VOACAP is considered by many to be the defacto standard HF propagation prediction tool.  Although originally developed on UN*X, the official release of VOACAP is now maintained on Windows (using the Salford Fortran compiler). This project represents an effort to compile VOACAP using the GCC GFortran compiler and create a set of OSS support utilities.
