INTRODUCTION
CWT 11.3 is a FREEWARE program. That is, you may copy, distri-
bute and use it without any restrictions but these:
1. You are not allowed to charge any amount of money for it.
2. All copied files must be handled over in their original form
and content.
3. You are not allowed to use CWT 11.3 in a business, commercial,
government, or institutional environment except for evaluation
purposes.
All texts and graphics of CWT 11.3 are carried out in German,
support for English or other languages has not been provided.
Nevertheless you will find the program comparatively easy to
handle even though you may not speak any German at all. And
CWT 11.3 offers some special functions not commonly found in
comparable freeware or shareware programs. Thus it still may
serve you well to some extend.
The following gives you a brief overview of all files included
in the original distribution file. Those absolutely mandatory
for running the program are marked by the letter '*'.

WHAT CWT 11.3 HAS TO OFFER
CWT 11.3 is a morse code trainer for radio amateurs providing the
following futures:
- a clearly structured, neither cluttered nor primitive graphic
user interface closely kept to SAA standards which makes the
program pleasant and easy to use
- a code generator capable of sending random groups of equal or
different length, common (German) words, abbreviations for CW
work, amateur text (automatically generated) and external text
files
- an integrated editor for creating the latter mentioned text
files
- a decoder which reads code characters from an externally con-
nected morse keyer and converts them into readable text (morse
keyer connected to the parallel port)
- a »bar writer« which reads code characters from an externally
connected morse keyer and converts them into graphic bars
- a possibility of saving all important configuration parameters
for later use
- support of SOUNDBLASTER compatible cards including several sound
effects like QRM, QRN, QSB and QSD
EQUIPMENT AND SYSTEM REQUIREMENTS
- an IBM compatible PC equipped with a 286 series processor or
higher
- 450 kB free memory
- approximately 950 kB free disc
- a VGA video adapter
- a parallel port for connecting a morse keyer
- optionally a sound card (SOUNDBLASTER compatible)
- MS-DOS, PC-DOS oder DR-DOS (version 3.0 or higher)
HOW TO INSTALL CWT 11.3
First copy all files into a common directory of your choice. If
you do not take further measurements you MUST then start the pro-
gram from within this directory. Otherwise CWT 11.3 will not be able
to find its files. Alternatively (and certainly more comfortable)
you may include the following instructions in your AUTOEXEC.BAT:
┌───────────────────────────┐
│ SET CWT=[[drive:]\path] │
│ │
│ PATH [[drive:]\path] │
└───────────────────────────┘
Assuming you have copied the files into a directory called »CWT«
on drive »C:«. In this case you must include:
┌──────────────────┐
│ SET CWT=C:\CWT │
│ │
│ PATH C:\CWT │
└──────────────────┘
If a »PATH« instruction already exists in your AUTOEXEC.BAT and
assuming the complete instruction to read like this:
┌─────────────────────────────┐
│ PATH C:\MYTEXT;C:\MYTOOLS │
└─────────────────────────────┘
Then the new instruction should read as follows:
┌────────────────────────────────────────┐
│ PATH C:\CWT;C:\MYTEXT;C:\C:\MYTOOLS │
└────────────────────────────────────────┘
Next reset your computer once. After this has been done you may
start CWT 11.3 from within any directory whatsoever by just typing
[CWT] at the DOS command line and pressing <RETURN>.
As CWT 11.3 uses one of the system timers which function is al-
tered by software you should not try to run the program under
WINDOWS. But instead you may try run CWT 11.3 from an OS-2 com-
patibility box. The author has not been able to carry out a suf-
ficient series of tests because no OS-2 is installed on his com-
puter, but several users have frequently reported that it works.
Just be aware of the fact please that some functions of CWT 11.3
are a bit critical regarding time consumption. For this reason
you should avoid multitasking operation while running CWT 11.3
unless your computer is sufficiently fast.
USING A SOUND CARD
SOUNDBLASTER compatible sound cards are supported. The default
setting forces CWT 11.3 into using the PC speaker as sound out-
put device. Thus you first must alter the setting if you have
a sound card installed and want to use it. This can easily be
mananged from within the program. Simply open the pull-down me-
nu named »Einstellen« by pressing <Alt>-<E>. Then move the cur-
sor to the row called »Blaster« and press <RETURN>. Please note
that CWT 11.3 automatically checks for a SOUNDBLASTER compatible
card. If none is detected the »Blaster« row in the above men-
tioned pull-down menu remains locked. Therefore make sure that
your sound card is set up properly for SOUNDBLASTER compatibi-
lity before starting the program. In case of troubles consult
the manufacturer's manual.
HOW TO CONNECT A MORSE KEYER
For this purpose your computer must be equipped with a paral-
lel port. For connecting a keyer get a suitable 25-pole plug
and carry out the following job:
The morse keyer must be connected to the parallel port by means
of a one-pole SHIELDED cable. Solder the cable's inner conductor
to PIN 10 and the shielding braid directly onto the plug's metal
flange. Both serve as the keyer's lead lines. The following dia-
gram illustrates the correct connections seen from the plug's
back.

In case your computer provides more than one parallel port you
should choose LPT 1 for connecting the keyer, because by default
CWT 11.3 assumes the keyer to be connected right there. But if
desired you may select another port from the menu »Einstellen«.
Please note that there must be NO voltage on the keyer's lead
line. Therefore only mechanical hand keyers or elbugs with in-
built, separating relays at their output ports should be used.
Otherwise some sort of protective hardware interface would be-
come unavoidable to prevent the port from suffering severe da-
mage.
SOME BASIC HINTS
Whenever you start running the program, the generator's window
will first appear on the screen. In order to start the character
generation simply press <Space> (called »Leertaste« in German).
All important parameters for keying, group generation, character
set and sound can, of course, be altered. This can either be done
by opening the above mentioned pull-down menu »Einstellen« or by
just pressing the following function keys:
┌────────────────────────────────────────┐
│ <F5> set keying parameters │
│ │
│ <F6> set group generation parameters │
│ │
│ <F7> alter character set │
│ │
│ <F8> set sound parameters │
└────────────────────────────────────────┘
The <F4> function key is provided for toggling between genera-
tor and decoder. The bar writer (called »Morseschreiber« in Ger-
man) can be activated by pressing <F10>. All those other func-
tions which have not been mentioned here can be figured out
easily while running the program.
Of course I am aware that this text is by far too scarcely kept
to be called a documentation at all. The same by the way is true
for the German text version simply due to the fact, that all op-
erating instructions can be obtained from an extensive online
help system. You may probably not be able to benefit at all from
the latter but please consider, that CWT 11.3 in its present ap-
pearance has chiefly been developed to serve the needs of German
radio amateurs only. And after all, writing any reasonable manual
or online help in English would certainly be far beyond my capabi-
lities.
