When I returned to Amateur Radio my CW was decidedly rusty. What I felt I needed was a CW Trainer to get my speed back. I looked around the Web and found an article by Dave Finley N1IRZ on a method of CW training developed by a German psychologist called Ludwig Koch back in the 1930's.
Reading though Dave's article, I decided that it all made a lot of sense. Basically you start off learning the code at the speed you would like to achieve. Unlike the Farnsworth method which seeks to reduce the gap between the letters as you become more efficient, Koch came up with the idea that you should start off just learning two letters at full speed and add an additional letter once you reach 90% proficiency until you have mastered them all. Since you are only learning one new letter or figure at a time, your frustration is significantly reduced.
Dave Finley gave a suggested order for learning the letters and figures and recommended a programme called Super Morse to use as a trainer. I quickly realised that Super Morse offered more features than were required to learn Morse by the Koch method and decided to write my own programme orientated towards the Koch method.
Positive feedback from users of the software make it clear that the Koch method is a very effective way of both learning Morse and also improving your Morse skills.
Reporting problemsIf you experience a problem with the Morse trainer, contact me at the email address shown to the left of this screen. When reporting a problem time can be saved by sending me the following details:
Version 2.4.0 released 11 February 2002, added the characters sent display - thanks to Jay, AJ4AY for the suggestion.
Version 2.6.0 released 21 February 2002, added simulated chirp to the signal.
Version 3.1.0 released 28 February 2002, added a file send facility - see the new readme file for details.
Version 3.2.1 released 2 March 2002, added a common words file and display control - thanks to Jim KG4LDY, N0HFF and Dave KB2TQX.
Version 3.2.3 released 4 March 2002, changed the maximum session duration to 1 hour at the suggestion of Mike, AC4NS
Version 3.3.0 released 25 May 2002, added a user definable delay between clicking Start and the Morse starting at the suggestion of Chris, NCØS
Version 3.4.0 released 12 June 2002, added presetable inter-character delay. This is not in keeping with the Koch method and I would advise not using it if you are aiming at a code speed of 12 WPM or more, but for folks looking to pass a 5 WPM test to get on the air, it may prove invaluable.
15 June 2002 - whoops, gremlin attack during last update, I transferred version 3.3 again. Version 3.4.0 is now available for download.
29 June 2002 - added David Gwillim's software for checking your score.
Version 3.4.4 released 12 July 2002 with a fix to some sound problems which creep in if you run at the reduced code speeds. This problem appears as appears as clicks and also off pitch tones. Thanks to Gerry, W2GER for pointing this out and helping to fix it.
12 July 2002 - David Gwillim has also been busy updating his KochRx programme so that you no longer need to 'Copy and Paste' the text from my application in order to check your results.
Version 4.0.3 released 2 October 2002 - with new features and added ease of use.
Version 4.2.0 released 5 November 2002 - Fixed a couple of bugs in the display, added word by word reveal of the Common Words file and added the option to make the Morse sound as though is being sent from a straight key.
Version 5.4.0 released 14 May 2003 - Fixed a couple of bugs in the display and use of defined characters. Added a local QRM generator which transmits Morse slightly off frequency. Added additional steps in the Farnsworth setup and fixed a long standing bug in the random number generator.
Version 5.4.5 released 16 July 2003 - Fixed a couple of bugs in the display and use of defined characters. You can now successfully display the user defined Prosigns! There was also a lockup situation which occurred if you rapidly clicked Stop then Start which should be fixed in this release.
Version 6.0.8 released 27 December 2003 - Finally, having promised an update for some time. Thanks to various people who have helped in debugging this version, including Kevin KI4DEF. There is now a special 'Sample QSO' button which becomes active after you have learned all the characters. Prosigns have been improved, now you can have triple letter prosigns! There are also a number of bug fixes.
Version 6.0.11 released 15 February 2004 - Fixed a bug which did not display the words correctly if you delayed the display when listening to Common Words. Added extra code so that all settings are now saved at shutdown and loaded on restart.
Version 7.0.6 released 15 November 2004 - A slew of new features including speed and pitch dither, a resizeable window and speed changing on the fly.
Version 7.0.7 released 20 November 2004 - Whoops, XP got me and the main window does not display correctly on XP, so download this version which corrects the problem.
Version 8.1.3 released 26 March 2005 - New version which includes the option to directly record MP3 audio files and includes other useful additions.
Version 9.1.4 released 25 October 2006 - New visual style, enhanced file handling and general bug fixes. Size and position saved at shutdown.
Version 9.1.5 released 30 October 2006 - Bug fix; wanted characters not saved correctly and some typo's in the text...
Version 9.1.7 released 12 December 2006 - Bug fix; possible fix for MP3 problems and not playing out word files correctly...
Keep checking back for further updates!
