Josh,
Could you make example application for transmission as well. I think it
would help greatly.

Quoting Josh Blum :
gnuradio does not offer any kind of sample decoration. So, the
metadata is present in the simple uhd source block, and dropped on
its way out of the block.

I laugh heartily at your puny FFTs of only 4096 points :-)
I regularly do FFTs with 1Hz resolution over bandwidths o

I would just store the data using gr.file_sink and format it accordingly by
writing a routine. But if you want to build a block that stores the data in
the format you require then you can build a block yourself and add it to the
grc. To add it to grc you can look at this page,

You probably need to load the SD card with the txrx_wbx.bin firmware:

Hello everyone,
I just got the USRP2+WBX recently. And I used the famous "usrp2_fft.py" as a
starting point.
The problem I met is that the curve plotted by the usrp2_fft.py seemed to be
abnormal. Sometimes, the amplitude of the curve was around -150 dB, and
sometimes it went below -400 dB.

I know that some UHD functionality requires at least boost-1.38, but I'm
not sure about the trunk in the
current state.
theres a minimum of boost 3.6 for the uhd FWIW -Josh

You would need to make some kind of c++ app in gnuradio or maybe

I have been working with the uhd version of gnuradio and have attached a

This is mostly due to my limited C++ coding skills. Has anyone

WBX support for the USRP1 can be found in the current gnuradio git master.

Hi, all
My system is Ubuntu 9.04. I use git and install gnuradio from source. After
install all the package, I run
$ ./bootstrap
$ ./configure
$ make
However, there is error happens
audio_portaudio_source.cc:91: error: no matching function for call to
‘boost::unique_lock::unique_lock()’
I was going to make a more formal announcement, but here it goes:
I pushed WBX support to the UHD master just now. Instructions here:

When in the open state, the valve is internally 2 blocks. A null sink,
and a null source + head(0) The valve will "eat" all incoming samples
without back-pressure. If you have no throttling, the means 100% CPU
utilization. I would put a throttle before the valve block.

Hi all,
in order to use the new WBX daughterboards, do I have to get the new

How can I get the receive signal strength (db) from usrp_wfm_rcv.py or

Or have other way can do?
