• “L-Band WX Satellites” (Joe Steinmetz @usa_satcom (

This presentation will cover most aspects of receiving, demodulating and decoding current L-Band Weather Satellite signals (NOAA, MetOp, Meteor, FengYun, GOES). Topics will include hardware, software, de-modulation/decoding techniques, challenges, flows as well as cool sample images and data.

• "Disposable, Stealthy, Cheap SIGINT" (Chris Kuethe (, @kj6gve)

This presentation covers some observations and considerations for using inexpensive and compact ARM boards for signals analysis.
Topics may include: power budget, air interface, attributability, performance tuning, lolcats and doges.


Joe is a computer engineer with a long history of high performance silicon development in the storage networking space. As a hobby (that is way out of control) Joe has been developing various software decoders for the last 10 years. Most of these decoders have been focused on various data/voice services from such L-Band satellites as Inmarsat and other un-named commercial Ku birds.
