Thanks for the ideas, I could do that and Rgrep seems useful indeed.
However, I'm new to coding Gnuradio and would like to use the tools
provided as far as possible, i.e. I would very much like to use the
gr_modtool to help me with creating the xml files. But, after some
investigations it seems the
I was playing around with
fir_filter_XXX
and
freq_xlating_fir_filter_XXX
and noticed that the two do not give the same output
for the same input (and center_freq=0 in the xlating filter).
Looking at the implementation of the latter
it is obvious why: the taps are reversed in the line:

In the benchmark_tx.py code for MPSK modulation, the pfb_arbitrary_resampler
block is instantiated with 32 * 11 * floor(samples_per_symbol) taps. I
understand that 32 is the number of filters in the filterbank, but I'm not sure
what motivates the factor of 11. Has anybody been able to fine tune
One of our private GNU Radio training classes in San Antonio, TX, has
had a couple slots open up, and our customer is willing to allow 3rd
parties to attend. It's happening Oct. 21-25. The first three days is

Hi Tom and Chris,
Thanks for your detailed guidance on this. I'll try this out.

I did make uninstall and make clean in bladerf, gr-osmosdr and gqrx, then
rebuild it all, still this error:

`bladerf_fpga_version'

First of all, I'm sorry that I could not understand clearly what you want.
Are you using any hardware or you are just running a simulation using *GNU
Radio*? What do you mean by waveform of transmitter? How do you integrate
AM transmitter with FM receiver?
If you have USRP and want DSBSC AM, it is
I've described it like this:
Traditionally radios have been purpose-built for specific types of tasks using electronic components to perform those tasks. Many of the crucial "systems" in
a radio are actually performing mathematical "transformations" on the signals going through them. Sometimes
Hello every one...
can any buddy say , is it possible to make simulation of
enegergy detection based spectrum sensing without USRP or Fun-cube dongle
.???
if , yes . How?
guide me.
as per my opinion ..
it may be possible by redefine block which give frequency band
Avoiding jargon how might GNUradio, software defined radio be
explained to AM-FM radio listeners unfamiliar with technology generally?

Hi,
I'm new user of GNU. Can someone please help me in creating a flowgraph of
AM transmitter. I have to use it for communication of radio having a range
3-30 MHz. Receiver part is already done. I just wanted a waveform of
transmitter part only. I have to integrate this waveform with FM receiver.

I've been poking around in other GRC files to find examples. The ones in
specest are a little tough around the edges, but I've found the ones in
GNURadio/gr-fft and other sub blocks of GNURadio to be decent examples.
Rgrep has been helpful...

The filters all have "set_taps()" methods that allow you to set the taps dynamically.

Well, at least I made a git pull, make, sudo make install for bladerf.

Hi,
With latest versions of GR / bladerf / gqrx / gr-osmosdr again something is
stuck. Gqrx does not work anymore, I get the following error during make:

Hi again,
I uninstalled what I had installed through PyBOMBS and installed Gnuradio
3.7 through the build_gnuradio script. Then I tried Jareds repo for specest
with 3.7 (http://www.github.com/dfxx) and it seems to compile just fine,
well done! I can also import specest in python without problems.
