I did the following experiment:
I connected a square-wave to one of the J101 pins on the RFX1800 on two
USRPs. Then the two PCs poll

You are probably missing a lot of software dependencies for gnuradio.
From this page http://gnuradio.org/trac/wiki/UbuntuInstall find the

Then you can ./configure, make, and sudo make i
Hi all
(using Ubuntu 9.04)
I am still having problems trying to get gnu radio and grc to run but I
found what the problem is but can't figured out how to solve it. I tried to
reinstall everything. When I "./configure" , I get the following message at
the end.

It totally depends on where you implement the latency sensitive components. I
believe the best USB can do is a minimum of 100us, and that probably the
theoretical minimum. If you need 80-120 us latency, you will definitely need
to move the latency sensitive components to the FPGA.
Here are a
I tried to use the usrp for implementing rfid protocols, however the USB
latency is causing a bottleneck and I cannot generate and send the reply
packet before the timeout(I need to send the reply within 80-120 us).

Hi All,
I am looking for making a SDR. The source is IF at 1.44 MHz & 10 MHz with 50
KHz BW. Can anyone suggest a suitable low cost AD card which can be used to
sub sample the IF and further procees using GNU radio.
Thanx in advance.
