Well, in that case, probably your "UDEV" rules create the device world
read/write.
Check /etc/udev/rules.d/*usrp.rules

After successfully installed uhd and gnuradio from the next branch on
F13 i run a simple gnuradio-companion test with a flex 1800 as the
source and an FFT sink.
It seems that when i use a uhd source my signal is ~ 80dB lower than
when using a USRP source. What is the explanation of this?

Yes, I was sending all 1000 for each sample. I completely forgot that
the DC component may be wiped. However, I also tried sending
gaussian noise (mu=0, sig=1)*100 and still didnt see the signal.
If you're sending gaussian noise, that'll be really hard to see as well,
since it won't be diffe

Im going to take a closer look at the interface to determine which
daughterboard and output is used
Hi Patrick,
First, thanks for the reply!

I'll try to do that, I've seen through a FFT after the

I have on USRP and I'm simultaneously sending an receiving data from it
using the UHD interface. Im trying to determine if I am sending my samples
at all. I am sending all 100's using COMPLEX_FLOAT32 interface. I have a
basixRX and basicTX boards. Both are hooked up on the A side of the USRP.

Hi all,
I implemented SPAN code in usrp-1, gnuradio -3.3.0 .. (downloaded SPAN code
and modified to work with 3.3.0 version)
I changed my lap's wifi datarate of 1Mbps using iwconfig command and i
received Beacon frame..i got this correctly.
Then, i connect another lap to ad-hoc network and used
Hello everyone,
As Euripedes Rocha told few days ago in the email "Who actually *does* use
GNU Radio?", we're starting to use it here, but we do not currently have
daughterboards to use with USRP2.
Due to this, specially in my case, I'm building some simple diagrams using
GRC, and one of them is
