Salut!
I think our issues are related to the synchronizations parameters (Costa's
loop and MM). It seems that they must be chosen very carefully,
especially costas_alpha and gain_mu.
In order to choose them, I plugged a constellation sink into my modulator
using GRC. As the constellation sink is
Hi all;
Thanks to Mr. Balister I run USRP on BeagleBoard (
http://www.opensdr.com/node/17) . But it doesn't give any sound when I try
to listen FM radio. I think there is some mismatch in sampling rates or data
format. I read other mail list archives but they didn't solve my problem.

I've been working on redoing the digital modulations in the background
for a little while now, and I just merged in a branch with newer
features. So that I didn't interrupt the flow of anything, I just added
a version 2 for everything in the digital modulation path instead of
changing what was

Hi Eric,

Hi Eric,
Thank you I got it. I am also trying to study the c++ examples under
../gnuradio/usrp2/host/apps/... ( My objective is to write a channel
switching apps in C++). However, when I run ./rx_streaming_samples -f
2.45G, it doesn't output anything when I run ./tx_samples at the sender

Hello
Sorry if this is a duplicate.
I am using my digital scope to capture data and pipe it to a flat file where I
can look at it in LINUX (gdsh USB and perl)
I am attempting to decode 1090 MHz transponder signals.
I know what I am looking for. ( I do this for a job)
I am on the hunt for
Hi all,
Just looking through the WBX daughterboard code in the latest git repo
for adding support for the USRP2 (which can be found at
usrp2/firmware/lib/). I noticed that in adf4350.c, there is a #define
for INPUT_REF_FREQ that is defined as 50e6 (50 MHz), which is then
used in all of the
Andrew,
Eric Cottrell has written a complete Mode S receiver for gnuradio, using a USRP
with a DBS-RX daughterboard. I also use a 1090MHz SAW filter and an LNA in my
setup to get better results. Eric's software has not been ported to the current
gnuradio architecture and uses the older blks

Hi all,
I wrote two gnuradio AFC (Automatic Frequency Control) demos
This AFC technique can come in handy when your tuning is critical and
there is a frequency offset or doppler shift to be expected.
(Like when trying to receive NOAA weather satelites which can have a
substancial doppler shift.
Thanks Nick
I have some more questions if I may
1) What determines the bandwidth of the daughter boards for USRP ?
2) Where do you connect if you want to bypass the RF board and connect at
base band ?
3) Will I be able to achieve what I want to achieve on openSUSE linux ?
4) When you talk
