[hpsdr] CPU board for HPSDR

[Alan Hochhalter]

It's very difficult (impossible right now?) to put together a group of 
separate components in a package as small as a netbook or laptop.  I 
have a system in my car and the 10-inch (~25cm) diagonal LCD by itself 
is thicker than the HP netbook I have.  On the other hand, the netbook 
screen is small, and I think I will want a large screen when full 
capability of having multiple Mercury boards and receivers is there.  
Note that I haven't tried to use the netbook with my HPSDR setup to see 
how it works.

In response to Aivars, Amazon.com sells the Fit-PC2 so you can order a 
single unit from them.  Another, although not as small, option for a 
processor might be something like the MSI Ultra-Thin PC.  There is a 
short video overview here: http://www.mp3car.com/  I haven't tried to 
compare the specs or prices in detail.
