I fetched the gnuradio code yesterday and installed it on Ubuntu 9.10.
It's the only gnuradio install.

Thanks for your response. I have
following queries on the sampling rates in USRP2.

I set the

I'm a new user of gnuradio.
I want to use this software to analyze a traffic on wifi channels.I have a

Is it possible that someone could confirm the problem?

It can only handle two channels, and it takes 78% of the CPU while doing
it, but it does work!
How about calculating a $ per sample number?

That's unfortunate. If the USRP stopped working entirely, the fuse

Hi all !
My superior asked me to figure out the meaning of each LED on the USRP2. Since
yesterday, I am looking for it, unsuccessfully. Most documents only say that if
the USRP2 is ok, all 6 LEDs will flash at startup and 2 will remain on (E and
F).
Does anyone know the meaning of each LED

Not quite. It means that the FPGA is interpolating and creating 6
samples on the DAC

I solved my configure problem. Now I am only getting make check error.
Here is what I get:

Hi
Have you solved your problem? because I'm facing the same problem.
I think in your code there are two mistakes:
1. the mux value should be set to 00230001 not 10321032.
2. may be you are missing :
self._rx_subdev = self._u.db(0) + self._u.db(1)
Anyway, I'm not sure. but because when i do :
