HF-AIS... what????

Or rather wat?

"advanced DSP core technology which enables an AIS transceiver to reliably and accurately receive and decode every AIS transmission in real time"

So... AIS is 2x9600 baud channels.  Today that is like crazy slow, so why is special DSP technology needed?  Seriously?  Why?  No really... I am totally not understanding.  These are 25kHz max channels which is nothing in today's computational landscape.  Even if you decided to do beam steering and create multiple synthetic channels, this really isn't much.  Shine Micro has had the RadarPlusSM1680 for > 7 years with 8 receivers.  I think that uses GNU Radio inside.
