Videos from this year's FOSDEM are starting to trickle in. You can find
them at [1], but I'll (or we'll) try and keep [2] up to date, as well.
Cheers,

I just want to start capturing on both channels of a B210 at the exact

Subject: [Discuss-gnuradio] Trouble with SWIG for packet_formatte
Hi all,
Whenever I want to trigger USRP with at given time with use of a GPSDO
I'm adding something like this at the end of a constructor of a topblock
generated by gnuradio-companion:

self.start_time_epoch =
time.mktime(time.strptime(start_time,'%d.%m.%Y %H
Hi all -
I'm working on Tom's packet_handling branch (github.com/trondeau/gnuradio.git)
and building a custom packet formatter. Everything works in C++ land, including
QA code. However, SWIG is complaining about undeclared things. I duplicated the
CMake and SWIG structures of gnuradio/gr-digita

Thanks Marcus, and adding some more details. Current signal detection
mechanisms for years totally rely on signal attributes (frequency, timing,
amplitude) for differentiation of signals. Cognitive detection mechanisms
and new PHY layer techniques which emulate human eye like detection and

Hello,
I tried to build my first custom block.
Very easy. It just generates one tune msg every 5 seconds.
I followed steps of writing an OOT block in python:

Yes, that's how I understood this discussion.

I'm hoping for suggestions from the GRC and swig savvy folks on the list.
I am trying to add LDPC functionality to gr-fec [1]. I made a GRC block for a
decoder class. The decoder class constructor accepts a base class called
fec_mtrx. In GRC, I am trying to give the decoder block an input of an
Hi Marcus,
Thanks again for the detailed explanation of current access technologies. As
discussed current scheme allows shared access of the channels in time,
frequency, and space. What I am talking is about a full simultaneous
parallel use or access of channel. This is kind of necessity as wirele

"Unable to import Colors" is also a warning for me, but then I also get:

Which is an error. It looks like my flowgraph needs Colors afte

Hi all, Martin,
At this point I got confused about what I need for implementing message
passing and stream tagging reading capabilities.
At first I thought everything was implemented in GNURadio 3.7 (which I use)
