Yes, I use it for another project which is a pulse FMCW radar project
In this project, we need an LFM with receiving time (dead-time) for testing
the function of the radar (transmitter and receiver etc..)
Do you have any tutorial to modify the block of GNU Radio? I am a hardware

Hi Phil,
I read your post like four times and could not figure out what you are
doing and what you are trying to achieve. Where is your target signal
originally located? At fc? Is fc = 100k? Why do you mix 100k down with
the Frequency Xlating FIR and then define a different center frequency

yes. You will need the package that installs the headers, too; that's often
called
gnuradio-dev or gnuradio-devel.

Dear community
I've been trying to make a fully synchronous multi USRP transmitter in
GNURadio v3.8.2.0 and UHD v3.15.0.0.
In order to have a common clock and time between 2 USRPs, an octoclock
is also used.
when trying to run a flowgraph which consists one multi_usrp sink block
that is co
Okay, well best of luck with that. I hope the B200 has the necessary
capabilities to do what you need.
Here are the links to block writing, hope this helps.

Hi Fabian!
Yes I Xlating and filter the Bw to 100K and then decimating to SampRate 100k to
be get a morefine details in the GUI Frequency.
I tested with a second Xlating in parallel and it worked perfect.
PS. Is there any mirroring of this list with a WEB gui?
/Thanks

You are welcome, glad I could help :)
The list is mirrored here:

Hello everyone,
I am using the embedded python block in GRC to realize some simple
functions. All works fine in the GRC local set-up. However, if I connect a
USRP sink to the flowgraph which includes that python block, and set
the sample rate more than 20 MHz (I need 100 MHz in my case), it will k

Thank you for the quick reply, so if I write the block in C++ or C, it may
work at a higher rate?

It might be faster, and it will not compete with the rest of Python for the

Important point: you usually do *not* develop your software directly on the
embedded
platform (ie. your pi); you'd normally start on a PC, develop, figure out how
fast it runs

where do you set `d_finished = true;`?

Hi Marcus
I'm setting d_finished = true in the stop() function, like GNU Radio
message strobe do it:
bool
thread_ptr_impl::stop()
{
// Shut down the thread
d_finished = true;
d_thread->interrupt();
d_thread->join();
return block::stop();
}

Well, then behaviour is as intended:

I think you simply might not want to interrupt() the thread here?

I am not using a Raspberry Pi, I use a PC directly connecting to the USRP

So I suppose I can try C instead of python to speed it up, or maybe FPGA,
then I need time learn

Hi Marcus
I first deleted the interrupt in the stop() method but it didn't work.
After that, I read your link and it gave me an idea. I put a try-catch in
the boost::this_thread::sleep function to discover what interruption is
happening, and now, my program works as it should be and no kind of

Supporting 100Msps rates on an ordinary PC is exceedingly challenging for any
but the most trivial signal processing.
Even the most simple mathematical operation uses 10s or 100s of instructions
once you factor all the overhead of moving samples around, etc.
