i have taken a different track with my software.  i want to know when any given
band will be open to anywhere given the best possible antennas and max power. 
that way when i plan for m/m operations i know how many operators are needed at
any given time to cover all the open bands.  that is also why i call my
predictions 'mof' and 'lof' instead of trying to predict signal strengths or the
'muf'.  for the 'average' station it is probably over optimistic, but for what i
want it does the job.
