New: now adapted and tested for Windows 10


This piece of software helps you to train your 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.
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: now adapted and tested for Windows 10


Yes, yet another 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 5 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.
The last version designed for DOS, PCW TUTOR V 4.6, supports PC sound card morse output and random words from an editable list. It also remembers the settings from a previous session.
This latest DOS version runs on DOS computers as well as on PCs running Windows (latest Version tested is Windows XP SP3). In Windows there may be occasionally a timing error that results in a somewhat corrupted Morse character.

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
