Hi all,
I am stuck on this problem for long. So,any help will be appreciated.

prerequisites including wxWidgets and py26-wxpython using MacPorts. However,

Hey all,
I am still checking out whether my USRP is working correctly in both
transmit and receive modes or not.
The problem is sometimes when i run the transmitter or receiver codes, the
USRP fails to set the RF frequency of my transceivers, and at other times it
works. I don't know what is caus

Hey all,
I have already installed Gnu radio before. But, because I am new to gnu
radio, I have not installed all the important components.
Now, i want to install GRC. I see that there is GRC folder in the gnu radio
folder that I downloaded using:
$ svn co http://gnuradio.org/svn/gnuradio/branche

There is no distinict pattern. How I am working it out currently is;
when the error apears, I turn the USRP off and turn it on again. In that
case, it works mostly. But, I was

Hey all,
May be my question could be out of topic as it is can be a hardware
problem, so excuses.
The Thing isI am using USRP with XCVR2450 Tranciever to develop a
doppler radar(in duplex mode).
So, I was checking out my devices.
When I use USRP_fft.py just to see the environment signals
ause it doesn't do that -- it does not do FDD. The RFX-series will work
