******************************************************************
As of 2 Feb 2004, installation is being done with the Tarma Installer.
This should solve problems with creating the desktop icons on
Windows-NT/2000/XP systems.
Installion on diskettes is no longer available.
******************************************************************

This is the current release of the Windows version of the
ITS HF propagation prediction software. The first OFFICIAL release
of the Windows version was 15 May 96. All previous versions were
Beta test versions. ICEPAC, VOACAP, & REC533 are all obtainable
from the Internet site listed below. All are available without charge.
******************************************************************
******************************************************************
* Note: 1) The Windows version is complete. *
* 2) HELP files are done. Additions will always be added. *
* 3) ICEPAC, VOACAP, and REC533 are available. *
* 5) itshfbc.exe (32-bit) for Windows 95/98/NT/2000/XP. *
******************************************************************
* Note: 1) DO NOT install the software in a directory that does *
* not conform to DOS file names. For example, DO NOT *
* install the software in the Program Files directory. *
* The blank in the directory name will cause problems. *
******************************************************************
See the NEWS files for recent software changes.

The software is available FREE via the internet at:
www.greg-hand.com/hf.html

Look for HFWIN32 and Versions and you will see files such as:
itshfbc_051218.exe
That identifies the year, month, day created.

Place this file in a temporary directory and install it by
executing it.

Installation from 1.4 MByte diskettes is no longer supported.

******************************************************************
Suggested system configuration:
The software was developed on:
Pentium 4 - 2.80 GHz
MS-Windows-2000 - Service Pack 4
1 GBytes ram
20 inch display using 1280x1024 raster points/256 colors.

Minimum system requirements (for 32-bit version):

System running Windows-95/98/NT/2000/XP
4 MBytes ram - 16 MBytes recommended
depending on how many applications you have open, you may
obtain the message "Insufficient Memory for Application".
Closing unnecessary applications or increasing the virtual
memory under Control Panel - 386 Enhanced can remove this
problem.
Hard Disk - 20 Mbytes + lots of extra depending on use
VGA graphics card
The software will work on a 640x480 display, but if
possible, configure your display to use more.
A 14 inch display works well with 800x600. If your display
uses only 16 colors, the graphics plots will suffer.
At least a 486x33MHz processor with math co-processor
(a 386 will work but is too slow for any substantial work)
Black & White graphic output can be made to any Windows printer.
A laser printer with minimum memory (512k bytes) will work
but you may need to remove the border from the plot.
Color graphic hard copies - works to some devices, but some drivers
do not seem to work well. HP PaintJet has problems, but it
appears to be the driver fault. Other color printers do work.
