At the 31th Annual ARRL and TAPR Digital Communications Conference held last September in Atlanta, GA, FlexRadio VP Stephen Hicks N5AC gives an in depth presentation on SDR and its potential. He outlines his company’s new Flex 6000 series, a Linux based commercial product based on components used in government radios. While this is not an open source project, it’s still an interesting presentation on SDR from the commercial perspective.

The actual talk, after the preface remarks, begins at 3:30 into the above video.
These FlexRadio Boxes are outrageously priced IMHO (only).
