I have is this:
1) I don't like using the ettus easy install for 'UHD+GNU Radio' bec
I just installed gnuradio using PyBombs on an Ubuntu 14.04 machine and it
worked fine except for two things. First, I had to manually install via
apt-get the boost library. I am not sure why but PyBombs kept bombing out
with an error. Then, after installation, I had to run ./pybombs env to
setup th
If you want to do it the hard way, i.e. installing the dependencies from
scratch and building from source, I keep an updated list here; ignore the
date:

IIRC you would just do the WBFM demod, then the PSK demod. See the gr-rds:

Hello,
I just installed PyBOMBS on Ubuntu 14.04. I'm noticing that sometimes the
icon labels are readable, but a lot of them are off the screen and can't be
selected, like UHD. The last icon available to install for me when this
happens is osmo-tetra.
To overcome this, I close PyBOMBS and restart
