[hpsdr] PowerSDR v2.2.3.dual_Mercury (K5SO 26OCT2011)

[Joe Martin K5SO]

PowerSDR v2.2.3.dual_Mercury (K5SO 26OCT2011) is available for  
download from

http://www.k5so.com/Dual-Mercury%20Program.html

This new version is in response to user suggestions/requests to modify  
the phase control units to degrees instead of radians.

The change makes relating the phase shift of the non-reference IQ  
stream to a physical steering angle less confusing for those using the  
program to steer the directional sensitivity of a two antenna array.

Thanks for the feedback Frank and Abhi!
