You probably have come here because you are looking for
Morse Code software. Two different types of training software are available on this web site:
Precision CW Fistcheck was designed to help you train your
Precision CW Tutor was designed to help you train your
And you can also find some information on the COHERENT CW mode.
The software you find below is believed to be safe. You can download and use it free of charge. Just select what you are looking for.
Special thanks for numerous discussions, ideas, suggestions, and thorough testing and bug reports go to a number of radio amateurs, especially to Bill, WA2NFN, Paul, KW1L, Bob, WO6W and Derek, K6MDG.
If you have problems with downloading or any questions related to the software, you should send me an EMail. 73, Ernst DJ7HS
This piece of software allows you to train your ability to send International Morse Code.
Just connect your straight or semiautomatic key to a Morse buzzer and connect the buzzer's output to the audio input of your PC or laptop.
Or you connect your key directly to the PC, either with a specially prepared mouse, or with just a small one-resistor-interface and a serial RS232/COM interface.
The program will show you what you are keying, mark and space, dots and dashes. And it will try to decode the Morse characters you have formed.
A page with FAQ and help information on PCW Fistcheck V 3.8 is available here.
And here is an example, where the Morse characters "PSEK" have been keyed with a straight key. Pressing F9 would right now give an audible playback of this sequence with exactly the same timing.

Precision CW Tutor or PCW Tutor allows you to train your ability to read International Morse Code by ear. You may use Precision CW Tutor as a general purpose Morse keyer, and for many more applications.
I myself have used this software (and its earlier versions) for
teaching to read Morse code with much success since 1993.
If you are running a Morse code class, you can at any time use PCW Tutor as a Morse keyer, just like you would use a straight or semiautomatic key. The main feature though is that randomly generated Morse characters, or randomly created words from a loaded list, even whole phrases consisting of several words, or randomly created Q-codes can be produced. And this is equally helpful in a Morse code class or for training all by yourself. Morse speed can be easily changed on the fly or automatically increased within a session. And of course, the Farnsworth training method is supported, which uses a constant fixed speed for the single characters and longer pauses in between to have some "thinking time".

And here is an example of a session with 150 randomly picked Morse characters:

This paper by Ray Petit in QST of September 1975 seems to be one of the earliest documents dealing with the then new "coherent" mode for CW.
These notes have been prepared by Peter Lumb, G3IRM, in 1995. They give you some idea how COHERENT CW operates.
This document gives you some insight into the theory behind COHERENT CW.
