Hello all,
Can I still call set_auto_tr to enable auto switch Rx and Tx with
xcvr2450+usrp2? It seems like the set_auto_tr is no longer available. Is there
any alternative API for same function? Without calling set_auto_tr,
USRP2+xcvr2450 can receive normally, however, no luck for transmission.
Hi All,
I am working on the OFDM project. When I run sudo
./benchmark_ofdm_rx_video.py -f 450M -R A -v -d 32 --fft-length 128
--occupied-tones 100 --cp-length 32, I want to terminate the process if the
pktno>100. I tried:
def main():
def rx_callback(ok, payload):
global

Johnathan,
Thank you for the image/firmware update.
I wonder where I can find a change notes for these new release.

The USRP C++ example program uses this code to move USRP USB data into a buffer:
urx->read(&buf, bufsize, &overrun);
If this line is called many times in a short period of time will the buffer
have some of the data leftover from previous read(s)? Can I assume that the OS
will not return

It does seem like, from the error message, gnuradio-core is missing. But
why?
The output from running configure is very long, the last bit summarizing
what happened (below) says gnuradio-core was successfully configured,
but some other
stuff wasn't. Then make ran without generating an error. W

There is a 3.2rc0 tarball on the website. 3.2rc1 is coming this weekend.

Hi,
I'm a newbie and I'm trying to test my new hardware (USRP2).
Can I listen a FM station with DBSRX or RFX900 or RFX2400??
My hardware:
- USRP2:
SW - txrx-edk10.1-r10524.bin
FPGA - u2_rev3_ise10.1sp3_r10524.bin
My system:
- Ubuntu 8.10
Hi,
I have been trying to use USRP2 as a receiver and USRP1 as a transmitter.
The benchmark_tx.py file is working well for USRP1 but I did some
modifications to benchmark_rx.py so that it can work on USRP2. But it didnt
worked out. Can anyone help me with this modifcations so that I can
establish
Just an FYI that the link

I'm working with a customized flex400 board which has been modified to
work in the VHF (140-160MHz) band. To do this, we ended up changing out
the VCO from the ADF4360-7 to a ADF4360-8. However, this required
modification to the db_flexrf.py to account for the differences in the

Many don't. Subversion uses portions of the HTTP spec that aren't

Python doesn't know about the gnu radio libraries, did you do a make
install? (as root)

I do not understand why you have the problem? Do you have the latest
gnuradio trunk installed? http://gnuradio.org/svn/gnuradio/trunk
I have the SVN Version 2009-Jan-28.
It was this changeset on jan 28th http://gnuradio.org/trac/changeset/10327
Make sure the files are installed.
good luck

Any news on GnuRadio 3.2?
Also, any chance you could update
http://gnuradio.org/doc/doxygen/index.html? (It's still at 3.0svn,

Also, is there any way to add search to the doxygen interface?
