PlutoSDR

[Alex Fraser]

It looks like the price for the Pluto + dual radio rig is over $150.  
That is the rig with 4 antenna connections.  The two antenna connection 
board is going for ~$80.  These prices seem doable, but I will wait till 
I have a clear plan to fly it.
I had a bit of a setback with the drone I converted.  One of the motors 
is acting odd.  I will have to open it up and see what is what.
