Hi All,
I spent some time looking at the D-Star spec, which is supposedly
"open". Unfortunately, the published DOC (yes, singular) out there
are far from complete. Fortunately, Moe, Pieter and Robin did some
work analyzing D-Star and posted their results...
Doing D-Star with the USRP looks easi

Hello,
After looking at this document it appears that writing a APCO P25 CAI decoder
is a good way to learn error correcting codes because it uses many varieties of
different types.

Hi I'm trying to troubleshoot a piece of code that was handed to me.? The basic
application uses GNU radio and a USRP in transmitting digital signals and the
application uses the following file provided in GNU radio "benchmark_rx.py"
which can be found in the following directory

Here's another data point. I am using OS X 10.4.10 on a PPC Mac with Python 2.3.5, the one that
comes with OS X 10.4. I have built GNU Radio from trunk recently with no problems.
In order to avoid difficulties I have heard about on this list and elsewhere, I have not installed another
Python.

While some custom descriptions are necessary, it would be nice to be

Thank you very much!

Dear sir:
It is work!! Thank you very much.
But, why I can't see graph?
I have installed GNU Radio Companion, is it run on GRC?

Could be a number of problems:
+ The module "mc4020" is wasn't compiled / installed in the first place;
How could I install it?(My system is Ubnutu7.10, and I am step by step see
this page http://www.gnuradio.org/trac/wiki/UbuntuInstall)
+ PYTHONPATH isn't correct to find it;
I am sure I can run

What was the lowest bitrate
speex is nice. I've used it as well as the AMBE2000/2020. I wasn't in love
with the AMBE. We ended up doing lots of hacking to make the DVSI AMBE

Qi - It looks like you're mixing Python 2.3 and 2.4. That's not wise,
since there have been significant differences between decimal releases
of Python. Also, it's possible that Python 2.3 is too old. I think
Python 2.5 is recommended, but 2.4 works for the most part. I would
