[hpsdr] Triple-Mercury program user information document

[Joe Martin K5SO]

All, 

I have prepared a seven page PDF document that may prove helpful to you if you wish to run the triple-Mercury beam steering program PowerSDR v2.2.3.triple_Mercury.  It can be downloaded from 

http://www.k5so.com/PowerSDR_v2.2.3.triple_Mercury_user_information.pdf

The document is not a step-by-step instruction manual for running program.  Rather, the goal of the brief document is to provide insight for the user as to how the steering program operates and, in particular, what the controls in the Steering Control panel do.  It is assumed that the user is familiar with the general operation of PowerSDR.
