Hi all,
The problem is like this,
The two USRP1s will send the same number of bits, and then I want to
synchronize them in an easy way. Both of them trigger the TX signals at
the same time. The requirement of synchronization is not strict and
there can be a few disorder samples between them. And
Thanks tachwali ... it works out and very much thankful to you all ...

Hello list,
New code has been pushed to master and new images have been uploaded.
This effects USRP2, USRP-N210, and USRP-E100.
http://www.ettus.com/downloads/uhd_images/UHD-images-most-recent/
E100 Users: expect a follow-up announcement for an updated kernel and
instructions.

Hello Guys,
Was anyone able to get Probe MPSK SNR block to work under GRC environment. I
could not get it to work. I used it with the function probe and used the
"noise_variance" method and the appropriate block ID values but the problem is
that upon running, it is not updating the value inside
I am curious if anything like this is available for the USRP version 1,
for anyone who might know.
As a random side note, it would be interesting if future versions of the
USRP contained off-board RAM chips for data buffering for just this
purpose. The reason I suggest this is for making the

I posted this to the USRP users list since we're not using GNU Radio proper for
this project, but Devin's questions about spectrum sensing make me think it
could be useful for GNU USRP users, too. Although we did this on the N210, it
might be possible to do something similar on the USRP2.
We've

I forgot to mention I'm using the WBX, not the TVRX. I'm using the UHD as
well.
