enter current SSN/K etc and get a 160 plot?

         You can generally use an 80m plot and subtract ~3 S-units 
(20 dB).  Over the years I've found 80m conditions to be a reasonable 
(but not perfect) predictor of 160m openings, including long 
path.  The very best tool for 160m is a good greyline map (e.g. DX 
Atlas) with accurate sunrise/sunset times.
