[hpsdr] How to use the phasing slider control, PowerSDR v1.19.3.1.diversityX

[Joe Martin K5SO]

Duh!  Sorry for the mis-step in the explanation, of course the peak  
setting is 180 degrees out of phase with the null (not 90 degrees)!   
The procedure using "null" should be to move the slider to a new  
position that is 180 degrees from the null.  I've made the correct  
notation in the Wiki.
