Get on the Air with HF Digital. ARRL Inc. Andrew Barron. Antenna Physics: An Introduction. Grounding and Bonding for the Radio Amateur. Latest updates What's new in version 2. Developer info apps kg9e. Product description This app will train you to hear and send Morse code at 25 WPM using an approach very similar to the Koch method. In this app you learn first the vowels, starting with "a", then alphabetically the letters and ordinally the numbers. As you gain more experience copying Morse code, you will begin to recognize short strings of characters such as "CQ", "73", "Tu", "Tnx", "HiHi", "", "Wx", and the numerous abbreviations, Q-codes and CW prosigns.
For learning the sounds of the characters you are presented with a game-like interface using a QWERTY keypad or the Default keypad, depending upon your choice. A character is played in Morse code, and you must tap the matching character on the keypad.
Note that only the characters you have learned will be enabled. The game is very easy at first as you only have the letter "a" available to tap, but it quickly gets interesting as you progress and learn more characters. Press and hold any alphanumeric key to hear that character in Morse code without registering a hit or miss.Morse code is a method used in telecommunication to encode text characters as standardized sequences of two different signal durations, called dots and dashes or dits and dahs.
The International Morse Code encodes the 26 English letters A through Z, some non-English letters, the Arabic numerals and a small set of punctuation and procedural signals prosigns. There is no distinction between upper and lower case letters. The dot duration is the basic unit of time measurement in Morse code transmission. The duration of a dash is three times the duration of a dot. Each dot or dash within a character is followed by period of signal absence, called a spaceequal to the dot duration.
The letters of a word are separated by a space of duration equal to three dots, and the words are separated by a space equal to seven dots. Thus the most common letter in English, the letter "E", has the shortest code: a single dot. Because the Morse code elements are specified by proportion rather than specific time durations, the code is usually transmitted at the highest rate that the receiver is capable of decoding.
The Morse code transmission rate speed is specified in groups per minutecommonly referred to as words per minute. Morse code is usually transmitted by on-off keying of an information-carrying medium such as electric current, radio waves, visible light, or sound waves.
Morse code can be memorized, and Morse code signalling in a form perceptible to the human senses, such as sound waves or visible light, can be directly interpreted by persons trained in the skill. Because many non-English natural languages use other than the 26 Roman letters, Morse alphabets have been developed for those languages. In an emergency, Morse code can be generated by improvised methods such as turning a light on and off, tapping on an object or sounding a horn or whistle, making it one of the simplest and most versatile methods of telecommunication.
The most common distress signal is SOS — three dots, three dashes, and three dots — internationally recognized by treaty. Early in the nineteenth century, European experimenters made progress with electrical signaling systems, using a variety of techniques including static electricity and electricity from Voltaic piles producing electrochemical and electromagnetic changes.
Part 1 - Learning The Code
These numerous ingenious experimental designs were precursors to practical telegraphic applications. Pulses of electric current were sent along wires to control an electromagnet in the receiving instrument. Many of the earliest telegraph systems used a single-needle system which gave a very simple and robust instrument. However, it was slow, as the receiving operator had to alternate between looking at the needle and writing down the message.
In Morse code, a deflection of the needle to the left corresponded to a dot and a deflection to the right to a dash. The American artist Samuel F. Morsethe American physicist Joseph Henryand Alfred Vail developed an electrical telegraph system. It needed a method to transmit natural language using only electrical pulses and the silence between them. AroundMorse, therefore, developed an early forerunner to the modern International Morse code.
William Cooke and Charles Wheatstone in Britain developed an electrical telegraph that used electromagnets in its receivers.
They obtained an English patent in June and demonstrated it on the London and Birmingham Railway, making it the first commercial telegraph. Carl Friedrich Gauss and Wilhelm Eduard Weber as well as Carl August von Steinheil used codes with varying word lengths for their telegraphs. InCooke and Wheatstone built a telegraph that printed the letters from a wheel of typefaces struck by a hammer.F a n t a l e g n o
The Morse system for telegraphywhich was first used in aboutwas designed to make indentations on a paper tape when electric currents were received. Morse's original telegraph receiver used a mechanical clockwork to move a paper tape. When an electrical current was received, an electromagnet engaged an armature that pushed a stylus onto the moving paper tape, making an indentation on the tape. When the current was interrupted, a spring retracted the stylus and that portion of the moving tape remained unmarked.
Morse code was developed so that operators could translate the indentations marked on the paper tape into text messages. In his earliest code, Morse had planned to transmit only numerals and to use a codebook to look up each word according to the number which had been sent.This link is listed in our web site directory since Sunday Jun 17and till today " 25WPM Morse code trainer - Android App " has been followed for a total of times.

Forgot password? I'm trying to learn using the Koch Method CW Course with a character speed of 20 wpm and an effective speed of 10 wpm default settings.
However, I'm having a hard time writing down all the characters in time. That is, if I even hesitate on a character for the slightest moment, I get left behind very quickly. So, should I lower the effective speed, and if so, what to? Or is the pressure good for me in the long run? Start with character speed to match effective speed at whichever speed you can manage.
Work your way up from there.Tarkon kauna 72
I watched a you tube video which looked very interesting with lots of advice from a large group of hams about to learn cw in America.
The advice from the teacher was use this software. I amd trying this method. Reason being that the character speed remains same throughout only the wpm alters so you are not re learning every time.
Only a few percent of hams are able to communicate in plain language at 30 wpm. Normal speed is between 12 and 25 wpm. To master CW at 10 wpm si respectble and usable on the bands. Few OMs truly master CW at 20 wpm and up. I find it absurd that absolute beginners use 20 wpm, 30 wpm or more - just because some unknown OM in a forum often beginners themselves says so. Some Danish ham published some time ago on eham. I remember, but I am not sure, that the average speed was 20 wpm.
Please notice, cb, that topic starter tries to start the third time, in learning Morse code proficiency. Agree with "ldeletedl - chairphone". Slower than 20wpm character speed and I end up counting the dits and the dahs, which leads to visualizing the pattern in place of recognizing the sound.
Even at 20wpm character speed I find myself doing some visualization. Now its time to get better at distinguishing runs of three dits from four dits so that I may distinguish V from 4, B from 6, and the related H from 5. If I get those six right each time, my error rate drops from characters per minute in error to depending on the set of random characters sent. Jonathan, don't see what visualisation or counting has to be avoided. I can count dots at 50 wpm.
Doesn't mean I need to step up to 70 wpm? As with the sound hearing that comes with time, why force it? For beginners like me, that means getting from sound of each symbol to a letter, number, punctuation, or prosign.
Hopefully, in the future, I will recognize words and go from sound to words without thinking of letters. Going from sound to a visual to a letter to a word to the meaning of the message has at least one unnecessary step, that of visualization.Forgot Password?

It is learning to co-ordinate ear-to-mind-to-hand. Copying by hand exposes all the senses to what you are hearing, and it is nothing more than listening to and writing down what is being received. An old book on telegraphy described it as "taking dictation" -- at first letter-by-letter, later as word-by-word, etc.Common QSO Phrases 25wpm
That is a good way to think of it. So, hunt up that pencil again.
Most people can learn to copy with a pencil up to about 25 wpm a few can reach 35, rarely 45but above that speed almost everybody needs a typewriter "mill". On a typewriter it may also be done "mechanically" by direct ear-to-typewriter-key transfer without processing it through the letter stage to the typewriter key.
You already know how to write. When you copy by hand, make it easy by writing the way you usually do. For example, don't try to block print unless this is natural and easy.
Likewise, don't try to copy on a typewriter "mill" before you have learned how to touch-type. While most of us would like to know what we are copying as we copy, this isn't necessary. It can become so automatic that we copy something correctly without realizing what we are copying. I usually like to know what I am copying, don't you? People who do these things well do not struggle with them -- they have learned so well that it has become second natural for them.
Here is an interesting example of copying properly:- One night, as I was copying mixed groups in a very relaxed manner, and feeling quite comfortable with the code, I asked my friend if he would speed up to 25 wpm from the 20 wpm he had been sending. He started sending them at 25 wpm, and I was vexed at his misunderstanding, but began to copy anyway, wondering why he was using voice to send these simple data.
What voice? He was sending clear code with letter-number combinations at 25 wpm and I was copying it easily. He had become proficient.Forgot Password? After reading an article in the Wall Street Journal about Chuck Adams, K7QO, who has a fascinating hobby — or two — I decided to contact him and find out the story for myself.
Chuck copies Morse code accurately at words per minute WPMmaking him one of the fastest operators in the world. This is the way world records are done and [also] code tests, [copying] one minute without error out of five minutes of plain text from the hard copy generated.
At high speeds, I grab a typewriter, an electric one. The program has a database of something like 45, radio amateur calls, mostly from contesters. You hear a call and type it into the program. If you get it right, the program sends another call at a faster speed and continues to increase the speed for each correct call.Tv seriale turke
If you miss then the next call is sent at a slower speed. Your score is determined by a number of factors: response time, correct calls or number of characters per call, etc. This program is the most frustrating thing you can do … [and] will drive anyone to drink in a hurry. Chuck plays down his achievement, although he learned code in two evenings using an Instructograph paper tape machine. When the dust was settled and the test over, Chuck had done 12 WPM.
He became interested in very high speeds in his senior year in high school.
I was so angry at the time that I told myself no one would ever do that to me again. So far, so good. As with anything there are always questions and one question that comes to mind is if there is value in sending and receiving code at such high speeds. But it seems almost impossible to get more than the gist of a message, much like speed reading where the text is skimmed.
Chuck disagrees. I will never forget that one. Then the Cuban missile crisis was announced. Use it or lost it. It either consciously or subconsciously gets the individuals counting elements.
This is a killer for code speed. Your mind learns to go through a couple of steps before getting the conversion done, and then you later have to unlearn the sequence. One of the good things about Morse code is that the equipment is so easy to build. We were all poor and a single-tube transmitter crystal-controlled rig crystal-controlled rigs were a requirement for one-year Novices was cheap and easy to build.
Use a wire antenna and a simple key and keyer and you are going like gangbusters. It is much more expensive to do the digital modes when you add in the cost of computer and software, but they are popular because you can sit down at the keyboard and have a mini-Internet on the air and no real concentration is required for long periods of time.
He also puts out a series of books on CD at different Morse code speeds. He started the books almost twenty years ago to get plain text code for his daily practice when the AP and UPI wire services discontinued daily news transmissions via Morse to ships at sea.
