What is it about

Wolfgang Kaufmann wrote an impressive article and even a more impressive software for the hobby radio astronomers. I highly recommend checking out the article and play with the software as there are not so many radio astronomers among the community. His software is written in python with a very clean UI. It directly connects via the computer sound card and grabs the audio signal. I shortly describe here what to install on a Mac OS to get his software up and running.

Where to get it

The software can be downloaded at http://www.ars-electromagnetica.de/robs/download.html. Unfortunately it is not available on any online repo like github but the source code can be downloaded as a zip file.

Preparation

The PyAudio package needs some libraries and direct access to the os sound system. Therefore we need it install this audio package outside of python itself

brew install portaudio

The necessary python libs can be installed via pip. I recommend doing it in a virtual environment

mkdir ms
cd ms
virtualenv -p python3 .
. bin/activate 
pip install cycler matplotlib numpy PyAudio pyparsing \
            python-dateutil pytz scipy six tk-tools   \
            xlrd xlwt

That is all. After installing the python libs the program starts right away

python MeteorLogger_v1.21a.py
