The 20th Cyberspectrum Software Defined Radio Meetup

Every month SDR evangelist Balint Seeber hosts the Cyberspectrum Meetup in San Francisco, where many SDR fans come together to listen to various presentations. The 20th Cyberspectrum SDR meetup has now concluded, and the recorded video is available on YouTube.

The talks this time include a very interesting talk by Joe Steinmetz (@usa_satcom) about decoding L-Band weather satellites such as NASA GOES. Previously we made a post regarding GOES where Reddit user devnulling showed his GOES reception setup. To save time, on the video Joe’s talk starts at 00:10:45.

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.


 The second talk is titled “Disposable, Stealthy, Cheap SIGINT” is by Chris Kuethe, @kj6gve and delves into topics relating to low cost signal analysis. Chris’ talk starts at 1:45:00. The blurb reads:

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.

Thanks, L-band weather satellite reception is on my “to do” list! I have been experimenting in-doors with WiFi cantennas feeding a 76cm dish into a TP-Link dongle; I was then going to try to receive some Ku-band FTA signals using a universal LNB and either RTL-SDR or a cheap DVB-S2 decoder I bought on eBay. Then once I know what I am doing with dishes, onward and upward we GOES! (sorry pun)
