Well, no. Once you ship a binary to even a single person (outside
your company), that person is free under the GPL license to make

Hi everybody,
just a simple question:
does the RFX900 provide 200mW just out of the box? Do I have to take care of
something in particular in order to obtain them?
Actually, what are the appropriate gain values that I should pass to
subdev.set_gain() n order to maximize correctly the output power?
I am trying to extract data from a Turbo Code signal. My block’s input is the

in order to drop FEC bytes and send only useful data on the ouput. The

I have been getting a lot of 'iU' outputs when I run my scripts, and I
found in the FAQ (here: http://gnuradio.org/trac/wiki/UsrpFAQ/Gen)
that:
"u" = USRP
"a" = audio (sound card)
"O" = overrun (PC not keeping up with received data from usrp or audio card)
"U" = underrun (PC not pr
John,
I understand that if you just provide the binaries to a customer, you must give
them a means to get the source code, and if they choose to distribute that
binary to others, they'll just pass on that original offer and hence you're on
the hook for providing anyone with source thereafter.
Looks like you're using Mac OS X ;) If you're not, then please let
the list know what OS you're using & ignore the rest of this message.
That "iU' should get fixed, since it's not in-line with that the FAQ
states those "codes" should be. It signifies that there is a read
overflow on the U
Hello Guys,
I'm a newbie in gnu radio. I started playing with it at the end of last month.
I'm wondering if we could send out or receive IP/Ethernet packets (by
some user space applications), and then send them out or receive them
though wireless media with tun/tap drivers. I'm not sure how the

Your question doesn't make sense to me. If your clients pay you to develop
source code that derives from, or
partially incorporates, GPL licensed code then they own the developed source,
not you. They are responsible for
license issues with the newly developed code.

Hi Kylie,
This has also been proposed by Minn et. al in their paper "On timing
offset estimation for OFDM systems". They showed that this method also
improves the variance of the estimator.
The modification is quite simple:
R(d) = 0.5 * sum over full window |r(d+m)|^2.
I think, normally the

They might "own" it, but since using GPL requires the company who paid me to
provide the
Oh, I forgot to mention that both the attached plots in my previous mail

Thanks for the pointer to the literature!

Hi,
I'm a gnu radio newbie. Can anyone tell me how to see what kind of mac/phy

there any documentation about this?
Thanks.

Please, I want to know about some details of blocks at
MAC and PHY layer. E.g., what kind of MAC modules or blocks that gnu
radio can provide us? I've read the tutorial here
http://www.nd.edu/~jnl/sdr/docs/tutorials/9.html#tthFtNtAAB but I can
not find what I want.
Do you guys know whether there
