I'm new here, but I can already tell that GNU Radio is Really Cool Stuff. Thank
you for your great contributions, and I welcome our new overlord!

If the signals you want to receive are sufficiently close to each other,
you could tune the WBX in the middle and use two independent DDC to
receive two signals with one WBX ...
(I'm not mistaken ...)

Hi Jason,
First question what are you tring to do, receive or/and transmitt?
Second: Why is 4 (2TX x 2RX) antennas needed if I understood you correctly?
If you have two USRP(N)'s, I'd connect them to two different machines. You can
connect both USRP's to the same if you got a robust machine.

Jason and Marcus, thanks for your responses. I was afraid that this was the
case.
Is there a daughterboard out there (besides the BasicRX) that can support 4
antennas on a single USRP?
The other option that would work for me is connecting antenna 0 to WBX 0 and
connecting antennas 1-3 to WBX 1 t
I have a USRP and two WBX daughterboards. Is it possible to use 4
independent RX antennas (all tuned to the same frequency) with this
hardware setup?
Specifically, here's what I'm trying to achieve:
Antenna 0 -> Side A WBX, RX/TX port -> ADC0 -> DDC0I
Antenna 1 -> Side A WBX, RX2 port -> ADC1 -

Scott,
The WBX has only one (I/Q) receiver per daughterboard. The two

My guess is that the inner channel (ie the combination of OFDM
modulator/channel/OFDM demodulator) is producing big bursts of errors.
Essentially either the packet is correctly received or completely
erroneously received.
In that case the outer Convolutional code cannot do much; on the

Many thanks for your time Eric!
I have signed myself at many RF groups but I have not seen
yet "this quick help/suggestions" from any.
I bet (hope) you can not keep your fingers off?

As some of you know, I've been involved with GNU Radio for a long
time. The idea that became GNU Radio started as a conversation over
dinner in San Francisco with John Gilmore, something like 10 years
ago.
Interest and use of GNU Radio is currently at the highest level it's
ever been. I however,
Hi again,
We have written a small example that triggers this error (see the attached
files). From what we have figured out so far, the error arise from the result
of the p->wait_for_completion command in the transmit_cmd_and_wait function in
the usrp2_impl.cc

Hi,
Between wxWidgets-2.8 and wxWidgets-2.9, there are some breaking
changes with the way the OpenGL rendering contexts are handled. You can see the
difference in the samples/opengl/cube example in the wxWidgets-2.8.11 and
wxWidgets-2.9.2 svn repo.
I just have a quick quesion which is,
