Just a technical writing tip, when you are using any sort of acronym that's the subject of the piece it's helpful to do something like SDR (Software Defined Radio), then use SDR through the rest of the text. Either that or do the blog-style hyperlink the first acronym to the wikipedia page or give a footnote.

Thanks -- you're right. I've added a link and spelled it out completely in the first sentence now.

I second this! I understood that it would be something like that from the context, but I didn't knew what SDR meant until I read the comment above. Great work!
