The PRECISION CW Download Page

You probably have come here because you were looking for software. Software to train reading Morse code, software to train Morse keying or software to run CW mode or even COHERENT CW mode on your amateur radio equipment from your PC.

Below you find a list of downloadable software, free of charge. Just select what you are looking for.

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 helps you to train your Morse/CW keying abilities.
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 - with just a small one-resistor-interface and a serial RS232/COM interface - connect your key directly to the PC.
The program will show you what you are keying, mark and space, dots and dashes. It will even try to decode the Morse characters you have formed.

New: much improved and better handling of serial RS232/COM interfaces


Yes, yet another Morse/CW training program.
I have used this one (and its earlier versions) for teaching to read Morse code with much success since 1993.
The latest version V 6.0 now is a genuine Windows program. It supports random characters and variable speed. Of course, the Farnsworth training method is supported. This program has just been adapted for Windows 10 and will still see some improvements in the future.

PCW Tutor V 4.6 for DOS

PCW TUTOR V 4.6, the last version designed for DOS, needs a PC sound card to support morse output and can use random words from an editable list. This final DOS version runs on DOS computers as well as on PCs running Windows up to Windows XP SP3.
This version is still available in case you want to use a computer running DOS.

PRECISION CW for Coherent CW (CCW)

Precision CW V 2.4

This is the last version of the PRECISION CW program for receiving and sending COHERENT CW.
This version can run under standard DOS or in a DOS box of Windows, but it does no longer accept the VE2IQ interface. Data input is only via a PC soundcard.
Keying output is still accomplished via one line of one of the COM serial interfaces. Some minor bugs have been fixed.
The minimum PC requirements are a '286 processor with at least 24 MHz clock..

No download, only available upon special request
