Hi List,
I am trying to write some C++ blocks that makes calculations over 2048
point frames.
For ex. i need to take the 2048 point fft of the frame(contains 2048
points) and also
i need the index of these points, i mean where the center frequency is
(at which point).
Or i need to make calculation
Tom,
let me know when you have applied it.

Hey Guys,
we have two complete new Gnu Radio installations. The first Gnu Radio
installation we've installed on the 25th of February works properly. On the
4th of March we started the installation of the second Station but it will
not work.

Hi, i'm trying to connect the USRP2 by the Ethernet port. It seems as if the
port doesn't work.
The firmware is properly loaded (D and F lights are on) and the network is
properly configurated, but when i try to sniff the USRP2 ethernet port, no data
is generated/received. And no light upon the
Do you have a 1000Mb/s port on your pc. USRP2 works only with a 1000Mb/s.

So I checked all the pins in this daughtercard and they all look fine.
Could it be anything else?
Thanks any help,

Fine, it worked!!!
now I'll give it time to test around, and possibly report any instability.
Thanks again.

Hi Devin,
You might have tried this already but here it goes : when i first got my WBX
board, I had a similar problem - TX works but not RX. The daughterboard seemed
to be securely attached (i had used only 2 screws). When i put in all 4 screws,
then both TX and RX began working.

Best guess, the uhd installation is out of date with the gr-uhd
component you are trying to build. Can you verify that?

think of whatever is AFTER the trellis encoder and BEFORE the viterbi
decoder as an equivalent channel.
What is the equivalent channel in your case?
What is its input alphabet? what is its output alphabet?
From your description, it seems that the input alphabet is the same as

Hi, mr. Josh,
I have installed that USB driver before. When I connect USRP1 to the PC and
power it up I get in Device Manager a device called "libusb (WinUSB) devices"
in
location: "Location 0 (USB Device)", so driver is installed and it says "This
device is working properly.".
OK, I st
What is the subdevice spec (Mb0: subdevice_spec) for a USRP:UHD source?
I tried A:1 (to select RX2 on slot A, as provided at
http://www.ettus.com/uhd_docs/manual/html/usrp1.html) but it does not work and
gave an error.
Best regards,
-Vijay

Hi Josh,
If I am using a WBX board, what would be the setting for selection RX2 on slot
A?
And what would be the setting for RX/TX on slot A?
Best regards,

UHD is the way of all things Ettus going forward. If you don't have

I would like to know if there is a way to generate multiple windows using GRC.
Eg each window could contain an fft plot.
Combining more than 1 fft/scope plot on a single window does not quite work out
(the second window gets clipped with both manual and automated settings for
grid positions).

i'm working with USRP1 and i want to use only one transmitter ( 2 duc )
and one receiver ( 2 ddc ) and delete the other modules to free some area on

could i do so ? and can i fit a FFT with 375-point in the freed ar

No, but there is a tab widget called notebook (for wx gui).
FYI, If you use the qtgui sink, then the sink is automatically
You're right my suggestion won't work since the demodulation blocks
output bits, and the viterbi_combined block expects complex symbols.
I'll try again.
How about something like the dbpsk block

It's known that the channel band width is 200KHz
When looking into airprobe, gsm_receiver.py
