Hi, I haven't run the bbn-code with gnuradio 3.6 but I did with 3.3. The
omnitreads aren't used anymore so try to include pthread instead. I believe it
will be possible to get it running.

Hi Martin and Andre,
We haven't got all the traveling plans yet, but me and Patrik are planning to
arrive at Karlsruhe the day before. It sounds really nice to meet for a

Hello,
We have been seeing a similar problem when we tried to change a top block by
stopping it and then creating a new top block.
First it looked like the problem was related to the synchronization of uhd

Hi,
I'm trying to build gnuradio with uhd on my system with Ubuntu 10.4. When

Hi!
What does the LEDs indicate when running USRP2 with UHD?
I understand some information about whether rx or tx are running is presented
on the LEDs, but I cannot find any information on which ones that is and what
the other four LEDs are indicating?
Best regards
Ulrika

Yes, if I remember it right the executor only checks a source for output space
and then calls work. If the work function doesn't produce any output it's
"broken" according to the executor code.

Hi,
What do we see in your example? Have you divided the clock by 10?
Is the output stable or are the edges jittering anything?
When I look at our clock outputs (in a very quick measurement) they are all
approximately in phase but the edges are jittering quite a bit, and I would

Hi,
I wonder how the timestamps are being generated for each ethernet-packet sent
from the USRP2 to the host? My initial idea about how it works was that
timestamps are generated at 100MHz (same as the samples) and then the timestamp

As far as the usrp->gnuradio block goes - the frame to stream 'conversion'
happens in the usrp (or usrp2) source block (and on the tx side that similarly
to extract messages from the queue. Take a look
in the bbn_80211b_pkt.py and I think you will see how the message queues are

We have encountered the same phenomena. The spikes at the carrier frequency
