I assume you know what you're doing, but just in case someone reads this
who doesn't, the recommended way is

Hi all,
I'm using build-gnuradio script to build gnuradio and uhd. It works well

Hello everyone,
I am having the following problem on an x86_64 linux machine:
When I use the ZIP-release (currently 3.5.2.1, using configure&make)
from the GNUradio homepage to build GNUradio, the python shared
libraries always get installed to %{prefix}/lib/python.../ instead of

Hi Nick, thanks for the answer.
Everything clear.
Just a further question.
Would a 0V-mean, 3.3V peak-to-peak sinusoid be correct as a reference
signal for the B100?

Josh,
I agree this would be a great feature.

Hi Vince,
Changing a little the topic, have you managed to run your SoftDVB code to
work on multiple USRPs in order to create a SFN DVB configuration?

Hi!
I have not managed to install what I wanted for my school project.
After gnuradio and uhd installation with the build_gnuradio script,
uhd_find_device found only usrp n200 but not usrp1...
I didn't have much time so I wouldn't touch anything in the first software. So
I would start writing t

Try:
uhd_usrp_probe --args "type=usrp1"
Then
uhd_usrp_probe
--args "addr=192.168.10.2"
That should (assuming you have networking
setup correctly) give you probe outputs from both your USRP1 and N200.

Looks like there may be a bug in the PYTHONPATH finder inside
build-gnuradio.
This has almost zero downstream consequences, since
it's merely offering a suggestion as to what to set your PYTHONPATH to
in your .bashrc. It doesn't automatically edit your .bashrc--that's up
to you.

Use a 5-10dBm reference with no DC component. This corres
Thanks Nick,
that's perfect.

Yes, there is a demo video on this from 2010 which you can view at my
youtube channel http://www.youtube.com/user/wwvince1
It's called Soft-SFN.

Hi Tom,
Thanks for the reply.
In the ofdm_sync_pn.py, I see that a matched filter is used, after the
timing metric is obtained based on the correlation of the two halves of the
preamble. I understand this matched filter is trying to find the end of the
plateau of the metric and get the smooth peak
Hi! Now it works! Thank you so much!

hi all,
I have made a simple program for sine transmission which is just a

with the help of side A of usrp1, but when i want to transmit it by
side B, it doesnt give any error but it doesnt transmit either...
My code is given as:
