Hi all,
Any recommendation for a rechargeable battery (set) that can be used instead
of the power adapter for USRP and USRP2 radios? We would like to perform
some mobility experiments with the radios attached to laptop hosts and are
in need of moving the units from power outlets. Thanks.

Hi!
I searched the mailing-list for the Reed-Solomon coding in GNURadio and reached
some conclusions
1, if we wanna call RS in Python, we need to create our own C++ signal
processing block using the traditional C code in Reed-Solomon folder. After
that, we can call RS in Python.
2, we can mod
Hi all,
I tried to run tunnel.py with usrp+xcvr2450. However, there were problems
with the mode switching between tx and rx. The gnuradio trunk version is
Rev. 10798. Specifically, I have two usrps and some xcvr2450 and 2400
daughter boards.
First, I ran tunnel.py with two 2400 dbs, everythi

1) When I run my scripts I sometimes get "uOuOuO" message. I read in

archives that I need to increase the decimation rate but I have

set it to the maximum limit of 256. What should I do? Also, why do I

Hi,
We can output the data to a sink file, from which we load the data using
Matlab. Then we use scatterplot.
Thanks!

Hi, B
OK, that makes sense. I was assuming you meant receiver IP3, but when
you labeled something as OIP3, it made me think you meant the TX.
Typically, for a device like an amplifier or mixer, the manufacturer
will quote it in either IIP3 or OIP3, depending on which sounds better
:) Amplifiers
Seems like it cannot find gnuradio. Are you sure you installed gnuradio
correctly. Did you test the examples in gnuradio to see if the installation
went right? Look into /usr/local/share/gnuradio/examples directory. If your
installtion is correct then I suggest you check the ${prefix} in the
config
Hi, Yufeng
I am sorry for late reply. Unfortunately, I have not found it yet.
Thanks!

Hi, Paco
Actually, I got the similar result as you did. I think there was something
wrong in the mpsk_receiver block. I am checking it. Thanks!

The IP3 of the receiver. Sorry, I should have mentioned earlier.
