Hi all,
I have made an OUT-OF-TREE module, but now I want to remove it from
gnuradio. I am using GNUradio 3.7.3. Can anyone tell me how to that?
Thanks a lot

Dear Sirs,
I am performing fresh gnuradio installation using pybombs.
Pybombs install master branch by default.
How to make pybombs install 'maint' instead?
Act@rsLAPTOP: ~/download/pybombs $ git checkout maint
error: pathspec 'maint' did not match any file(s) known to git.

Hi Daniele,
your problem is actually harder: The latency of digital signal
processing depends on your desired decimation, and analog signal latency
depends on a ton of factors like target RF frequency, adjustable filters

Hello Stephan,
thank for your reply. What I would like to do is more simple than that:
I need to synchronize tx and rx of the same USRP, not of two different
devices. But I need continuous streaming and not burst.
Any help in this direction is much appreciated.
Thanks. Best,
Daniele

Hey Daniele,
I have done the radar toolbox and implemented a synced USRP interface
(USRP Echotimer).
You are right, the USRP Echotimer does align the timestamps of the TX/RX
commands on both USRPs. But if you connect them by MIMO, the time and
clock are pretty good in sync. Therefore I think the

There's no dedicated xcorr-block, but you can do a fast correlation

On top of what Marcus' has said,
the gr-radar toolbox might be helpful. It has a block that takes a
tagged stream, and outputs a signal it acquired synchronously to the
transmitted one.

I should note that want I really want to do is automate this measurement and
generate a series of curves that show TX_gain setting vs. intermod, for
several frequencies, at -3 dB from full scale. The state of GPIB support
under Linux doesn't seem to be that great though.
I suppose though that you
As Martin said, it really helps to have a spectrum analyzer. What I'll do is
generate a CW tone (sinusoid) of 0.707 Vp; that is 3 dB backed off from DAC
full scale power. Then I'll increase the TX gain setting until the TX image
rejection starts to become poor. This will typically be 15 dBm for

Hi all,
I've noticed that "Run to completion" works now in situation when
message passing is used, which is great!
I have a related question. I'm creating a block which uses message
passing, and run it once:
tb = some_block(fname="file1")
tb.start()
tb.wait()

Thanks, Sylvain
Looks to me it's not even gnuradio, but UHD.
"/usr/local/lib/libuhd.so" seems to be linked agains that version. I'm
not sure where you got that libuhd from but it seems to use a
different boost version than what you have now.

The CMake process may have its faults, but it won't randomly decide to
use a boost version not installed. Make sure there really is no boost
4.6 anywhere on your machine, and clear out the build dir.

Simone,
the actual tx power depends on a lot of parameters, and it is not a
simple setting. For one thing, it depends a lot on the actual signal you
are generating. If you need a very specific output power, you need to
calibrate your setup with a tool such as a spectrum analyzer.
In general, the
Hi at all,
I have problem to understand how an USRP used as a trasmitter works in term
of transmitted power when we fix a tx_gain.
Let me explain better:

100 mW of output power and a noise figure of 5 dB. (extracted from
