I replaced my WBX boards with rev 3 and it looks like its working now.
However, I would still like to be able to run the calibration routines on
the rev 2 versions. Are you guys going to support this?

Hello,
I was running the calibration routines for 3 USRP N210s and one 1 USRP
radio. I had them all connected at once to my computer and all of a sudden
it says Error: RX dboard has empty serial!
How do I know which board has an empty serial and how do I fix this?

Hello I am trying to synchronize two USRPs together using the MIMO cable.
I tried to set the clock and time source to the MIMO cable and it says that
this feature is not available in this version.
Is this true or am I missing something?
How do this?

Hello All,
I've been writing my own signal processing blocks and I noticed that
gnuradio only uses one of my cores.
I'm not sure if it is using just one core for my blocks or for all
processing.
Is gnuradio written to take advantage of multicore processing?
I have been writing my blocks in ge
I did, but it still picks the old version.
I also noticed it picks an version of python, instead of the one I manually
installed.
Is it possible that it picks the version that it first sees?

Hello,
I have two SWIG versions in my machine. I am using Centos 5.5. One is

Centos doesn't update their repositories on a regular basis, I had to

Hello,
Is there a way to decrease the A/D quantization error for low input signals?
I've been sending -50dBm to about -70 dBm sine waves to my USRP 1 radio and
the quantization noise is there.
Is there a way for me to reduce it effectively?
Thanks.

Yes with 40 dB attenuation.
Somehow I didn't see your post.

Any thoughts on this or comments?
Also can someone please show me how to open the file output of gr-sounder.py

Thanks!

Hello,
I'm trying to figure out how to measure the impulse response of a channel
its coefficients.
If you have any information on how to do that, please let me know.
Thank you.

I did fix it. I put self.result_data = self.dst.data() in the print_data
method and made the necessary changes and it worked.

Hello,
I tried to print what data gr_vector_sink_f contains in the following code:
#!/usr/bin/env python
import howto
from gnuradio import gr, gru
from gnuradio.gr import firdes
from optparse import OptionParser
from gnuradio import blks2
class howto_square (gr.top_block):

Yup this works.
That was pretty confusing.

Hey Guys,
I got this error when I tried to run grc:

The program 'grc' can be found in the following packages:

However, when I ran ./configure it states that it will make grc. I don't
