Has anybody managed to interface Gnuradio with Red Pitaya
(http://redpitaya.com) hardware ? Any opinions about this project ?
While looking for (more or less) affordable SDR hardware I find the
dynamic range of a 14bit ADC interesting.
tnx Mark

I just updated pybombs to the latest git version by using git remote update

that - if not defined - leads to an infinite number of make processes

audio DSP software as well. I was inspired to do this because I was

I tried building airprobe with the latest 3.6 build (3.6.5.1) and even

Can someone probably point us to a gnuradio version that definitely

That is difficult to say. I usually just run pybombs update every now

should do so in the future :-) ).

I tried rebuilding gr-air-modes with make -j1 both for build and
install, but it did no help. I even changed the generic makewidth
setting to 1 and rebuilt gnuradio, rtl_sdr..., but the problem is still
there.

Two suggestions from my side:
If you want to use Python, you can use the Spyder IDE
(https://code.google.com/p/spyderlib/). Spyder is mainly designed for
scientific programming. It even has built-in plotting capabilities.
Another package I have used for that purpose is kst-plot. It is fast and

Kevin, are you building gnuradio via PyBombs ? In this case you must
have doxygen installed on your system. Then you have to edit the build
recipe for gnuradio to enable doxygen:
open the file gnuradio.lwr in your pybombs/recipes folder.
in the line starting with var config_opt change -DENABLE_DOXY
May I then suggest to enable the docs in the pybombs recipe by default
as well ?

I just had the experience of how much the documentation build process
can slow down the build in general. So I think a flag that can be
set/unset during the pybombs configuration / reconfiguration process is
a good idea. And it would make it easier for new users who a: most
likely want documentatio
This is awesome. How did you analyze the data ? Is the software/source

Hi Aylons,
I have no answer here. But talking about Gnuradio and nuclear physics I

Would it be possible to use Gnuradio in a (home made) Gamma Spectrometer

measures the pulse height coming fro
do the data acquisition with a DC to HF (direct sample)
modded RTL-SDR dongle. The interesting parameter in this case would be

I am using several Newsky TV28T dongles. They are fairly cheap (kit with
cables ~£15, dongle only ~10) and work well with Gnuradio and related
applications. Just check on ebay for keywords like Newsky TV28 or
RTL-SDR and you will find vendors.
