[hpsdr] Potential New openHPSDR Project

[Henry Vredegoor]

Hi Phil/Jani, All,

This project sure would be a nice addition to the HPSDR system!

(This reminds me of the discussions going on during the "Call For 
Comments" for Ozy II....)

I see the Hawkboard has a 10/100 Mbit/s ethernet on-board!
I also noticed that the Hawkboard is $ 95, compared to the BeagleBoard $149

I had a look at the expansion interface of the Hawkboard..
A lot of signals - not sure if these are usable for transferring high 
speed data to/from the adapter board/ATLAS bus.

I would like to offer my help as a project team-member for 
building/testing/reviewing (prototype-) hardware and testing software.

73's,

Henry.
