Nice. I don't know much about radar. Is range related to EIRP?

It is dependent on sample rate of graph. You may check this video for
an example to transmit 9600 bps GFSK
https://www.youtube.com/watch?v=N1hR6VgWeow&feature=youtu.be
In this case, sample rate effectively set by throttle block because of
no real hardware:
96000 samples/second
GFSK modulator:
10
Fortunately, the rate is set by the USRP sample rate, not by the rate of
the UDP block.

I am working a project where I need to receive bytes via a UDP source,
encode as GMSK and transmit via Ettus UHD.
My main question is how do I set the bit rate since I really cannot control
the UDP source? My receiving radio is expecting 9600 bps.
Thank you,

I'm having real trouble understanding what you're doing.
Try this: generate white noise and put it into the detector. Do you see
any 1s? I would guess no.

Never mind. It looks like there's a timeout before which the user can select
"no" to running volk_profile.

Is there a clean way to skip volk_profile when rebuilding gnuradio with
PyBOMBS? This setting seems to be automated and I can't find where to switch it
off.
Thanks,

A challenge that I am encountering recently when building flow graphs is with
upsampling and downsampling and getting the sample rate where I need it.
Sometimes I have rate mismatches and don't know a good way to take measurements
with grc so I can troubleshoot. Is there a nifty way to measure t

Hi,
The Radar Toolbox has new features!
First new feature of the Radar Toolbox is a Dual CW Radar. It is
implemented as simulation and tested with USRPs. This setup is much more
better than the previous FSK Radar!
Check out my development blog for a demonstration video and further
information. [0

Hi there,
Could someone help me fix this issue, when I try to run my tests, the ctest
returns the following:

Nonetheless, when I import any module from gnuradio in python terminal, it

Hi Xianda,
how should we possibly tell? You expect us to be able to guess what is
going wrong with your measurement, in an environment that is unknown
to us, using a receiving antenna, modified flowgraph and tx signal
that you did not really define.
Hi there,
I have modified the delay block of baz to control it from a clock of
seconds.
But I do not know if this is the best implementation... :S
Greetings.

Hi Martin:
Thank you very much.But I test again and again,the rx_detect
