GRCon23 - Receiving Faxes with GNU Radio - by Matthew DeMorat 

I will be presenting a method of receiving the NOAA weather fax system and viewing the transmission in real time using GNU Radio. This presentation will go over the process of creating a simple HF antenna, receiving HF on an RTL-SDR, how to decode APT (Automatic Picture Transmission) signals, and how to view faxes in real time. I will also touch on issues faced while creating this project, a brief history of radio facsimiles, and show some images that were received. As part of this presentation the GNU Radio implementation will be demonstrated.
