09 Jul 2012 News for NTIA/ITS HF Propagation Models (WINDOWS version) 09 Jul 2012 1. I forgot about the version triggering the original IONCAP absorption model. Thus: Version 12.0709W = normal code Version 12.0709I = use old IONCAP absorption model Version 12.0709A = use Alex's changes with normal absorption Version 12.0709a = use Alex's changes with IONCAP absorption Remember, you need to change the data file: ..\database\version.w32
