hi ,
I am using Fedora Core 11 OS. I have succesfully executed
benchmark_tx.py, benchmark_rx.py files. But coming to TUNNEL.PY I am unable
to ping to the other computer. Self ping is working.
Please help me, ( I am a beginner)

In the binary floating point data,how many bits represent data and how many
bits represnt the right?

I use a file sink to received the result of Log Power FFT and it can be
excute successfully.
But the file which I saved is hard to read and understand.

I use a signal generater to transmit a signal, then I use USRP to received.
USRP include a
A few ways I can think of off-hand:
1) make a custom gr.hier_block2 in python, it can read from a message queue
2) use a file sink to dump the data from the log power fft to file,
post-process the file
3) you could use the variable sink in grc to write the fft vectors to a
variable called ff
Ok. I add a vector sink in GRC and to observe the data in that module.
But when I run GRC there is no result shown. I need to add some other block
to see or I need write some code like "prinf" in Python?

all blocks that have:
1) a float input/sink port
2) a vector length set to fft_size

Dear all,
I am having a problem when I try to run the dial_tone.py example. I get the
message: "ImportError: Unable to locate an audio module".
I already tried to install gr-audio-alsa and gr-audio-oss modules, but is
said that they can be accessed by gnuradio module. It might be a gnuradio

Hi All,
I am implementing a OFDM tranceiver. I am following the benchmark.py and
tunnel.py for achieving it. I am facing the following problems while
performing receive--> transmit--> receive:
1.It receives on the startup of the code.
2.It transmits and then it does not receive at all.
I hav
I am planning to implement a wideband reciever (upto 800 MHz) using Basic
Tx/Rx and TV Rx card. Pls provide following information:
(a) Souce of good quality RF front ends/ LNAs for use with Basic Rx & TV Rx
daughterboards.
(b) What is the receiver sensitivity of TV Rx Card
Also, are there any pla
Dear All,
Our research project requires the use of sub-GHz daughterboards in the
USRP. We have identified the TVRX receiver board and RFX400
transceiver (is there any other option that supports the range that is
supported by the TVRX on TX side?). However, our confusion is on the
antenna to be use
