Hi Ben,
yes, that should work; as you've guessed, the polyphase channelizer
doesn't really "care" what your filter looks like. That includes the
band edges, too, so your last channel will overlap with your first.
Best regards,
Marcus

Hey community,
It is time for another project update. So here it is.
This week I dived into C++ and FECAPI. I implemented a polar encoder for
FECAPI. Of course this includes all the necessary tests. I decided to go
with packed bits in the encoder definition. Though I implemented a mode

Hi,
I need a GnuRadio debian package for version 3.7.7.1 to be installed in
many different computers. I've tried creating it myself but I run into many
difficulties. For example the command gnuradio-config-info --prefix
--prefsdir --sysconfdir was pointing to the folder where I created the
debian.
Hi Murray,
you'd typically do something like:
cmake -DCMAKE_INSTALL_PREFIX=/usr ..
to match what debian expects.
Then, instead of simply installing stuff there, you install into your
fake root directory using
make
make install DESTDIR=/home/murray/fake_root/whatever
That will only bend around t

Thanks for that Marcus, I got around that first step.
My computer runs Ubuntu 12.04 with libboost 1.48 and it has a working

What happens when you change it? How does it affect performance?

I have updated my gnu radio from 3.7.2.1 to 3.7.7.1.
After the update when i am typing the "gnuradio-companion" it is getting open

successfully able to execute the graph.
The results are coming out

This means that the gnuradio-config-info was definitely built with
another version of boost (1.58) than what is found at the moment you
start it.

Hi Tiankun, Hi Tom,
I vaguely remember me wondering about that line. It comes from the
single threaded scheduler; back then, wondering, I came to the
conclusion that for the STS that it's probably been considered useful to
half the the "buffer usage ripple" that could occur when blocks started

Alphonso,
looks like you've found a bug! Here's how I debugged this (it's a good
and easy learning example):
- Build GNU Radio w/ debug symbols
- On my system, I need to allow core dumps: Run `ulimit -c unlimited`
- Then run the app, it'll produce a file called `core`
- Open that with gdb: gdb /u
That was the first thing I checked. No I don't have any config file in
there. I'm not sure where it's picking up these other settings.
I added a local config file to ~/.gnuradio with the same settings and now
they seem to be picked up correctly. Shrug. I had to install one last

I just ran a new pull, I don't see any updates related to gr-perf-monitorx,
so I think I already have that commit. Here is the pull details just in

Hello all,
I am familiar with the stream mux and tagged stream mux blocks. What I need
to do, however, is add a preamble to a stream of data only one time when
the radio first starts, and then never again while it runs.
Is there a clever way to do this using built in blocks?
v/r,
Rich

Well, yes, this is the source directory containing the unexpanded script and
resource files.
To run the comand you have to replace YOUR_INSTALL_PREFIX with the path prefix
you installed gnuradio to, e.g. /usr/local
Also, please keep the list in cc.
