[hpsdr] Fwd: Re: kind of Hermes back to open source version

[Scott Cowling]

Hi Arseniy,

You have described almost exactly the 
architecture that we have been discussing for 
what I call Gen2. We will keep the Atlas 
connectors on the new main board to allow use of 
existing boards, but the connections will not be 
"bused", so some performance will be gained even with Mercury and Pennylane.

New boards will use the high-speed connectors and 
performance will be very much improved.
