Hello Marcus,
I am surprised the following command ran successfully.
$ pybombs -vv recipes add gr-recipes git+

If you want strict control over the file-size, then you'll likely need
to write your own block.
It should perhaps NOT come as a surprise that there aren't examples that
cover every possible use case, since the field-of-endeavor is
essentially-infinite, and there's only a finite number of entities
Make a new block based on the original?

Hi Pablo,
yes, you could do that "upstream", but since the functionality is
fundamentally different from what Max currently does, I think it'd be
better to simply implement it in your own Out-Of-Tree module.
If your let's call it "max_and_environment" block works well and you can
also write unit
There are a whack of approaches to doing this.
The filename parameter of the filesink block is runtime changeable.
You could have an external process using controlport or xmlrpc to change
this setting (from a variable) at regular intervals. The existing file
will be closed, and a new one start

Hey Mallesham,
I don't have the time right now to check your code but have you also
adjusted block [1] accordingly like I mentioned in my last mail?
It now needs to operate on complex float data.

Hi all,
I want to modify the block Max: instead calculate a maximum, I want to
calculate the maximum and two bins (two points) on each side and do a
average with this three values. Should I modify this code?[1]
Any help is welcome.
Best regards,

Hi Mallesham,
could you explain what of Julian's answer you did not understand? I
would have pretty much given you exactly the same answer.

Hi all,
I am scanning the wifi entire band to collect the raw IQ samples instead of
having fft as in usrp_spectrum_sense.py. Can anyone throw some light on it?
As of now, I am trying with approach given by Julian as below:

Hello Nicolas,
Thanks for your reply. I have sufficient disk space, more than 400 GB, so
that is not an issue. I do not have any .gitconfig file in my home
directory. I can download the recipes manually using the command you
mentioned.
git clone https://github.com/gnuradio/gr-recipes.git gr-rec
No, you can't convert a python flow graph to a GRC flow graph – Python
is simply able to do things like "if (foo) then connect these two
blocks", which you can't represent in GRC.

Hi Soumaya,
could you please keep the mailing list in the loop?
Well, on USB2, the maximum sampling rate is, if I remember correctly,
somewhere between 8 MS/s and 10 MS/s. Maybe the raspberry Pi isn't the
optimal platform for broadband signal observation...

Hi Soumaya,
while tuning, there will simply be transients, mostly of oscillator
energy leaking into the receiver. You cannot use the data that you get
while tuning.
You might want to define "strange power values"; 2.4 GHz is an ISM band,
so a lot of traffic is to be expected there, and that traff

Hello Usman,
uhm, this is odd. So far I can see the command is correct. Although error
128 means that git did not exit cleanly, and I just run it and it ran fine.
Just some guesses for now:

space, though, but not enough sp
