Hi,
I did try and made a GRC example of using a USRP Source and a fft sink,
scope sink, and a file sink to test out the idea.
When looking at the scope sink, the data is about +/- 2x10^-4. I changed
the gain of the USRP source block to 20 dB. But nothing happened to the
signal amplitude. How is t
Hi Josh,
I've attached the xml file for "my_block.xml". I don't have a .i file (like
"my_block.i"), because it is using the "extras_blobs.i" file. I've attached
for you extras_blob.i and I added some lines to that .i file in order to
include "my_block".
All the example is based on blob to stream

Hi,
I've just finished my block that generates PSDUs and then, it transmits
downstream subscribers using message passing mechanism. I am using as a
sink "Extras: Blob to Socket", but when I run my flowgraph in GNU Radio

USRP1 may have 2 transmitter and 2 receiver frontends.
You may transmit from either frontend and receive from either frontend.
Any combination should be OK.

Hello community,
I am trying to use the uhd_rx_cfile command to capture some rx samples in
the hope of recovering what I see as streaming samples in the uhd_fft Scope
mode display. Since I am really new to GR+USRP, I have a couple of
difficulties:
1. The uhd_rx_cfile command help menu does not pr
Hello,
I have read in your frequently ask questions that we may record data from two
daughter boards in one USRP. But i have the same question but in different way.
Can we use one daughter card as sender and the other as receiver, rather using
two USRP for this purpose.
Best Regards.

I contacted Ettus Tech support. They said that basicRx card samples
at higher Nyquist region. So, it requires external RF gain and filtering
component.
Can someone suggest such a RF component which I can buy off-the-shelf
which can work with basicRx card?
Thanks.

Can i use my own system as both a source as well as sink to test the same ?
It is because i do not have two terminals at my disposal for the time being.
I am proposing the following model :

I am now doing consume_each(noutput_items) but my problem is not solved yet. I

Hi All,
I have USRP N210 but I cannot probe it using usrp2_probe.
when I am trying capture packet, it is said "No USRPs found on interface

Dear Tom,
I backtraced this call and there is no implementation of gnuradio
preference file. When it is called the architecture, it returns
gr_prefs::singleton()->get_string("audio", "audio_module", "auto");
Thus, get_string is implemented as this:
