[hpsdr] PowerSDR v2.2.3.dual_Mercury (K5SO 28SEP2011)

[Joe Martin K5SO]

All,

PowerSDR v2.2.3.dual_Mercury (K5SO 28SEP2011) may be downloaded from

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

This new version includes a major revision of the diversity/steering  
window display and user controls for nulling and steering and  
dramatically simplifies doing any of those functions.  The program has  
user input for the physical separation distance between the dual  
antennas (if operating in spatial diversity) and shows the calculated  
antenna sensitivity pattern and directional characteristics directly  
on the display based upon the antenna separation and frequency.  There  
is a new "null adjust" control that makes nulling much easier than any  
version previously.

There is also included a "cross-fire" option that enables a frequency- 
independent null to be achieved via the usual 180-degree phase shift  
used in cross-fire antenna systems.  With this option you may operate  
as with a cross-fire feed system or as without a cross-fire feed and  
the resultant pattern is displayed for you.

If you found the recent dual Mercury program complex and hard to use  
please take a look at this new GUI, it should be much more intuitive  
and easier to use; at least that was my goal.

While I'm still working on a few of the subtle aspects of the  
directional control system I believe everything works reasonably well  
at this point. There are sufficient offsets and calibration inputs to  
allow calibration for most any arbitrary antenna arrangements,  
including a substantially wider range of gain adjustments to  
compensate for different antenna gains.

This continues to be a work in progress, of course, but the current  
version should be much simpler to use than previous versions and  
should be configurable for a wide range of diversity and beam forming  
uses.

This version incorporates Doug W5WC's recent changes/fixes to his  
PowerSDR v2.2.3 as well.

Have fun!
