CW.DOC
I. Background
A. Version
This documentation is updated to version 2.14 of the program.
B. Purpose
CW was written to help prospective hams overcome what many perceive
to be the biggest obstacle to obtaining an amateur radio license--learning
the Morse code. There are several programs available in the public domain
which send Morse code via a PC's speaker, but most are very limited and are
written in BASIC, which requires a clumsy interpreter. CW seeks to provide
a comprehensive program which provides several modes of learning the code.
The best features of other programs are included and many new features have
been added to those otherwise available in public domain software.
C. The Author
The author is a registered patent attorney working with Rockwell
International Corporation in Cedar Rapids, IA (the old Collins Radio group).
He can be contacted on Compuserve (ID No.: 71016,1355), or GEnie (Address:
L.MURRAH).
D. The Software
CW is written in Turbo Pascal. The source code is not included in
this package in order to reduce its size and thus the cost of transmitting it
over the telephone lines. If you are interested in the source code, please
call Ham Central RBBS at the number given below.
II. Equipment Configuration
CW can be run on the IBM-PC and compatibles having 192K of memory and
one floppy disk drive. Neither a hard disk or special graphics cards are
required, although you will find that a hard disk will enhance operation of
this and any other program.
Your CONFIG.SYS file should authorize at least 20 files. This can be
done with the following statement;
FILES = 20
III. Your Right to Use CW
A. License
As you may have noticed I have retained the copyright in CW, primarily in
order to control its orderly development. However, I have granted the right
to anyone to use the program for private, non-commercial use without further
permission from me. That is, you can copy it, use it, and share it so long as
you do not charge any money for it.
You may use and change the source code so long as (1) you retain my
name and copyright notices, and (2) you provide me with a copy of any modifi-
cations along with your permission to include them in future versions of CW.
B. Contributions
Several users have asked me whether I require payment of a "shareware"
fee in order to use the program. The answer is "No"; but if you would like
to support CW with a small contribution (say $1-5), we certainly would not
refuse your generosity.
IV. Tips on Learning the Morse Code
1. Learn the characters by sound, not by sight. Each of the characters
has its own characteristic length and rhythm. Do not memorize the characters
using the visual dot and dash symbols. That will slow you down!
2. Set the character speed to 13 words per minute and the send speed
at whatever lower speed you desire. Since your ultimate goal is 13 words
per minute, it is much easier to learn how the characters sound at that
speed even though they are sent at a lower speed. This helps to eliminate
the "hump" that most people experience around 10 words per minute.
3. Study every day, but if you feel you are stuck and not making
progress, take a few days off. It's amazing how this will sometimes clear
your head.
4. Try to copy code in you head as much as possible.
5. Get access to a ham receiver and try to copy off real transmissions
off the air.
6. As soon as possible learn the sounds of whole words.
7. Turn on the CW <G>roups function and let it send in the background
while you are doing something else, such as reading the paper or working on a
construction project. Try to identify characters while doing the other
activity. This will help your brain shift to "automatic" and will help the
code sounds become a natural "part of the wallpaper."
8. Although the code test no longer requires that you demonstrate an
ability to send code, you should get a code practice oscillator and practice
your sending.
9. As soon as you pass the novice test, get a rig on the air and operate
on the novice bands. Nothing will increase your speed and concentration as
well as the pressure of an on-the-air contact. Don't worry about being
perfect--the other guy is probably in the same boat as you.
V. Tips on using CW
A. Setting Up CW
1. The Configuration File
The default values for code speed, oscillator tone, and screen
colors are contained in the CW.CFG file. These may be changed from within
CW using the <P>arameters and <U>tilities commands in the main menu.
2. The Code Speed
The code speed can be set using the <P>arameters command in the
main menu. You can set the speed at which the character is sent separately
from the overall send speed. For example, you can set the send speed at a
slow speed but set the characters to be sent using shorter dits and dahs
equivalent to a much faster send speed.
3. The Oscillator Tone
The oscillator tone can be set to suit your taste by using the
<P>arameters command and the <T>one subcommand when the parameters menu window
appears.
4. Screen Colors
The colors of the screen, the windows, and the highlighting can
be set to suit your taste using the <U>tility command and the <C>olors
subcommand when the utilities menu window appears.
5. Hiding the Text
If you would like to hide the text so that you are not tempted to
peek, use the <U>tility command and the <H>ide subcommand to toggle the text
display on and off. The current status is displayed on the status line.
6. Speed Test
Although it is unlikely that you will need it, you can check the
speed at which CW sends by using the <U>tilities command and the <S>peed Test
subcommand. Simply count the number of time that the word PARIS is sent in
one minute, and that will be the code speed.
B. The CW Status Line
At all times while CW is running, the status line at the bottom of the
screen will display from left to right the mode, the code send speed in words
per minute, the code character speed in words per minute, the oscillator tone
frequency in cycles per second, whether the text is displayed or not, and the
key which must be hit to exit the current operation.
C. Starting Out
1.The <L>earn Function
Use the <L>earn function to learn the basic DIT and DAH sounds and the
characters. The characters are grouped with other characters having similar
sounds to facilitate learning. Simple tests are provided to test your
recogniiton of the DIT and DAH sounds and the characters.
2. The <K>eyboard Send Function
You may wish simply to select enter individual keys to hear how they
sound. This is the purpose of the <K>eyboard send function. At present it is
not possible to type ahead of the CW sender. Therefore you should wait until
a key has been sounded until you enter another key. Otherwise some characters
may be lost.
D. Increasing Your Code Speed
Once you have mastered the character sounds, you can work on increasing
your speed. CW provides several ways to do this:
1. The <G>roups Command
One of the classic ways of practicing code reception is sending
five letter groups of random characters. The <G>roups command does this.
2. The <W>ords Command
If you would rather work with real words, use this command. In
order to promote recognition of whole words, the words are not printed on the
screen until the entire word has been sent in code.
3. The <Q>SO Command
Use this command if you would like to copy a simulated QSO (a
radio contact). A standard pattern is used, but the call signs, names, etc.,
are randomly selected from a list.
4. The <E>nter Command
With this command you can have a friend enter test via the
keyboard, and you can attempt to copy it without looking at the screen.
5. The <D>isk Command
This command sends the contents of a disk text file in Morse code.
You can practice by having someone create a text file of unknown content using
a word processor. Another idea is to exchange disks with a friend who is also
studying the code and carry on a 'disk QSO' between the two of you.
6. The <T>est Command
This command lets you test your approximate receive speed. The
computer will send a character and wait for you to type in the correct key.
When you exit this function using the ESC key, the computer will print out
your the approximate send speed, your approximate receive speed, and your
accuracy rate. This command can also be used to learn to copy code on a
keyboard. Although you will not be tested on a keyboard, it is the fastest
way to copy code and is the methos used by all the military services.
VI. We Need Your Feedback
As I continue to improve CW, it is helpful for me to have you feedback
about what you like about CW, what you don't like about it, any bugs you have
discovered, what you would like to see changed or added, etc. Please take the
time to fill out and mail the form in the file FEEDBACK.FRM to me. It would
be much appreciated.
