PRECISION MORSE
The Dantong Morse Tutor sends a continuous stream of
precision Morse Code in random five letter groups. Its
sending is impeccable; it never repeats and it never tires.
You can select letters only, numbers only, or letter and
numbers mixed, at the flick of a switch.
OPTIMUM LEARNING TECHNIQUE
Best of all not only can you vary the basic sending speed
from 6.5 to 37 words per minute, you can also increase
the delay between letters from the "correct" value (3 dot
periods) to a maximum of over 3 seconds.
This delay facility means that right from the start you can
learn each letter and number as it ought to be learnt, that
is with the dots and dashes within a letter fast enough to
form a complete sound pattern, but with a long delay
between each letter. As you improve you simply reduce
the delay between letters.
USES YOUR TIME TO BEST ADVANTAGE
Skill at Morse reception only comes with practice and this
uses up valuable leisure time. With Model D70 you can
make every minute count because you can tailor the level
of difficulty exactly to your own ability.
Moreover you are no longer tied to someone else's
timetable. Morse Tutor is available at any time day or
night so you can snatch a few minutes practice whenever
it suits you. This way your practice sessions can make
use of time which would otherwise be wasted, while
travelling for example.
ALWAYS FRESH
Unlike tapes and records whose sequence becomes
familiar surprisingly quickly, the Morse Tutor never repeats
the same sequence twice. This means you don't have to
ration the supply to avoid wasting it.
LEARN WITH CONFIDENCE
Morse Tutors' calibrated controls mean there will be no
doubt about when you are up to examination speed. With
today's examination fees it pays to pass first time.
AFTER THE MORSE EXAM
After Morse Tutor has helped you to pass the Morse
Exam it will painlessly help you to the still higher speeds
which are needed to get the full enjoyment from real-life
operating. Its wide speed range means that even experts
can use Morse Tutor to keep in trim or as a refresher
course.
HOW TO LEARN MORSE WITH THE DATONG TUTOR
The key to learning Morse is to learn each character as a
complete sound pattern not as a set of individual dots and
dashes. It is important also to be able to receive Morse
reasonably well before you begin to practice sending.
Start with Morse Tutor set to between 8 and 12 words per
minute but with maximum delay between characters. This
way you learn the correct rhythmic sound of each
character in the code list. As you become familiar with the
code, gradually reduce the delay between letters. Ideally
the speed should always be slightly faster than you are
able to read comfortably.
Many short practice sessions are much better than few
long ones. Take advantage of Morse Tutor's portability
and personal earpiece to snatch as many practice
sessions as possible. You can learn Morse with minimum
disruption to your normal activities by using time which
would otherwise be wasted for example while travelling to
and from work.
Once you have learnt the basic code and can recognise
the characters from memory, your main practice should
consist of writing down the output from Morse Tutor. Use
longhand right from the start rather than printing,
otherwise as you progress your ability to copy Morse will
outstrip your speed of writing. It is also beneficial to listen
to Morse Tutor's output even at times when you are
unable to write it down. This helps you to recognise the
"tune" of each character and to split up the continuous
stream into separate characters.
Do not be discouraged if your progress appears to come
to a halt at various stages. This is quite normal and in fact
is normally a prelude to a significant jump in receiving
speed.
When you have reached a speed of about six words per
minute you are ready to begin sending practice. Simply
plug a conventional Morse Key into the *KEY' jack on the
rear panel of Morse Tutor. This disables the automatic
sending circuitry and the unit will produce a tone
whenever the key is pressed /(the key should close a
contact when pressed).
INTERNATIONAL MORSE CODE
Morse code comprises a stream of dots and dashes. If the
duration of a dot represents one time unit, a dash is three
units, the space between dots and dashes within a
character is one unit, the space between letters in a word
is three units, and the space between words is seven
units.
When the 'DELAY' control is set to the 'CALIBRATE'
position (fully clockwise) Morse Tutor produces Morse
with the above timing and in five character groups. As
extra delay is introduced between letters the delay
between words becomes just twice the delay between
letters. Timings within each letter are determined only by
the 'SPEED' control.
The basic Morse characters are given below in the form of
dots and dashes. When saying them either aloud are
mentally use "dit" to represent a dot and "dah" for a dash.
Letter C for example is pronounced dahdidadit. It is
important to learn the code as sounds not as visual
patterns.
