This is the D-STAR Forum from the 2016 Dayton Hamvention, and a pretty long coda at the end from Gary.
There are some slides, but I think this is a fairly good radio show, especially since it's pretty long.
Scotty Cowling WA2DFI from HPSDR and TAPR; Jared Boone AF7SO from ShareBrained Technology and Great Scott Gadgets (HackRF); and Steve Hicks N5AC from FlexRadio Systems team up to make this engaging presentation from their points on the SDR 'spectrum.' As you'll hear, the room was SRO (crowded and hot).
I'll point out one thing that was missing: the other guys. Our team acknowledges that SDR is the future, but they didn't make any specific references to some of the newer players who are stepping in. ICOM is the first of the "Big Three," then Elad from Italy and Expert Electronics from Russia were all showing full-featured, stand-alone direct-conversion SDR transceivers. Elecraft was there, of course, with a new portable. They've been SDR for years, but not direct conversion. Anything cooking there? And there are several smaller entries in receivers and specialized equipment.
This is maybe a C+ for audio. Maybe a B-. Lots of slides, of course (especially Jared), but I think you'll get the point just listening.
