Thanks Eric,
I am using GNU Radio git depository installed a month ago.
tried on Cygwin 1.7.5+WinXP and OSX 10.6.3+Macbook, both behaved the same.
I'll try ubuntu tomorrow when I have access to another PC.
Ctrl+C exits the program but not caught by except.

Hi,
I have a Xilinx Spartan-3AN FPGA starter kit and I would like to
interface it with a BasicRX.
It has a
- 2 channel SPI-based ADC with programmable gain,
- 4 channel SPI-based DAC
Page 75 of the user manual describes the Analog capture circuit -

hello everyone !
i'm testing the benchmark_ofdm modules.i'm using rfx2400 db ,so i set rx and tx
frequency to 2.45G and
in transmitting side i set "--tx-amplitude=1 -s 32" .but i got the
following results,it seems that i have lost most of the packets,why?
ok: True pktno: 1840 n_

Guys,
I'm working on the same thing, I'm trying to receive something with OFDM
example, USRP2 and XCVR boards. But it doesn't work. The transmitter is
sending and the rx signal is crystal clear with spectrum analyzer but no
packet is caught.
Could anyone of you send me the command you're using at
Hi
I have some questions and observation on OFDM based transceiver.
I adopted the modified code provided by Veljko Pejovic (link:
www.cs.ucsb.edu/~veljko/downloads/ofdm_example.tar.gz). After trying
different combinations of parameters, I managed to get benchmark to work
with most package receive
hi all
what do you mean by Quadrature Rate and Audio Decimation in WBFM Receive
block in GRC?
and Channel Rate and Audio Decimation in FM Demod block?
I have captured wireless microphone signals using the following flow graph

What version of GNU Radio?
What OS, distribution, version?
(We fixed bugs in this area about a year ago...)

First let me say kudos to Josh Blum for a spectacular program, GRC. I
wasn't quite sure what it was and now see the value of it. No Josh, I
will not tell you what version I am running, but suffice it to say that
your program created a program running in a WBX, installed in a USRP2,
tied to eth1 (

Hello everyone,
after a long period of time I digged out my USRP1 again. What I want to
do with it is some testing in the field of HAM Radio. After some
research I came across the "Software Defined Radio Transceiver" project
[1]. I downloaded Ubuntu 9.04 (Jaunty) which seems to be supported here

Basically, I want to catch Ctrl+C after top_block.run()
For example
try:
my_top_block().run()
except KeyboardInterrupt:
print "Ctrl+C has been pressed. Exiting."
However, when Ctrl+C is pressed, the program exits straight away without
executing the print function.

Thanks for your reply..
Then what will be the data rate across USB2.0?.
Normally in USRP documentation they have given that the samples were
transfered in IQIQIQIQ fashion and each complex sample is a combination of
two 16-bit integers,so 4 bytes per each complex sample ,hence the maximum
data r
