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. Thanks, Mike Markowski, ab3ap
