One of the great advantages of software defined radio receivers is that tuning receiver settings is a matter of adjusting software parameters. Gqrx is no different here and has optimal settings built in for weather satellite reception. This tutorial describes how to receive automatic picture transmissions (APT) from NOAA weather satellites using Gqrx SDR, record them to a WAV file, and finally decode the images using the free and open source Atpdec decoder. If you follow this guide you can end up with very nice results such as the one shown at the end.

Few weeks ago, or maybe a month or two – I don’t remember, I spent an afternoon trying to build gnuradio-core and gr-audio on Mac OS X without using any macports. It was a casual an undocumented attempt that resulted in a compilation failure. I wasn’t surprised because I made several mistakes along the way, so I just left it an moved on.
