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

  • Version 05.0119W (21 February 2008) - Contains ICEPAC, VOACAP, and REC533.
  • Installation now (2 Feb 04) is being done with Tarma Installer ©.
    • This should solve the desktop icon creation problems on Windows-NT/2000/XP
  • 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.
  • As of 23Feb99, 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.
  • There are reports that ICEPAC may hang on AMD processors.

If you have problems and want to ask for help, please do the following:
  • Execute the file: C:\itshfbc\bin_win\sysinfo.bat
  • If you did not use the default installation directory, C:\itshfbc will be different.
  • This will create the file: C:\itshfbc\bin_win\sysinfo.txt
  • Please include that file in your Email with a detailed description of your problem.

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.
