You're welcome, Herb, and thanks for the kind words.  To complement the 
signal propagation prediction, I've gotten semi-absorbed in papers on 
noise power modeling.  You need the 'N' for S/N ratios. :-)  A lot of 
Fortran there, as well, but much more recent (f90) so doesn't have the 
same retro feel as the original Longley-Rice code. I'll share if it 
leads to anything of interest to our group here.
