Hi, Johnathan, John, Matt and Josh
Thank you all for the help! The problem was solved!:)
When I am using the SD card via a USB adapter, it shows the name dev/sd1.
By using this name, it gives me the same results as before.
However, the USRP works well by using the name mmcblk0 . :)

Nothing forces you to interact with other ham radio operators. You can
happily work in isolation communicating among your own stations if you
wish.
Unless you need to do frequency coordination, which you usually do.
Then you have to deal with the oldest, gnarliest hams around, the ones

My project changed but at the end

Hello,
I'm considering using GNU radio for an upcoming elective course I'll be
offering in software defined radio. I'm looking for suggestions for textbooks,
course material, etc. I'd also be interested in hearing about anyone experience
good or bad who may have done this before.
thanks,

Hi All,
I wanted to use some of the communication related signal processing
functions in gnuradio. Has anyone done something on these lines before?
Please let me know.
Thank you!

Hi all,
I have a problem with the USRP2 board when working with the DBSRX
daughter board. I am using the
usrp2_rx_cfile.py file to collect some data with center frequency
around 1.5GHz which is within the range of this daughter board, but it
fails. The USRP2 works with the RFX 1800 board with
The exact same code works on two other machines, both running OSX 10.5. The
sink is a locally created modules, so it is entirely possible that there is
something missing in the instantiation that is being caught on only on my
machine and not at others (for what reason I cannot fathom).

Hey Per,
Thanks for replying! I wanted to start by incorporating channel models
(channel.h if you are familiar with IT++) and was wondering if just writing
a wrapper function in swig would do the necessary work for us or we have to
make some specific changes to incorporate those codes in gnuradio
Hi Johnathan,
Have you had any luck with this issue? The same is happening on my FLEX2400
with USRP2.
Here is the full error message:

Hi,
I tried to use trellis_encoder from trellis package to perform
convolution coding before sending the message to the OFDM modulator.
However, ofdm_mod has zero input signature, and relies on send_pkt()
which calls ofdm_packet_utils.make_packet() and then puts the message
in the queue at
