Today I had the privilege of speaking at the first MISC.conf (http://www.misc.mn), where I discussed Software Defined Radio 101. In this talk, I cover some of the basic hardware and software tools for getting into SDR, focusing on using SDR# in Windows. I've provided some links to helpful resources to get you started. In a later blog post, I'll try to outline some of the content that was discussed that isn't reflected in the slides.
The slides are available here. http://www.slideshare.net/MikeSaunders4/sdr101presentationdistro
