Hello,
I would like access to the I and Q output data (12 bits each) from ADC U601
using the debug headers from two RFX2400 daughterboards and was wondering if
someone could assist my understanding and tell me if what I am doing is
right or wrong prior to my actually implementing this on the USRP

I have been running the usrp wfm stereo receiver for a few hours under
Feisty Field Rat from Ubuntu.
The memory percentage for the python is absolutely steady at 4.0%. The
same with the Xorg process (at 1.9%). It appears the memory leak has
been repaired.

We don't have many docs, but we do try to get the ones we have right ;)

YOU MEAN RTFM?
Well, that worked. EVERY step has to be done. I guess that is why
there is a manual.

I have two basic Tx daughterboards, so each one use different AD9862. I
have a question the 2 AD9862 they both get there clock in from the usrp
motherboard, and that is the same clock?
The AD9862s (which are on the motherboard) both get the same

Hello again,
Thanks for those that emailed me directly with my last request. I have
been able to get my transmit code to tune now, but it is still not working.
All I am trying to do is fm modulate a sine wave and transmit it at a
certain frequency. I have hooked up a vector signal analyzer and

I have run into my first Feisty Fawn Ubuntu update issue. usbview works
perfectly and reveals the USRP 2 as connected to my computer. But
running my favorite application that wishes to talk to the USRP seems to
have changed behavior with python 2.5. It claims it cannot find "USRP #0".

hey guys ,
i am doing a wimax module , the baseband is already implemented on DSP using
simulink and i am working on The RF stage on the usrp
but the problem is how can i interface both of them togther i have 2 ideas :

If you don't want to use assembly, you can use MMX and SSE intrisics
compiler support. These are C functions/macros to allow the use of SSE
instructions directly from C/C++. You can start with this introduction:
http://www.codeproject.com/cpp/sseintro.asp . For a reference, you can go on
MSDN webs

I've written a couple of blocks for GNU Radio, but am not satisfied

not easy. I know that
