Cyberspectrum

Cyberspectrum SDR Meetup

The Bay Area SDR Meetup will serve as a forum to exchange knowledge and ideas related to Software Defined Radio (the software and hardware), and generally aim to get people excited about all the applications that can be realised with the technology. At each meetup, attendees will have the opportunity to present their work/ideas to the group.

Engineers, enthusiasts, hobbyists and people of all experience levels are welcome, no matter what your software/hardware background. Everyone is welcome to submit their ideas/presentations to the pool. For each meetup, a fixed number will be chosen to fit the format. Currently there will be a short show-and-tell section, followed by two 20 minute presentations (e.g. an introduction to an SDR topic and analysis of a mystery signal), and then to conclude a 40 minute in-depth presentation on an application. Suggestions/alterations to this format are welcome of course!

Meetup locations will alternate between the South Bay and San Francisco. Meetup presentations will be recorded and posted online (although you can opt out if you wish).

Bay Area Software Defined Radio #1

Live Stream: https://www.youtube.com/watch?v=DUGr_Z04SKs

Kevin Reid (@switchborg): "A Visual Introduction to DSP for SDR"

A tour of DSP topics relevant to implementation of simple software-defined radios. Focuses on visual explanations of fundamental manipulations of digital signals, including analytic signals, frequency shifting, sampling rates, filtering, and the discrete Fourier transform. http://switchb.org/kpreid/

@SigBlips: the 'baudline' signal analyser, and some interesting signals

Bay Area Software Defined Radio #2

Nick Foster @bistromath

Satellite communications with GNU Radio, SDR hardware, homebrew antennas and satellite tracking.

Josh Myer @xek

A couple months back, some friends and I captured a bunch of RF telemetry from a rocket launch down at Vandenburg AFB, down by LA. I'll talk about how we decided what to capture, what we captured, and how we analyzed the many, many gigabytes of RF that wound up on a hard disk that morning.

Jonathon Pendlum @SDRJon

RFNoC (RF Network on Chip), a new framework for Ettus third generation devices (X300 & E300) that aims to make FPGA acceleration in SDRs more easily accessible. I will cover some background on FPGAs and their use in SDR, the motivation and design of RFNoC, and conclude with a few live demos.
