Hi Rickard,
have you perused the mailing list archives? I remember a discussion about
this maybe two years ago.
IIRC, the bottom line was that no, gr_sounder is not really useful. In
particular, it has no means of synchronisation and therefore the result
is too noіsy to be useful.

Hello!
I am working with USRP2 under Ubuntu 10.10 with the GNU Radio driver.
I was successful adding some setting registers to the FPGA code and
configuring them with the poke32 method (class usrp2_source_32fc_sptr,
module usrp2). What I am not able to perform is a reading of this setting

Yes, I have read thoroughly every discussion there is in this list and
elsewhere.
It is true that there is no synchronization implemented resulting in that the
location of the CIR-peaks will not stay put within the PN-sequence period but
"rolls" (corresponding to the clock mismatch). However,

After quite a while away, I'm trying to get gnuradio, grc, and uhd
running on my Ubuntu 11.04 machine.
The .deb packages I grab via the Ubuntu software manager install fine,
but when I try to run grc I get a crash. I see that this has been
reported as a bug a month or so ago; the error I see

It is very hard to help you. You are basically saying "we did something
different and it doesn't work." You haven't posted code, you're using
an old version of GNU Radio, and not using the latest drivers (UHD).
This all makes it hard to help you.

It worked great. Sweet. One USRP device with 8 motherboards!
Is there a way to increase the number of input ports of WX Scope Sink
from 6 to 8. I think it is giving an error beyond 6 input ports because
of colors limitation.
One more thing: Is there a way to have variable filenames in GRC that

Your best bet is to build from source:

covers Ubuntu 11.04 quite well.

Hi,
Thank you for your attention.
We know that we are working with old versions and this is a problem. We've
had some previous modifications, and it seemed easier to keep working with
them instead of porting everything to the latest firmware/drivers.
Anyway, we will take a closer look into what

Hello,
What kind of error does the GRC give? Occurs the error while making the
GRC?Because I had an error while making the GRC and I worked around it.
I have downloaded the latest GNURadio from the site. Then I copied the files of
my own signalblocks from the old GNURadio to the new one.In the n
Hi John and Colby,
Thanks for the detailed and helpful replies about the sampling rates. Now, I
have another issue which is unclear to me. I am printing out "noutput_items"
for my custom block which come out to be either 1 or 2. As I mentioned before,
the custom block is intended to do sample b
