Why, only the most coolest, yet
challenging mode of communication on the international air waves!
We'll assume that you're already
familiar with the
concept of Morse code, but if you need to brush up on it click [here].
Radiotelegraphy, now simply referred to as "CW," had it's
in the railroad telegraph days of the 1800s using a system of
electrical code pulses co-developed by Samuel F.B. Morse. The
first decade of radio communications would see the exclusive use of
Morse code by use of spark-gap transmitters. The signals
by these transmitters were not only inefficient but extremely messy as
their noisy "damped waves" would fill the radio spectrum.
In time, Amateur Radio operators (hams)
vacuum tube oscillators, producing very pure notes as a
"Continuous Wave" (CW) would be transmitted on an exact frequency,
which was not only more efficient, but able to be sent vast
distances, if not around the globe. Today, the
progeny of CW
technology, in the numerous variations of robust and fast digital
communication modes, make up the backbone of smartphone and
functionality and is something we all take for granted.
Morse code telegraphy is certainly not
dead in the
present day for sure. Though, no longer required by any
agencies, a sizable demographic of the ham radio hobby still enjoy
operating in CW mode. The skill and practice required to

proud of their keys which are often expensive and often handcrafted

sense of nostalgia but is just as useful and relevant today. The CW
signal is able to pierce the worst atmospheric conditions and poorest
propagation and there are many radio designs for this mode that most
hams can build themselves, even in kit form with just a basic
understanding of electronics.

The Morse code is more about
and all about timing.
Many new to Morse code struggle memorizing and learning to
at speeds higher than 5 words per minute. Their failure is
not because they lack the talent or intelligence to do so but simply
because the method they used to learn was inherently flawed.
listening to outdated audio lessons [tapes] and muddle their brains
with mnemonics, flash cards, visual "follow-alongs" and even lookup
tree charts which can only serve to add extra unnecessary steps in the
mental process, at the least, ruining a fresh learner's
and at the worst, permanently impeding the learner's ability to
increase copying speed proficiency.
There's a beauty and symmetry to the
sound. The dash, or "dah" elements are [supposed] to be three
times that of a dot, or "dit" with a dot being defined as 1
The intra-element spacing is also to be 1 unit in
The inter-character space is 3 units and the space between
is to be 7. This
is only a suggested guideline
and in reality, spacing ends up being left to the discretion of the
sender - some having light "weighting," or the proportion in
duration of the elements, some heavy and others may have a particular
style, like the "Banana Boat Swing" or "Lake Erie Swing."
Good code is only defined by how 'legible' it is to copy and
essentially the 'voice' of the sender, but through their 'fists'.
It's all in the sound...
The proper and best way to learn Morse code is
Sound is obviously the core component to [audible] Morse
Do you (the new learner) believe that learning the distinct
of at least 40 letters, numbers and punctuations will be a daunting
task? Let me then ask you: When you go outside on a
day, stand still and close your eyes, what do you hear? Do
hear a bird? What kind of birds? Blue jays?
Maybe the hooting of an owl? Did you hear a nearby
passing? Are the tree tops filled with the buzzing of
How did you figure out what was what? There are
sounds in any particular daily experience, yet the human brain can
easily and instantly classify, discriminate and identify about each
one. Surely you can do the same with a simple code!
You only listen to the sound of
character, and then
write the character down or mentally picture it. Thats it!
Despite the numerous learning methods and money-making
that have done more harm than good to new hams over the years, there
are a couple that have proved successful to millions. The
proficiency is slow, tedious and repetitive, as they should be
like learning any language, but you too will find yourself knowing the
code. The Koch and Farnsworth methods are the two
best implementations for learning.
These methods are really just two sides
of the same
coin and each modern leaning platform uses some variation of them,
whereas you start off with one particular character, with the practice
code being sent at a [higher] speed such as 20 wpm, but the space
between each character sent is spread out to whatever the learner is
comfortable with, like 5 wpm. Like I described above, the
is the easy part. Faster-sent code has more a sound to it

table, which are bad habits you should avoid at all cost.

accuracy will a new character be added to the practice list.

Morse Machine for Ham Radio
by Andrea Salvatore, IU4APC, can be downloaded from the Google Play Store or from Amazon
for only $1. A Morse machine is a method by which a list of
characters are displayed with some kind of stats or bar graph, whereas
when the code is played you are timed on how fast you're able to press
the keyboard key for that character.
As per the
method, only one character at a time is added until you master it.
Getting the wrong character will set back your score for that character
so the app will try to work with you to master it. A Morse
will train you to better connect the sound to the character in your
mind as quickly as possible.

A classroom setting
alongside other hams new to CW may be the most effective
learning tool for you. Many local radio clubs offer such
classes, either in person, over a Zoom conference setting or on the
air. You'll also find many YouTube Morse code training
sessions which will definitely be worth the investment of time.
Keys - So many to choose from!
Once you've learned the code you'll
wish to send
it, and maybe even try your hand at practicing with others [who are
often very willing] on the air, it will be time to choose the right
key. A key, for those who are really new, is basically am
electrical switch, even hearkening back to rudimentary 'Steampunk'
aesthetic of the 1800's golden age of railroading. There's no
need these days to use a CW key as you can send with your computer of
course, but just as with an automobile, motorcycle, firearm, knife or
watch, a fine example of a key will practically 'sing' in your hand and
you'll connect with the code as with any precision instrument.
The better the key, the better the feel and even the timing.
Many keys, especially limited edition
models, just like the other items mentioned above, can come with hefty
price tags to go with the heft of their weighted bases. You
get what you pay for BUT you certainly don't need an expensive key to
enjoy the CW bands! Using my tutorial, you can build a
key for around $10, although there are many quality keys for purchase
online which are in the $80 - $150 range.
When choosing a key to purchase, you should take the time to
"test drive," not only different types of keys, but different models
from many different manufacturers. An easy way to do this is
visiting a regional Ham Fest. What? You've never
Ham Fest... man, is that going to blow your mind when you do!
local events are the Huntsville, AL fest and the Orlando, FL HamCation.
There are often many vendor booths with their wares sitting
on display tables, each connected to code practice oscillators.
They encourage your to try them out because, maybe you'll
love with one.
When a key comes to
mind, many will first think of the old single arm straight key like the
old brass ones found at railroad telegraph stations of the Old West
days. Well there are [at the least] four other kinds! You
basically have two categories of key types including both Hand-Sent and Electronic.
The hand-sent varieties include the Straight Key, the Side-Swiper and
The electronic keys include the Dual-Lever Paddle
and the Single-Lever
There are also other variations including finger tap keys (in
dual and single) and even capacitive touch-sensitive which consists of
just two contact studs built into your radio for instance.
you can see some of my key anatomy breakdowns. Model
materials and actuation methods are as individual as the designer,
machinist or homebrewer who thought them up.
The Straight Key is the simplest and most iconic.
range of speed generally goes only into the low 20 wpm's, but more if
you're fast. There's just a lever, a knob, some springs and
contacts. The sending method requires more arm than wrist
and may be quite fatiguing, but the sound produced by this key can be
the most personal.
otherwise called a "Sidewinder," "Cootie" or "Double-Speed" key was the
next obvious evolution and employs a piece of spring steel mounted
sideways with redundant contacts facing each side. When the
handle is gripped and moves the arm left or right a contact will be
made. There is a special method of sending whereas you always
start each character's first element off with a movement to the left,
alternating direction on each element. You can easily reach
speeds up to the 30 wpm's and is much, much less fatiguing to use than
a straight key as the arm can rest on the table. They are
to build at home, requiring an old hacksaw blade and a few pieces of
hardware. The sound of a side-swiper comes across with a
The "Bug," otherwise
known as a Semi-Automatic key is still a very popular option, going
back to the early 1900's and can still be purchased new today from
companies like Vibroplex with very little variation from early models.
It's generally the most mechanically complex of most keys
side-actuated swing arm held in place by spring returns.
the arm to the left causes a contact to be made which is exactly the
same as a straight key, but turned to the side. Dashes are
with that actuation and can be used to send code as a straight key if
desired. Moving the arm in the rightward direction causes a
weighted pendulum, comprising the back portion of the swing arm, to
vibrate or oscillate against a spring-loaded contact point, which
produced "automatically" repeating dots. Moving the pendulum
weight or changing it will likewise change the oscillation speed of the
dots. Sending speeds, by default, sit in the 30 wpm's and
hams can send into the 50's! However, many hams enjoy slower
beginner speeds by adding weight. The sound of this key comes
across as having a potentially "light" weight with tell-tail dashes of
seemingly longer duration.
Dual-Lever Paddle, otherwise called a "Squeeze Key" or "Iambic" paddle
and came about around WWII with the advent of more advanced electronic
keying circuits. Each paddle needs only move a very minimal
distance [even the thickness of a piece of paper] to make contact and
for this reason is the least fatiguing and most comfortable to use.
Sending speeds can also be at blinding rates, even into the
but because the two contacts actuate electronic timing, new senders
especially like paddles as they can send perfect 'PARIS' code as slow
as they wish! Pressing the Left paddle with the thumb
actuates automatic dots and pressing the Right paddle with the index
finger will actuate the dashes. "Squeezing" and holding them
down at the same time actuates an "iambic" action whereas each elements
will alternate, generally with the first element, either dot or dash
happening first depending on which key was held first. Iambic
keying is not hard to master and I go in depth on the subject in my Minty Keyer post.
The Single-Lever Paddle is implemented
same setup as the dual-lever paddle, with each opposing press of the
paddle swing arm actuating their associated contact. The only
difference is that there is not squeeze keying so iambic-like timing is
up to the keyer circuit. Many prefer this variation as it is
forgiving and less error prone to send over that of the dual-paddle and
for that reason some of the high-speed code sending champions of the
world use this key to send code at "plaid and ludicrous" speeds into
the 100's of wpm's! The sender can also wire each of the two
contacts together and use as a variation on of the side-swiper.
Keys can come in any size and material,
nice table-top works of art, to micro-mini "trail-friendly" ones that
can strap to your leg. There has even been a more recent
3-D printed models and alternative sending implementations
including capacitive touch-sensitive, laser path blocking and finger
movement machine-learning image classification. Really, the
is down to the CW operator's imagination and wallet, and are even great
to collect and curate.
If your pockets aren't deep enough to
spring for a
decent key, as some of them can be really expensive, then consider
making your own. See below for instructions on making your
Side-Swiper "Cootie" key. Before you do, check out one I made
just a few minutes out of a bunch of junk parts! [CLICK HERE]

I spent a few years learning
the code using online tools and software, but it wasn't until one of my
dearest of friends, now a "Silent Key," invited me to joint the local
practice net with him that I saw an increase in my proficiency.
We would then spend an hour, and sometimes two each Wednesday
night doing "GUD CODE BAD," and I soon found myself having rag-chews on
the HF CW ham bands.

Sets to Sideband A
Guide to Building an Amateur Radio Station By
Frank W. Harris, K0IYE [2019
- Revision 15]
K0IYE, challenges YOU to be "The Complete Ham!"
This awe inspiring 748 page book chronicles his experiences as a radio
homebrewer through the last two decades and does well to educate the
reader, not only on the fundamentals of electronics but time-tested
techniques for experimentation. He takes the reader step by step
through his progression of building a ham station FROM SCRATCH, sharing
an intimate journey, of not only his building successes but of the
lessons learned from his technical setbacks, detailing for you, the
reader, each circuit; their construction and fundamentals of
operation. Frank’s book has become an “icon within the ‘QRP’
community”, a bible
of sorts to the art and practice of homebrewing.
First written in 2002, Frank has donated his book to the free enjoyment
and use of the Amateur Radio community! Many sites carry
of his publication, mostly in a per-chapter format and after [at least
two] decades of exploration he is now up to the 15th revision. The book
starts off from the beginning of ham radio with a history lesson on
discoveries wrought by our technical forefathers, then it builds from
there and topics covered include everything under the ‘ham radio’ sun
from; the fundamentals of electronics, basics of homebrewing, how to
set up an electronics workshop, as well as detailed breakdowns of
nearly every step of a radio’s operation. Follow Frank from CW to AM,
through SSB to FM and more as he works with every type of component
from vintage tubes to modern micro-controllers. Did I mention that the
book is a free download?
His building philosophy is simple: to really appreciate the intimate
understanding of a homebrewed radio’s operation, it should not only be
constructed from the most basic parts such as transistors and other
discrete components, but its circuits should be sound in design and
when built, should reflect good ‘Amateur Practice’; such as using
simple and modular construction, and going out of your way to comply
with FCC emission standards. At one point, to test his ham radio
fortitude, he literally hewns galena ore from a rock to fabricate a
‘crystal’ receiver! Frank coins the term “The Complete Ham” which
describes an Amateur operator whom sets out to not only be a
well-rounded operator but strives to understand how his equipment
works, as well as being better able to repair and enhance his or her
