[hpsdr] CPU board for HPSDR

[Kevin Wheatley]

This is going to be an interesting thread :)

I've been thinking along the same lines, however it's the system as a  
whole that really need discussing, i.e following the motherboard, what  
about the peripherals?
OK there are many choices to be made and yes you could squeeze all  
this inside a small box, but what about keyboard mouse and display.
I (currently) think the best overall option would be for one of the  
better performing netbooks. This will give you a physically small foot  
print, with the performance to run PowerSDR, however I'm not sure if  
this would meet (the soon) future requirements. For example multiple  
receivers (4 currently planned for Hermes) and the GUI modifications  
to support this.

The GUI development is really going to be interesting, how about a  
spinning cube with each receiver on a different 'face', when you start  
to think about what the GUI will look like in the future, my mind  
'Boggles' :)

Just my 2 cent worth.
