Hi Pablo -
Have you tried tuning the audio rate a bit? When you see the 'aU's, do you
also hear distortion in the audio?
Cheers,

Tom,
Interestingly, when I was retesting the cmake output for you, I built it
manually after that and it worked this time - no ice complaints. So, the
problem seems likely to be somehow brought out when pybombs does the build
(maybe passing options that I did not when compiling manually).

The 'Stream To Vector' block takes a stream of samples and makes a vector
stream out of them. This vector stream is just the samples from the stream
put into parallel so that for each sample you are actually sending the
vector length per second as the sample rate.

Hello,
Ive heard about costas loop to obtain the carrier of a PSK signal. But I
dont know how it is implemented the carrier recovery in the hrpt example of
gr-noaa in order to demodulate the BPSK signal. I would appreciate some help
with this topic.
Regards,
Pablo.

Hi guys,
While i was trying to figure out what the stream to vector block does,I
understood that if I choose for example nitems=1024 and vector length=1,I
get in the output 1024 vectors of 1 item each.And when I was reading about
it
on this web page (
http://gnuradio.org/redmine/projects/gnuradio/
I was unable to get GRC to perform acceptably under VMWare on a very up to
date system. The USB support is very slow.

Hi,
I built a FM receiver working with a LiveUSB and a USRPB100 device. It
worked fine, but when I installed Ubuntu and GNURadio in a virtual machine,
the audio is distorted. The console types aU letters. But I generate a wav
file and the quality is good, the problem is with the audio sink.

Wait, why do you have a lib64 on an Ubuntu machine? But, we do check in
lib64, so that shouldn't be the probl
These 'cannot open shared object file' errors are usually solved for me by
running 'sudo ldconfig'.
Pybombs should not be run as root as everything gets installed to the
target directory.
You need to run './pybombs env' and append the line about 'source ...'
to your home directory's '.bashrc'
