gnuradio.org still down here (Oct. 4th, 8:39 UTC). I can see that a
whois update has happened last night, so maybe DNS has to sync.

Here in Germany it is available again; two hours ago it still was
unreachable.

How can we increase the bandwidth of the FFT plot. The bandwidth is only
0.1MHz, how can I increase that to at least 10MHz. Thanks.

Hi Antmrt,
The FFT plots (there are several available in GR) don't have a bandwidth
of their own, they just display the FFT magnitude of the input sample.
Frequencies are only for display and are usually calculated by the
sampling rate parameter you set. That has no effect on the plot itself,
but
Thanks Marcus, my problem is how to calibrate the scale on the FFT plot. e.g:
I'm feeding a signal of -30 dBm to the usrp and on the plot the value
becomes about -10 dBm

This is a completely different problem, is it? Bandwidth is orthogonal to the
concept of dynamic range and amplitude values.
Anyway, your FFT plot knows about complex samples; therefore, it displays dB relative to
the numeric value of 1.0; this has nothing to do with your input signal
power.
Just a quick update to say that the DNS issues have been identified and
fixed, and we are just waiting for everything to propagate. I'll send
another update with more detail after we get things started today at the
conference.

Hi everyone,
After a long break since June I am now back learning about Gnuradio. I
asked in June for a way to average vectors elementwise and Martin Braun
suggested the moving_average_Vff block in the gr-specest. He also said it
would be available PyBOMBS. Now update:
Since I had installed
I updated gr-specest so it would compile with 3.7, see my repo on
www.github.com/dfxx if you want to try that route. The changes were almost
all namespace stuff and cmake stuff, i.e. I don't think I broke anything.

Hi Jared,
this is how the XML validation works, yes. It's probably just an
artifact of whatever XML parser we're using, but we've all gotten used

Just ran into this one a while back, see the discussion I initiated on
Sept 17th with the subject line: Updating gr-specest to 3.7
Most of the CMakeList.txt files needed updating... in one way or another.

I am trying to create a rational_sync_block class in an out of tree

I have a pyhton program (see

I use lock/unlock to do the disconnection/reconnection.
However, I always get segfaults after a couple of changes.
The graph is pretty simple:

Hi Gui,
that's how most sample sources work anyway.
So just find the source that suits your needs best (in your case: Wav
file source), connect it to your signal processing blocks and run the
flowgraph. It will stop when the source signals that it's done, which
will happen when the file end is
Hi Achilleas,
after skimming through your code, I found no obvious mistakes so far.
My guess was that under some circumstances, you connect or disconnect a

why that should happen.

Have you imported all of the gnuradio files into the swig .i file that you

entirely sure what the two include declarations are for, but I
