Thanks for reply.
My plan is to extend the usrp_spectrum_sense.py: grab its output data and
let a py script find the best available frequency in the data; then put this
frequency into the usrp2_source block of file transmitter. In such case, my
py script would contain two top_block and the second

The problem is that it cant compute the mux when mixing real and complex
input sources. Its a known

Hello ALL!
I setup a fresh install of Ubuntu 9.04 on a very old Toughbook 512MB
RAM, Intel Pentium M 1.6GHz, 80GB HDD. My hardware is an USRP1 with a

I downloaded and ran the build-gnuradio script with the proper
security permissions (sudo access) on my /home/user directory.

That's a pretty aggressive goal, to hit 5W over the USRP BW. To get
reasonable linearity, you're probably looking at something that draws
25W of DC power. An external Amp is probably off the shelf. For
example, Minicircuits has a TIA-1000 that does 4+ watts out from 100
to 1000 MHz for $2000. You'
Does XCVR2450 and RFX2400 have software controllable channel filter as in
DBSRX2 ?

Hi, I am trying to communicate two usrps. In side A, i used Flex 1800 cards and
in side B LFTX-LFRX cards. I connected side A with antennas and side B with
