Want free, in depth training on GNU Radio from an authoritative source? Then you’ll want to spend four hours viewing this series of videos by Tom Rondeau, KB3UKZ, the GNU Radio project manager since 2009. Tom provides a detailed, in-depth study of this Software Defined Radio experimental and development system. These videos are taken from the 2012 ARRL/TAPR Digital Communication Conference, held in Atlanta, GA.
NOTE: Per the conference organizers, the Linux/GNU Radio live DVD mentioned in these videos is NOT available for purchase or download due to licensing issues. (This is understandable, but on an editorial note it’s regrettable that the open source movement in general, and SDR related projects in particular, seem to be increasingly mired in licensing controversies.)
