The following HF propagation models for Windows PCs are available from NTIA/ITS:

Windows-95/98/ME/NT/2000/XP 32-bit HF Propagation Models from NTIA/ITS

  • Version 05.0119W (21 February 2008) - A .zip file that contains ICEPAC, VOACAP, and REC533.
  • Since February 2004, installation is done with Tarma Installer©.
  • WARNING: Do NOT install the software on a Compressed NTFS file system. There are reports that some of it does not work. This is only possible on Windows-NT/2000/XP systems. Do a right mouse click on the drive and show the Properties to verify the file system.
  • As of 23 Feb 99, a new version of Salford's compiler is being used. It is significantly  faster (almost 3 times faster) than previous versions.
  • This has been compiled with Salford's FTN77 compiler for WIN32.
  • It will NOT work on Windows 3.x systems.

Note for Windows-NT/2000/XP installation:
The icons to execute the software may not install properly on Windows-NT/2000/XP systems. Here is a solution:

  • This problem should be solved with version 04.0202 using the Tarma Installer©.
  • Execute the software from Start/Programs/ITS HF Propagation/....
  • You can also now execute any of the ..\bin_win\*.exe files directly

If you can do the above, you can create an icon on the desktop by:

  • Start/Programs/ITS HF Propagation
  • Right mouse click while the mouse is over ITS HF Propagation and pick Explore
  • Then do a right mouse click on ITS HF Propagation and pick Send to > Desktop
  • You can then change the desktop icon to c:\itshfbc\icons\itshf.ico

The above is true only if you use the default installation.


The readme.txt file describes installation and registration procedures (all software is now free).
