Hi, can u help me?
I want to know which are the step and the file to recompile after a changing

I have to modify a .cc code to use this modification in a py script as a new

Thanks,
HI Domenico,
You can 'make'(from terminal) the folder in which you have modified .cc and
.py files.
It should work fine if there are not errors in your modifications..

I am trying to implement the Alamouti 2x1 scheme but i have some problems. I
create 2 channel in order to use 2 antennas but one of the channel has less
power than the other and i am thinking that the signal is not being transmited
by both antennas . Does it matter the distance between the 2
I'm trying to simultaneously send and receive a sine signal with the
USRP2 with a RFX900 Daughterboard. My setting is:
- An arbritary signal generator sends a sinus signal to RX2
- The USRP2 sends a sine signal through TX/RX to an external Scope
- The sampling rate is 1e6
- Interpolation at the

I'm deeply sorry but i have to disturb u again...
I changed the file db_dbsrx.c in /gnuradio/usrp2/firmaware/lib to
insert a new method and c++ compiling at command window is not my best

Hi all,
How to set the bitrate and the DAC output amplitude, if only need to generate
baseband signal as a 25kHz square wave and tune to RF?
Thank you so much

Hello,
I understand that the new firmware supports full duplex for RX900.
Would anyone happen to know how I would augment my c++
code (similar to rx_streaming_samples.cc) so that I can select
antenna port RX2 for my reciever. I see how it is done in python,
but wondering how to do it in c++.

Hi all,
What is the gameplan for the new inband infrastructure? VRT now defines the
protocol/structure of the messages between the USRP and host... but what
about message passing at the host?
This is something I'm going to need in the near future, and if the price (a
very, very, solid plan) is
