Personally, I think a passive GSM attack would be more useful. Has that been
accomplished yet? I saw a scholarly article on it but I haven't seen any
articles/tutorials on cell hacks except the GSM attacks that require you to
transmit.

Kevin,
The radio is released properly when the destructor is called, but it's
not getting called for some reason. I have several C++ tests that work
like a champ, but the Python test doesn't actually release the resources
that were allocated. I even tried assigning my block that talks to

You're absolutely right about having hardware involved in the unit
tests. They are strictly for my internal testing. Testing the code live
in GNU Radio is turning out to be a serious headache =\

Very cool! Thanks so much for not only setting this up, but doing it in a
way that is repeatable by others. This could also be used by people who
want to set up private internal mirrors, which isn't an uncommon request.
Nice work!
Cheers,

I don't think this is an accident; when we run the tests on our CIs, we
want both the regular output and the XML output. You're right that this
behaviour can be annoying, however, I found if this is giving me
trouble, it's usually because my test is stateful. Maybe you can come up
with a way to

Well, looks like this was fixed may 2nd.

Hi,
this is not directly related to the gnuradio software but to the
gnuradio.org homepage:
gnuradio.org uses CloudFlare (CF) for some reason, and thus, users of
Tor have to solve (Google) captchas (possibly indefinitely) -- otherwise
they're simply blocked from reading the page, see [0].
I recently ran across this "bug":

Hi Berat,
Could you tell us what type of failure are you getting? You could copy and
paste the error here to the mailing list.
Also, after sourcing the setup_env.sh you should be able to run the in the
same shell the following command:
$ gnuradio-companion
to open the grc. Are you able to?
Hi all,I am a beginner user of USRP N210 for GNSS SDR applications. Yesterday,
I tried to install GNU Radio on ubuntu via PyBombs. The instructions I have
typed on Terminal are below:

Thanks!
Why not moving the zero stuffing downstream and use a polyphase arbitrary
resampler with RRC taps? I'm not familiar with performance comparison
between PFAR and FFT FIR Filter.

Among SDRs, there is no universal "model" for things like total gain,
acceptable baseband magnitudes, etc. Even if there were, expected
variations in analog behavior mean that you usually have to tweak things
to make it work across multiple hardware. That's just an attribute of
the analog world
Hi,
For several reasons I need to change the sample rate during runtime (i.e
flowgraph running) in my gnuradio program. I use Ettus X310 and receive

is the following:

Use a subdev spec of:

And specify the RX2 antenna for each channel.

UPDATE
Even without any Costa loop or clock recovery, it works. It seems that the
trouble was only the TX amplitude.

YEH ! it works now.
Only 2 major things to do :
1st - I multiplied the TX amplitude by 0.5 with a multiply const block
2nd - I used a Costa loop before my demod and it works great.

Hi Olivier,
I guess Nick already pointed out the important bits. Also, the warnings
GRC prints to the shell should help you.
Could you solve your file source issues? Your questions here seem to be
related to a different issue.
