A. Overview
HAMFTZ is a powerful DOS program that can help the radio operator to make
some propagation predictions to any location on the earth. It is based on
the original program MINIFTZ v4.3 and will calculate the MUF, FOT, LUF and
signal strength between two points.
I have translated the BASIC sources (MINIFTZ4.BAS) in C and made a lot of
modifications. HAMFTZ is in a beta phase and has no interface for the input and
output. You'll need an editor to enter the datas needed by the program. The
output will be written in an ASCII file that you can later print.
HAMFTZ is compiled with Turbo C++ v3.0 and will use an arithmetic coprocessor
if present.
B. Copyright
I release this program as Freeware. That means you can (must) copy and distribute
it for free as long as you give all the files that belong to this package.
A commercial use of this program is not allowed. Ask the author for a commercial
use of HAMFTZ. The sources are not free but I think to release them when
the program become more 'usable'.
C. Installation
To install the program, copy the file HAMFTZ.ZIP into any directory
(e.g C:\HAMFTZ) and decompress it with PKUNZIP or UNZIP. It will create
some files and the executable HAMFTZ.EXE. You must always start the program
in this directory.
D. Running the program
To run the program go into the directory where you installed HAMFTZ and
edit the file HAMFTZ.IN (it contains all datas needed for a calculation).
This file is self explainary (I hope so!) and must be in the same directory
as HAMFTZ.EXE .You can then modify it as needed. After you finished to edit
it you can run HAMFTZ. The syntax is
HAMFTZ <inputfile> <outputfile>
E.g. type "HAMFTZ HAMFTZ.IN HAMFTZ.OUT" and after the calculation edit or print
the file HAMFTZ.OUT .This file is also well documented so I don't want to
explain it here (it's planned for the future)
E. History

F. Miscellaneous
This documentation is far from being complete. It will grow as my free time
permits. If someone find errors in this text feel free to write me a note.
My native langage is not english so I need help to write and improve this
text. I will appreciate any comments that can help me to improve this
program. As I work on HAMFTZ in my free time I can't give any schedule
for bug fixes or program improvements. SORRY!
