Hello all, I’ve got a GNURadio install on two laptops, both of which
have
version 3.3.0 on them. They are both Dell Latitudes E5500 with Ubuntu
9.10
x86 on them. I have two USRP2s with the correct firmware installed on
the SD
cards to operate the WBX daughter card (txrx_wbx_raw_eth_20100608.bin).
I
have been trying to run the out-of-the-box benchmark_tx/rx.py scripts to
just get correct packet transfer between the two. At first I found that
having the radios too close together was causing the issue but even
after
moving them apart it still has an unacceptable BER. I followed the
install
instructions as follows:
- Install dependencies in the blip of code given for the “sudo apt-get
…”
command for Ubuntu 9.10. - Download gnuradio-3.3.0, unpack.
- cd; ./configure; make; sudo make install; sudo ldconfig;
On a another note using a separate computer, a Sony Vaio with GNURadio
3.3.0
installed on Ubuntu 10.04 x86_64 seems to transmit to either of the Dell
laptops just fine using the benchmark scripts with no errors at all.
The output on the receive is as follows (Ctrl+c’ed because nothing else
was
transmitting):
~/Desktop/gnuradio-3.2.2/gnuradio-examples/python/digital: sudo
./benchmark_rx.py -f 910M

^C~/Desktop/gnuradio-3.2.2/gnuradio-examples/python/digital:
The output on the transmit (which seems to runs all at once instead of
dot
by dot as the Vaio does) is as follows:
~/Desktop/gnuradio-3.2.2/gnuradio-examples/python/digital: sudo
./benchmark_tx.py -f 910M

Does anyone have any suggestions, comments, etc,? Thanks.
