The LARC CW Interest Group - updated 2018-01-24

Welcome to the webpage for LARC members who are interested in learning and using Morse Code, also known as Continuous Wave, or CW for short. Although CW proficiency is no longer required for a Canadian Ham Radio License, it is still a valuable skill, and a very useful mode. In general, you will be able to make more distant contacts, in poorer band conditions using CW, compared to voice.

CW Training Course

LARC is offering a Morse Code training course, which started on January 11, 2018. It's taught by Mitch Powell VE3OT, who teaches in our our Basic License Course, taught Ham Radio at Fanshawe College for over 20 years, and generally qualifies as an expert in many areas of our hobby. If the Basic course is any indication, this course will be both informative and entertaining.

For background information on CW in general, check out these sites:

The course will be based on computer software that uses the Koch method of learning Morse Code. For background information (some of it surprising) on why this is the best way to learn CW, look at this article by Dave Finley, N1IRZ. The computer software enables the student to build reflex responses to the sounds of Morse at high speed and avoids building that lookup table in the brain that makes it impossible to get to high speed. Initially, we will be concentrating entirely on decoding or “copying” audible Morse Code, and will not be transmitting code until well into the course.

Some of the basics that we'll be going over are:

  • Relaxation and visualization.
  • Overcoming your “locking zone”: unleash your unlimited potential.
  • Identifying skill development needs.
  • Choosing the kind, make and model of key best suited for your skills and needs.
  • Key adjustment.
  • Operating a Bug, sideswiper, straight, HST and paddle key.
  • Running like hell: developing QRQ skills.

Getting The Computer Software

The software we'll use is PC software written and supported by Ray Goff, G4FON. The first step is to get the software on your computer.

If you use Windows XP/Vista/7/8 or 10: Download version 9.2.4 by clicking on the following link: Install.exe

You should get a file in your downloads folder called KochMorseTrainer Install.exe that is 977,473 bytes long. Doubleclick on the file to install it, and click in response to all the boring questions, including allowing it to create the new directory. When you start it for the first time, you'll get a pop up window asking you to send a QSL card. You can put this off until later - it doesn't impact the operation of the program.

If you want to use similar software on an Android device (not recommended for course): You can get information from IZ2UUF's site and get his free software on Google Play: IZ2UUF Morse Koch CW I haven't tested this myself, and I note that is is written by a different author, and probably isn't identical to the G4FON PC software.

If you want to use similar software on an Apple IOS device (not recommended for course): I haven't tested these, but they seem to be similar to G4FON:

If you want to use the Koch method from a browser (which will work on PC, MAC, Android, IOS, Linux…) (not recommended for course):

From this point onward, we'll assume that you are using the official G4FON software. The others aren't recommended for this course, and you're on your own if you use them.

David Gwillim, KB2TQX, has created a companion program for G4FON which allows you to enter the text on a keyboard and then cut and paste the output from my software for checking. You can download David's software from here in the form of the file You need to unzip this to create 3 separate files, which should be moved (or copied) to this folder:

C:\Program Files (x86)\G4FON Software\Koch Morse Trainer

The file KochMorseTrainer.exe should already be in this folder, and you may need administrator privileges to copy/move the 3 files. Personally, I'm not a touch typist, so I'm not going to explore this option for now. However, Mike Cook offers this advice to get the add-on to work properly: You have to start the G4FON program from the KB2TQX sub-program, and not have the G4FON program already running.

Setting Up The Software

G4FON iconNow that we have the software installed, it's time to do the set up needed so we can use it. First step is to start the program. The installation process should have created a short cut icon on your desktop that looks like the one on the left. If you can't find it, type G4F into the “Search programs and files” box, and it should appear. In either case, double click on what you've found and the program will start up. As mentioned above, the first time you run it, you'll get a request for a QSL card to be sent to G4FON, but you can defer that until later. Just click on OK and the program will still run.

When the program starts, you will see a window that looks like the following.

Q4FON screen

The number of characters you're working on, item A in the diagram above, should be set to 2 to start

The actual character speed, item B, should be set to 15. This means that the dots and dashes that make up each letter will be short enough that you could fit 15 words into each minute. A word is nominally 5 characters long, with a following space, so 15 words a minute means 15 * (5 1) = 90 characters per second. The good news is that the characters will always sound the same, and you only have to learn the sound pattern once.

The effective code speed, item C, should be set to 3 to start. This means that you will actually be hearing 3 words per minute. The same math gives a need for 18 characters per second at this word rate, so there will be some empty time between the characters. For now, that is, because we're going to crank this number up after we are able to recognize all the characters, and some short words, at 3 words per minute.

Next step is to click on the Setup tab at the top of the screen. a new window will come up with 2 tabs: General Setup, and Morse Character Setup, as shown below. Make sure you're in General Setup, and then raise the Session Length in the lower left corner from the default 5 minutes to 10 minutes. Then click OK in the top right corner, and you'll be back at the main screen.


Congratulations! you're now ready to do the assignments for each class, which are described in the meeting history below.

Once you master the basic alphabet, numbers, and punctuation, it will also send random words or QSOs. Also, the program has the ability to include realistic on-the-air conditions in the code, such as QRN, QSB, QRM, different signal strengths, chirp, pitch dithering, and variable weight. There is a KochMorse group on Yahoo that provides a user forum and support.

Meeting History - Most Recent First

Jan 18, 2018

  • Read the “Zen and the Art of Radiotelegraphy“ book/file if you haven't already. It is very comprehensive and covers a lot of topics.
  • We went over the stages of learning Morse Code, and some of the philosophical perspectives. Moral: stick with it and it will get easier. See handout below.
  • Mitch reviewed the process of setting up and configuring the G4FON software, most of which is outlined higher up on the web page
    • note: you can change the font and size of the characters by right clicking in the open space, and then clicking “select font” at the top of the list that appears.
    • note: if the lower case r's amd m's all run together for you, like they did for me, I suggest you use a capitals-only font. The one I use is: PANTON CAPS, (click the OTF button to the right of PANTON LIGHT CAPS to download. Click here for font installation instructions.)
  • The recommended initial G4FON setup is:
    • Characters ( red A in the diagram above) set to 2
    • Actual Character Speed (WPM) (Red B in diagram above) set to 15
    • Effective Code Speed (WPM) (red C in diagram above) set to 1
    • Session Length Minutes set to 10 ( click Setup in main menu bar, then “General Setup” tab, bottom left corner)
  • We'll be using the audio distribution system in the lab next week - bring your headphones.

Here is the handout as a pdf download file

Jan 11, 2018

Our first meeting on Thursday Jan 11, 2018 had a total of 22 people registered, although 5 didn't make it out to the first class. We saw a video that gave an overview of Morse Code, and visited the lab where we will be using the G4FON software on PCs, and listening to a central audio feed.

Mitch provided a paper handout and I've included all of it's material in this website. I will also attach it as a file in the Resources section. We were also provided with a paper notebook which is to record our practice sessions. (I got one with a pretty pink cover - I'm not worried about anyone stealing it.)

The homework assignment was:

  1. get the G4FON software installed and working on your home computer
  2. set up the software for 15 WPM character speed, and 3 WPM effective code rate, as described above, and 2 character testing
  3. do 2 test sessions per day, of 10 minutes duration, and record your responses and scores for each day on one page of your notebook
  4. bring your notebook to next class
  5. bring a headset with a small 3.5 mm plug on the end to class to plug into a computer and the central sound system

Next meeting is Thursday Jan 18, at the same location.

Post Meeting notes

  • fixed some broken links. Either me, or the Wiki software is a bit buggy. Probably both.
  • added advice from Mike Cook on how to get the add-on module from B2TQX for G4FON to run properly.
  • fixed text flow around screen shots in Chrome browser. (Thought I retired from tech support? <grin>)

More news as it happens.
