Learn CW (Morse Code) as a language

by Duane Ausherman in 1988


This was first written, in 1988, when one had to learn something to get a ham license.

Over the years I have heard people discussing how difficult it is to learn the code. I will never forget the difficulty I had in learning the code, but I finally did and now I love it. I began thinking about my learning process in an effort to try to understand this problem. Remembering the false starts and blind alleys I followed, brings back the frustration that many voice today. The old excuses of laziness, lack of motivation, "I just can't hear those dits", apply as much as ever, but doesn't explain most of the problems. So why is it so difficult? Here are my conclusions. CW is a language, just like English or Spanish. We receive (hear) it the same way as other languages, but we transmit (speak) it by a different method. If any doubt exists about CW being a language, check with Webster. Think about sign language. It is received with the eyes and sent with the hands. Nobody argues that signing isn't a language. Fluent means the ability to speak effortlessly in a smooth and rapid manner. Let's review how languages are learned.

The first thing that a child utters is usually "ma ma" or "da da," because it is something that is very important to the child. This first word is spoken at about the normal rate of fluency. Then words are added and always at the rate of fluency. As the child's experiences expand, the vocabulary follows. Historically we have learned that code is some kind of converted English. We start with the full vocabulary, and all efforts are put into increasing the speed. This is about as backwards as possible. Imagine learning Spanish by somehow getting the full vocabulary and speaking the words slowly, then a bit faster and then faster yet. The words would sound completely different at each speed and must be learned all over again. Actually CW is an international language and little of it can be taken literally in English. Maybe we can learn something by talking to those "high speed" CW operators (one capable of at least 30 to 40 wpm and understanding by hearing, with no pencil). The question is "At what speed did you feel that you were fluent with CW?" The answers came in around 30-35 WPM. These operators were eventually able to add another 5 to 25 wpm to their speed. Some of their comments were quite revealing. "I hear words and phrases, not letters." "When the speed drops down to about 18 WPM I must grab a pencil, as I forget what has been sent." "I only use a pencil for notes, just as I do with voice." Fast CW is just fluency in Morse code.

You might ask "Why learn 35 wpm when I only need 20 wpm for the fastest test?" That is a good question and the answer is easy. The Extra requirement of 20 wpm is so slow and under the rate of fluency that it is actually hard to copy. It's natural to think that the top license would show proficiency but it doesn't. After a few years many lose the code. Code is like riding a bicycle, once you really learn it, it comes back quickly.

Let's compare English to CW. English has 44 phonemes or phonics. These are sounds, that in various combinations make up our words. CW has only 2 sounds that make up all words. English has about 50,000 words in common speech and about 10 times that totally. Ham radio CW has about 100 words in common use, but of course you may use the whole English language in rag chewing. Many English words have more than 4 letters, even 10 or more. Of the "100" CW words, the largest is only 4 letters. There is no punctuation in any "spoken" language, as that is only for written words. English rules for spelling and grammar do not apply to CW. As with any spoken language there is no upper or lower case.

What are the requirements for learning this simple language? Anybody who can communicate in any language can learn CW. What about the person who is tone deaf? Tone deaf hams lose their ability to understand speech long before CW. This is because it's possible to adjust the CW pitch to a tone that is still within range. Some hams are only on CW because they can't hear speech easily. People who seem to have the easiest time with CW are those with musical ability. In the same way that some people speak slowly and some quickly, the same follows for CW. Virtually everybody can learn 20 wpm, except maybe those with severe learning handicaps. I feel that the former FCC medical exception for code was in most cases in error or fraudulent. Almost any medical condition that would prohibit one from learning the code would also prohibit one from using a ham license.

In CW classes, I have sent CQ at 35 wpm to operators claiming they were capable of only 8 or 10 wpm and asked if anybody could identify it. Typically the answer is "That's CQ, I can copy that at any speed. "Congratulations, you have just proven that you can copy 35 WPM. Now you just need a larger vocabulary!" It might at first sound silly, but it's true. This clue tells us that we need to hear the code the same way that we would eventually expect to use it. The same as any language. Just like an infant learns words that are important to it's life, we should only try to learn words that we will actually use. So let's first learn ham radio words. A conversation, on the air, is called a QSO. A QSO has important characteristics to understand. DX, contest QSOs, and traffic messages are exceptions that are highly specialized. Let's deal with the standard QSO.

The first transmission of a QSO is standardized for the whole world. It conveys only 3 pieces of information, partly as a test of conditions. If one or more of these are lost then little time has been wasted. There is nothing worse than someone sending for 10 minutes and getting nothing. The first 2 of these 3 are designed to convey information that can allow changes to be made to improve the quality of the contact. Over 50% of the words in the first transmission are just as recognizable as CQ. Each of these could be considered as a freebie. Stuff that is so recognizable that you just know what is coming along next. What really happens is that this easy stuff provides a kind of breathing space and serves to alert you as to what is next.

The first thing sent is the "RST" or signal report. If the received report is poor then something must be done to improve the signal. Two things can possibly be done, increase the power or change the antenna. This may be the time to warm up the linear amplifier. The second thing sent is the QTH, or location. This may tell you the direction to turn the antenna. If you increase power or turn the antenna, or both, then you can be sure that the other station will hear you better. The third is the name and it is for politeness.

First, the signal report, RST is a number of only three digits. The "R" is for readability and is usually a 5, sometimes a 4 and rarely a 3. The "S" is for strength and can be anything between 1 and 9. Usually it's 5 or higher. The "T" is for tone and is always a 9, due to today's modern equipment and clean commercial power. We are going to hear the letters RST, which, like CQ, we can copy at any speed. Then we get a 4 or 5 and now it's time to wake up because the only important thing is about to come along. It's the "S" and in this example a 7, so write it down, now the useless "T" a 9, don't write it. Then here comes the whole thing again. A typical report would look like this "RST 579 RST 579" and you are only looking for the 7. A total of 12 "things" have been sent and you only need one, maybe two of them. You even had a good idea what it might be. Now isn't that easy?

Second, the QTH, or location, is tougher as it is something that you will actually need to copy. All is not lost because nobody has gone to jail for not getting it the first time. To ask for a repeat, just say "QTH ?" On the FCC test you must copy it. More about this later.

Third, is the name, and this is simple. Most CW operators have shortened any long name to 4 letters or less. To ask for a repeat just say "name ?" If you never get the name then just fall back to the old standby "OM," meaning "old man." This must be the only hobby where you compliment someone by calling them old.

The second transmission isn't as formal, but may include a description of the station, the weather, your age and profession. Now you are not hearing many of the 100 words, but real information proceeded by one of the 100, such as "wx cool es cldy." This translates to "My weather is cool and cloudy." the term "wx" alerts you to words about weather. Additional transmissions would branch off into mutual interests and follow no pattern. Now you must actually copy CW or say "73" and move on to another QSO. Many DX stations do this, as they have limited English and can only copy the basic QSO.

What are these 100 words in Morse Co?

The first 26 are our alphabet. Sometimes one letter has a meaning that is one or more words. The letter "R" means "I have received all that you have sent." The letter "C" means "yes." The letter "K" means "It is your turn to transmit". The next 10 are the digits from 0 to 9. Another 10 are the Q signals. About 10 "Q" signals are all that we really use so forget that long list. Most of the rest of the 100 words are only 2 or 3 letters long ie. "hw?" this means "How well did you copy?" The longest word is "name" and it has no secret meaning.

Many students seem to be thrown by the punctuation. The FCC test requires that you be able to answer questions about the message sent. Failure to get punctuation can't possibly cause you miss a question on the test. For example, "My QTH is Galt, CA." and you have missed a period or comma. How can you not get the answer to the question? The testing people might use that phrase, but on the air it would be "QTH Galt CA Galt CA." Even with that highly abbreviated form, you should be able to answer the question. Now you spot the question mark and the slant bar. They are wonderful ways to say a lot by sending a little. The "?" means "here is a question." "Name ?" means "Please tell me your name." The slant bar, or fraction bar, is used in a call sign as in this example. "JT1/W6REC" means "I am a portable station in Mongolia (JT) and my home call is W6REC." Don't you think learning the little slant bar is a good trade off? These two are used, not as punctuation, but instead, as a group of several words. The FCC test won't be about an easy "first transmission" because it's impossible to ask 10 questions from the 3 bits of information in the standard QSO. This test will include information that would typically come from 2 or 3 transmissions, so that 10 questions can be asked. The good news is that you will have learned at the speed of fluency and the information that comes at you at 13-20 WPM sounds really slow and is easily copied.

A REVIEW OF TRADITIONAL METHODS

In order to analyze existing learning methods we should consider our goals. We need conversational language. We are doing the same thing as sitting around the living room and chatting. Nobody is taking notes or transcribing, as in a business conference or legal proceeding. If the casual conversation turns technical or to some specialty then our rate of speaking and understanding will slow down. The same thing happens in any language, as well as in CW.

1. The Farnsworth method.

This method makes use of the fact that the brain can decipher the dits and dahs at a high speed. The letters are sent at a fast speed and lots of space is left between each one so that the brain has increased recognition time. Some of the code tapes use 22 wpm for the letter speed and only shorten up the space to increase the speed. The Farnsworth method was first described in the late 50s and has become a standard way to learn CW.

2. Military

The military method is sometimes touted as "the way." The purpose of this form of communication was to provide written copy to another person. The person "copying" the code would hear a symbol and immediately type it. The sound triggered a motor response, but no understanding. The information received was 5 letter code groups, which included digits, and was unreadable until someone decoded it. Not very suitable for our use.

3. Morse Code Tapes.

Thousands of people have studied code tapes and have learned CW this way. There are several problems with this method. Many students report that they eventually memorize the tape and aren't actually learning code. Some were not even aware that this was happening. In order to reduce this memorizing, some tricks have been developed, such as spelling the words backwards. To copy this it's necessary to write it all down. Imagine hearing a language backwards in order to learn it forwards. None of the tapes that I have heard are concentrating on the basic vocabulary, or what I call the "100 words." The quality of some tapes are very poor. To compare this to learning Spanish, it would be similar to hearing poorly spoken Spanish, about an unknown subject, in a crowded and noisy room. Does that sound easy? Tapes do have lots of potential. The tapes just need the right words recorded. Use the tendency to memorize as an advantage and just hear the basic 100, randomly, at the speed of fluency.

4. Morse Code computer programs.

I have reviewed a few of the programs but haven't yet found one that is designed to do this job. The first problem is that all of them require one to type. When one learns Spanish, does one type something to indicate understanding? We have no need to type messages, only understand the meanings of sounds. Why respond to a meaningful sound with a motor movement? This will only slow one down. Typing ability shouldn't be a prerequisite for learning CW.

What should a computer program do? What we need is Farnsworth words. The whole word sent quickly, at the speed of fluency, and then a big space. At least two of the popular programs can be fooled into doing this. Use the part of the program that will send a text of your choice. Make a text file of "words" with lots of spaces added between.

5. On the air practice.

This method is divided into two parts. Listening to code practice stations and entering into actual contacts. The ARRL sends code practice on several bands and at different speeds. The code is perfect and is text from QST magazine, so at least it is about amateur radio subjects. The first disadvantage is that you must contend with QRM, (interference) QRN, (static) and QSB (fading). Learn the code, then you can learn to contend with the real world and its distractions. The second disadvantage is that you must have the equipment to receive the signals and know how to use it. CW signals that are poorly tuned, are hard to copy.

The third disadvantage is that one would never send these words on the air. One private party sends code practice on 40 meters. This code is text from the Bible. To learn Spanish, would you listen to tapes of a Spanish translation of the Bible? Maybe, if you plan to be a missionary, in a Spanish speaking country and plan to give sermons in code. Is it any wonder that code is a challenge to learn this way? Having actual contacts on the air is a commonly advised method, and it will work, but has some inherent problems. All three of the disadvantages mentioned above for "on the air" code practice apply here too. In addition, the code heard on the air is far from perfect. Perfect code is much easier to copy, and this is especially important for the new student. Another disadvantage is that the student must also learn the necessary motor skills of sending CW. One aspect of "on the air" learning is both an advantage and a disadvantage. The advantage is that when a someone is trying to communicate with you, you have a vested interest and probably greater concentration. After all, if we miss what the computer or tape has sent we can just rewind it. You might be so interested to hear what somebody is saying to you that you really try. Or you might just freeze up and get nothing. Your personality determines how you respond to the challenge. One big advantage to "on the air" practice is that you learn the equipment, propagation, make friends and get practice doing what you want to do anyway, Do you really want to communicate using code, or just pass the test?

The disadvantage is that you may learn poor procedures, use a lot of time and won't hear fast relevant code. The most efficient method is to hear fast, correct code from the start. I feel that current novice habits are so far from the world standard that bad habits are guaranteed to be learned. Why learn poor habits and then hope to relearn good ones? More about this later.

LEARNING CW

Here is the sequence to learning CW the most efficient way. Second, learn to send the code with a paddle and electronic keyer combination. Third, learn to copy off the air. Began sending as soon as possible.

Hear are the three ways to hear this 100 words.

1. Learn to copy the 100 words by hearing them in perfect code. A computer can send perfect code from text files made up from these 100 words. None of the programs I have seen are intended to do this. At least one of the popular shareware programs can be made to do this. The trick is to enter enough spaces between the words to give the time you need. As you improve, edit the file and reduce the spaces between words. Make an audio tape of these files for use away from the computer. Find a friend who is willing to send the words to you.

I recommend that a certain sequence be used for the alphabet. This may not work for all, but give it a try.

EISH5

TMO0, that's the letter O and the number zero

AWJ1

NDB6

AUV4

Notice that the same letter comes up in more than one sequence. It can fit into more than one logical order. Practice the EISH5 until it's easy, then go on to the next sequence. Many letters don't fit any order, just tough it out.

2. Learn to send. Acquire a paddle and electronic keyer combination to practice sending. Do not start with a straight key. Send the 100 words in any order, quickly. One of the daily drills I recommend is to send the alphabet as quickly as possibly. Keep track of the number of seconds required. Ignore the mistakes, they will disappear as you get better. One of the things we hear from beginners is that they can send faster than they can receive. High speed operators report that they can copy faster than they can send. I have heard two theories to explain this. As you send CW, your brain has knowledge of what's coming along. This advance warning gives time for the brain to remember the dits and dahs. In receiving there is no warning and the brain must put it into context. The other theory is that different parts of the brain are involved in sending and receiving. If that is true then it follows that the sending part can then teach the receiving part, and it works, to some extent. The high speed operator is limited, in sending, by the speed of the motor functions. In my case, the brain runs out of gas in the 50 wpm range for receive and my hand gets pretty sloppy at 35 wpm. I am ambidextrous, or mixed handed in many activities. I write left handed and learned to send right handed. I am lucky, as I can do both, to some extent, simultaneously. Why don't you learn to send with your other hand?

3. Learn to receive and send by making contacts on the air. Most of the code is far from perfect, but this is real life. One helpful thing that you can do for your first QSOs is to write the information that you expect to send.

Typical first transmission.

________ De W6REC

RST 599 599

QTH Galt CA Galt CA

Name Duane Duane

Hw Cpy?

De W6REC

Typical second transmission

__________ De W6REC

RR Tom

Rig TS850

Ant 3 el Yagi up 80 feet

Age 50 50 yrs

Wx sunny es warm

De W6REC

The blank spaces represent the other ham's call sign. You can fill it in and then you have the first transmission ready for sending from your paper. After the first few QSOs the tension will reduce and you won't need the paper. Notice that I didn't use the K at the end of the transmission to mean "It is your turn to transmit." I recommend that you don't use this because it's going out of style. It is still used by some operators but actually it's rather useless.

When you send information, the call signs and then stop sending, most people will figure out that it's their turn, so why tell them?

Suppose you get so nervous that you copy nothing and have no reason to think you can save it? In the worst case you can just leave and do nothing, nobody is watching. The other station can assume that you had a phone call or conditions changed. Or just wait until the person stops sending and send your "panic" message. Make this message up ahead of time and keep it ready. It could say something like this.

DE W6REC

Sri QRM

No cpy

Tu QSO 73

De W6REC SK.

Or it could say the truth, "I can not copy I am going to kill myself 73.

BASIC 100 WORDS

This list can be easily debated as to whether it is too long or too short. The list I have used for years has grown and shrunk and currently is about 97 "words".

?-To indicate that a question has been asked QTH? means "Where do you live?"

/- Shows portable operation

(8 DITS)-Mistake, Start the word over.. Advanced operators abbreviate this with 2 dits, widely spaced, "E E." The most advanced operators tend to ignore their mistakes, as they know that the copier will fix it mentally. We do this automatically in casual speech.

SPECIAL WORDS

BT-Pause, similar to the verbal "Ahhh" that just fills in.

__

AS-Standby for a few seconds

__

AR-End of transmission, no longer in general use

The line over the letters is used to indicate that the letters are run together with no spacing.

FUNNY NUMBERS

These "numbers" are used in some DX and contest QSOs and are included here because you may come across them and wonder. It's another example of a short cut.

N-The abbreviation for the number 9. This is derived from the last two parts of the 9, not from the first letter of the word "nine." Example, "RST 5NN" FOR 599

T-The abbreviation for zero, in the days before the electronic keyer it was a long dah and can still be heard occasionally today by operators using a "bug".

A-The abbreviation for the number one, in this case its the first 2 parts of the digit.

Learn CW using the Koch Training

Amateur license restructuring is here. You no longer need to pass a 13- or 20-word-per-minute (wpm) test to gain full operating privileges. Passing a 5-wpm test gets you everything. However, there are good reasons why you should do more than that. Having a level of Morse proficiency that is of real use on the air, meaning that you can copy at 12-13 wpm or more, will add immeasurably to your enjoyment of Amateur Radio.

Such rewarding HF activities as DXing, contesting and QRP operating still rely heavily on CW. Thousands of hams enjoy CW for its own appeal as a relaxing mode different from most other means of communication. And even on VHF and higher frequencies, you'll find that exciting activities such as Moonbounce and weak-signal work still require Morse skills for full participation.

The pressure to reduce the code-speed requirements came from the widespread perception that getting to 13 or 20 wpm is a nearly imsurmountable barrier. That perception is wrong. For little more investment of time than it takes to pass the 5-wpm test, you can gain real, higher-speed code proficiency that will enhance your enjoyment of the hobby.

Most of what you've been told about learning Morse Code is wrong -- dead wrong. Amateur radio operators traditionally have used the slowest, most frustrating, most painful and least effective techniques possible for gaining code proficiency.

You can gain real code proficiency. You can do it in a reasonable amount of time and with a minimum of frustration and pain. In order to do so, you must approach code training from a different perspective and use different techniques from those common among amateurs for the past half century.

Learn Morse Code using the Koch Method

It will require work (just as it does to get to 5 wpm). You will have to commit yourself to at least one 15-30 minute training session every day until you reach your goal. You may succeed in a month or in several months; individuals differ greatly. Without this committment, however, you may as well not bother.

So what's new here? By using a code training method devised by the German psychologist Ludwig Koch some 60 years ago, you will progress as quickly as you possibly can, with ample reinforcement and little frustration. By understanding this method and how it builds your code proficiency, you will know why you have to spend time practicing and you'll be able to make a reasonable prediction of how long the total effort will require.

We're going to start on your road to success by throwing some time-honored ham-radio traditions onto the trash heap where they belong. These are:

  • Slow (5 wpm) code -- It ought to be illegal to teach anyone code at 5 wpm. Every minute spent toying with 5 wpm code is irrevocably wasted. In addition, as we'll see later, starting with slow code is a virtually-guaranteed path to frustration and quitting. Morse at 5 wpm and Morse at 15 or 20 wpm are completely different critters, and you don't want to waste time on the wrong one.

  • Charts, mnemonics, musical cues and other "memory aids" -- These things make you think about what you're doing while trying to copy code. That is deadly to proficient copying.

  • Code tapes -- In very short order, and unconsciously, you'll memorize the tape. This will lull you into false confidence in your ability. That false confidence will be quickly shattered when you hear transmitted text that you haven't memorized.

  • Copying QSOs off the air -- You don't know the speed of code you find on the bands, and much code on the air is pretty badly sent. All this makes it useless for training purposes. Formal code-practice sessions, such as those on W1AW, are OK, however.

Now that you know what you're not going to do, let's start examining just how you can best gain code proficiency.

The Mechanics: Just what is code training, anyhow?

Go to the shack of a veteran CW operator, or visit the CW station at a club Field Day operation. Watch people copy and send code at 30 to 35 wpm. You'll notice they're pretty relaxed about it; they're not sweating each character as it comes out of the speaker and they're not racking their brains to "figure out" what's being sent. Code has become second nature to them.

That's the key to code proficiency. Copying code must be a thought-free process. When you hear a character, you should know, without thinking, what it is. It should be a reflex. In fact, copying above about 10 wpm can only be done by reflex. Above that speed, thought processes are too slow to succeed.

That's why slow code is a deadly trap, and why traditional amateur methods of code training are so painful and frustrating. Most hams are told to memorize all the characters, then start building their speed. When you do it this way, you build a "lookup table" in your brain, comparing each character you hear with those in the lookup table until you find a match. This process shuts down from overload at about 10 wpm. That's why people experience a "plateau" at 10 wpm, and don't see any progress for weeks or months.

Those who finally get over that "hump" and progress beyond 10 wpm do so because, through constant practice, they have begun to copy code by reflex instead of by thought. They are the lucky ones; this 10 wpm barrier is where many folks give up out of frustration.

Code training, then, should completely bypass the lookup-table phase and begin by building copying proficiency as a reflex. This was recognized in the 1930s by the German psychologist Ludwig Koch, who devised the most efficient method known for Morse training. It's his method, and how you can use it, that we're going to examine in detail.

Morse Training by the Koch Method

Koch's method is a simple, direct way of building reflexes. However, it requires either a computer and Morse software or a personal trainer. That's why it was overlooked for so many years. Now that computers are commonplace, it should become the standard Morse training method. Here's how it works:

You start out by setting up your computer (or a microprocessor-based code tutor machine) to send you Morse characters at 20 wpm and at an overall sending speed of at least 15 wpm. You then get out your paper and pencil and have the machine start sending -- but only two characters. That's right, for your first sessions, you'll only have two choices. Copy on paper for five minutes, then stop the machine and compare what you copied with what the machine sent. Count characters and calculate your percentage of correct copy.

(Here is a GREAT Koch-method training software package: G4FON's CW Trainer from G4FON, Ray Goff. NOTE: I HIGHLY RECOMMEND THIS TRAINING METHOD - Tomas, NW7US)

(See Setting SuperMorse to do Koch for tips on using the Koch method with SuperMorse.)

If your score is 90 percent or better -- congratulations! You just learned your first two characters, and, importantly, you learned them at full speed. You'll never have to learn them over again. If you didn't make 90 percent, practice some more. As soon as you can copy the first two characters with 90 percent accuracy, add a third character to your practice. Your accuracy will drop as you work on assimilating the new character, but it will rise again to 90 percent or better. Then you add the fourth character, and so on.

This method does not allow you to build that lookup table in your brain. To copy at full speed, you must build the reflexes in order to achieve 90 percent accuracy. And that's what you're spending your time doing -- building reflexes. Think of it as a parallel to perfecting a tennis swing or mastering a gymnastic routine; you're practicing until you get it right. The Koch method of building code proficiency character-by-character is similar to standard methods of teaching touch typing, another skill that must be reflexive.

This is a very individual method of training -- you progress at your own best speed, and spend only the time required to gain each new character. This means that you will waste no time in reaching your goal.

How much time is required? That will depend on the individual. Koch himself, with hand-picked students, got a group to master 12 wpm code in a mere 13.5 hours. You probably won't match that, but that's much faster than any other method in the psychological literature. You can get an idea of how long it's going to take after you've mastered a few characters. Keep track of your training sessions (some software will do this for you) and calculate your hours-per-character rate (or characters-per-hour if you're really fast!). That, multiplied by the 43 characters in the amateur Morse test, will give a rough idea of how long it's going to take.

While the Koch method is the fastest method of Morse training, speed alone is not its principal advantage. Its principal advantage, and a major difference from other methods, is that it provides you with constant positive reinforcement. This begins with your realization, after mastering the first two characters, that you can copy code at 15 or 20 wpm, because you just did it. After that, each new character mastered is further proof of your progress. Contrast that to slowly trying to build speed up from 4 or 5 wpm, then hitting the plateau at 10 wpm and seeing no progress for a long time. With the Koch method, frustration is at a minimum.

Constant testing is necessary to ensure that you maximize the effectiveness of the Koch method. You must copy on paper, so you can grade yourself. Remember, if you score 90 percent accuracy or better, add another character. If you score any less than that, try again. By constantly testing yourself on continuous copying of at least five minutes, you know exactly how you're doing and exactly when you should add another character. This results in the fastest progress possible.

Naturally, with the Koch method, you'll be copying random groups of characters, rather than words, until you've mastered the entire character set. If your software allows, make these groups of random length, rather than a constant stream of five-character groups. This will ease the transition from random groups to actual words. Yes, there is a difference in the rhythm and "feel" of words and random groups. Once you've become accustomed to copying words, you should start copying sample QSOs, which are the format of the amateur tests. Pay special attention to callsigns, locations, and numerals; these are the types of things that can form questions on the test.

As you proceed toward your goal, remember that some days are just going to be better than others and some characters will take longer to assimilate than others. You know, however, that you can reach your goal because you've already mastered some characters and proven that copying at full speed is something you can do. Keep in mind that what you're doing is building reflexes, and that takes time. The amount of time you require has nothing to do with your intellegence; it's just how long it takes for characters to "sink in" and become part of your reflexes.

So there it is -- your path to real, useful Morse Code proficiency. After you've used this method, and start enjoying the wonderful world of HF radio, try a few CW QSOs. With Morse code developed as a reflex, you may just find that you really enjoy using it on the air. After all, you've gained proficiency without the frustrating ordeal that most hams have endured for decades. See you on the HF bands!

Questions? They're probably answered in Morse Code: Breaking the Barrier, the author's complete book on code training and CW operating, published by MFJ Enterprises, Inc.

Installing The FT-857 Options

Author: Dave Fifield (AD6A) - dave@ad6a.com

Here are some photos showing the procedure to install the optional filters (and a few showing off the color display), TXCO-9 and DSP-2 to the Yaesu FT-857 rig. There's nothing hard about installing any of these modifications. The instructions in the Yaesu manual are fairly comprehensive and the menu options to select them are easy to get right.

Make sure to get the filters and TXCO-9 round the right way. As with it's big brother, the FT-897, it's worth noting that the FT-857 optional filters are labeled with different part numbers than are on the boxes they come in! The YF-122S is marked XF-119SN and the YF-122CN is marked XF-119CN.

The schematic of the FT-857 is almost identical to the FT-897. Both rigs support the ATAS-100 and ATAS-120 antennas with every option you can think of for diplexer/separate antenna use. Please email me if you have any questions or comments. Click on any of the pictures to see it in full detail. Hover your mouse over the pictures to see my comments on it.

The FT-857 opened up ready for the options to be added. The standard oscillator - tucked away in the corner by the rear heatsink. The FIL-1 and FIL-2 optional filter positions - pretty obvious!

The 2.3KHz SSB filter installed. The TXCO-9 option installed. The 300Hz CW filter installed.

The DSP-2 board is fitted vertically - the connector is all that holds it in place, but it seems mechanically rigid enough. The DSP-2 option board - vertically mounted. The other side of the rig - the power amps and filters/switching. Note the two internally mounted fans that blow air over both the top and bottom PCBs in the rig - nice design feature!

The rear panel - note the trend towards no direct labeling - I don't like this! The label showing the rear panel connections is on the underside of the rig... The cooling air intake - behind the front panel, but fully exposed when you remote mount the head - good design IMO!

Well, I tried to capture some of the colors - this is meant to be green, but the digital camera doesn't seem to think so! ...and this is meant to be bright red....

...and this is meant to be blue - oh, it is!..... ...and finally, purple (violet, whatever). There are 32 shades of these basic colors - coolio!

MARS mod of the FT-857 (US version)

FT-857 (US version)
Modification for TX:
1.8-56MHz, 137-164MHz, 420-470MHz
  1. Remove the seven screws affixing the top panel of the transceiver, and gently lift it upward.

  2. Carefully remove the small 2-pin speaker plug from the left rear corner of the transceiver interior then remove the top case and set it aside for the moment.

  3. Locate the nine jumpers about 2" from the front edge of the main unit and about 3/4" from the left edge. For 144/430MHz expansion only, remove the jumper at JP1002, leaving the other jumpers alone. For complete expansion per the above listing, place jumpers at JP1007/1008/1009, and remove the jumpers at JP1001/1002/1003/1004/1005 (leave the jumper at JP1006 in place). NOTE THE UNUSUAL SEQUENCE FOR THE NUMBERING.

  4. Replace the top panel; don't forget to re-connect the speaker lead removed in step 2.

  5. With the transceiver off, press and hold in the [F] and [V/M] keys; while holding them in, turn the radio on. Modification is now complete.

Yaesu VX-7R Mods

———- Transmit Mod VX7 ——————————————————————————————————————
Remove the battery pack.

Remove the sticker/cover seal for the pressure sensing unit (SU-1), in the battery compartment. This is the black strip above cellular warning label and is where the SU-1 option goes.

Locate row of eight jumpers. They are numbered.

For Mars/Cap, remove solder jumper 5.

For Freeband, remove solder jumper 4 and 5.

Reset microprocessor. (Press and hold in the 4, band, and v/m keys while turning the radio on.

You can do all of this or you can do a soft-mod using VX-7 Commander which can be found at KC8UNJ.com. It’s free software and all you need is a programming cable and adapter. This is the route that I took when modifying my VX-7 since it is extremely easy to do, and just as easy to return the radio to it’s original state.
If something should happen to KC8UNJ’s server here are the files on my server.
Download VX7 Commander Version 1.3.4
Full Installer 2.4MB zip

Download VX7 Commander Version 1.3.4
Full split into floppy-sized chunks 2.4MB zip

Download the VX-7 Commander 1.3.4 update
only if you ALREADY HAVE VX-7 COMMANDER 1.3.3 INSTALLED

Download VX-7 Commander Japanese Direct Input Version 1.3.3
(Requires Japanese Windows)

ENJOY
TX Frequencies:
Freeband: 40-224.995Mhz and 300-579.995Mhz
Mars/Cap: 50Mhz-54Mhz, 140Mhz-174Mhz, 222Mhz-225Mhz, and 420Mhz-470Mhz.

—————————————————————————————————————————————————————————-——- Free Band Mod VX7 (Europe)—————————————————————————————————
If you have a vx-7 europe version here is how to modify.

Remove the battery pack.

Remove the sticker/cover seal for the pressure sensing unit (SU-1), in the battery compartment. This is the black strip above cellular warning label and is where the SU-1 option goes.

Locate row of eight jumpers. They are numbered.

For Freeband, remove(Unsolder) all solder jumper exept 3

Reset the transceiver by holding down MON/F + HM/RV + Internet Key and power up the transceiver
This will display the Vertex Standard logo instead of Yaesu. Bear in mind that resetting the transceiver by holding down 4 + BAND + V/M and powering up the transceiver WONT work!

TX Frequencies:
Freeband: 40-224.995Mhz and 300-579.995Mhz

—————————————————————————————————————————————————————————-——- Another European VX-7 TX MOD ———————————————————————————————-
I own the B1 European version (Label outside the box indicates DST:EXP / TYP:B1). Prior to any modifications the transceivers jumpers was soldered on positions 2,4,5,7 (factory setting) and the unit was capable of working on the following frequencies ONLY!

50-52MHz (RX ONLY, NO TX Possible!)
144-146MHz (RX/TX)
430-440MHz (RX/TX) Reception was NOT possible anywhere outside these limits!

In order to modify it you should:

Unsolder every jumper

Reset the transceiver by holding down MON/F + HM/RV + Internet Key and power up the transceiver
This will display the Vertex Standard logo instead of Yaesu. Bear in mind that resetting the transceiver by holding down 4 + BAND + V/M and powering up the transceiver WONT work! It will just enter a curious set up:

RX on all bands

No WX Channels

Menu Item Misc Setup 20: BEAT SQL (Instead of WX Alert)

Menu Item Special Memory 6: JR (Instead of Marine)

Menu Item Misc Setup 17: Japanese (Instead of English)

Transmittion on 50-54MHz, 137-174MHz, 420-470MHz
After the aforementioned modification you will have continues RX coverage from 504KHz up to 999MHz (including analogue cellular frequencies – NO GAPS!)

—————————————————————————————————————————————————————————-——- More on the European Version————————————————————————————————-
