Hi,
for those who haven't yet read Tom's recent blog post, I recommend
it--in a sentence, the lack of applications is hurting GNU Radio, and I
couldn't agree more.
One way to remedy this might be GSoC. Developing a nice application,
paid by Google... doesn't that sound like the perfect thing to d
Hi all,
I'm trying to read the real-time value of a stream from USRP. I'm
considering using gr.probe_signal_f, but it seems to not work. I'm really
new to GNURadio, so please forgive me if I ask some stupid question.
My method is like this:
#First generate a source from USRP:

How about a whole web application which would not exist without GNU Radio?

Without a monetization strategy I don't see how the gnu radio project gets much
past its current state. The problem is the functionality of a prototyper or
student is implemented in about 20% of the effort for a full application. The
documentation, testing, deployment, and maintenance of a real
I really think that projects like the ones in CGRAN have great value.
The key point in my option is to implement some widely used standards
_using_ the gnuradio framework.
As examples I'd say TV broadcast standards like DVB, ISDB-Tb, radio
standards like DAB, DRM, ..., this will greatly improve Gn

We have the developers's call this Thursday (third Thursday as usual). The
agenda is posted here:
http://gnuradio.org/redmine/projects/gnuradio/wiki/Call20120216
Unfortunately, I have a time conflict at the normal start time (6 PM EST,
2300 UTC) this week. If no one objects, I suggest moving it f
Tom makes the point that Gnu Radio isn't "shiny". Indeed, it isn't.
Some people arrive at Gnu Radio expecting that it is an "end
application", and walk away badly disappointed. They have in their mind
a firm notion of what constitutes a "radio", and fully expect that Gnu

I'm a little surprised by this discussion. I think GNU Radio is
positively amazing for prototyping, testing, and academic
purposes. I can't imagine making finished
The "you'd have to get all the dependencies right" is no different
than any other advanced application out there.
Things like "gimp" and
"blender" and a whole whack of others these days have a huge dependency
tree. Gnu Radio is no different.

hello!
i'm a new user embarking on some exploration to evaluate GNUradio and
the USRP platform for some multichannel radio monitoring. i am starting
with sample file processing before buying any hardware, as CPU usage is
my chief concern.
my problem is with using a large sample file capture
It's very likely that your on-disk sample format isn't what you've
declared to Gnu Radio, and it's seeing some garbage numbers.
Is it
possible that it's stored as 16-bit I 16-bit Q in the file? If so,
you'll need to convert it before any of your complex-float blocks do
anything with it.

That was just a little something for the Firefly fans in the audience.
Good perspectives, everyone, thanks!

If this helps, you can precisely time transmit packets using stream
tags. If you know the time when a transmit occurs, you can intelligently
mute your receiver. See notes in uhd_usrp_sink.h
Also, it has just occurred to me that my stream selector block does not
forward stream tags. - Mental note t
There's been a ton of work going on in getting us ready to really start
using Volk in GNU Radio blocks. Instead of repeating myself, here, you can

Hi Tom,
Thank you very much for your detailed explanation. That really works!
I really want to learn more about GNURadio by myself. But I don’t know how
should I go on. How can I find the right function/module/block for some
specific purpose? Do you have any suggestion?
Thanks again.
http://gnuradio.org/doc/doxygen/modules.html is a good place to browse what
available.
