Oh thanks Dave, I just couldn't imagine what kind of calculator 
it might be.  I was thinking it was a hardware box like a 
Calculator you do math with.  73, Jim

Jim,

This calculator will plot the line-of-sight signal distance 
between two
stations on VHF or UHF.  In other words the typical non-enhanced
communications path over which the two stations can have good 
reliable
communication.
