This is a build I did on a Raspberry Pi to receive NOAA weather satellite signals and process them into images on a Raspberry Pi 3 Model B. The satellite reception is done with a NooElec SDR dongle and a QFH antenna. You can see my build of the QFH atenna in the video linked below.
All of the SDR reception and image processing is done on the Raspberry Pi, and it is completely automated. Once it is set up, you don't need to touch it (other than to download your images).
