One of the most common questions I encounter from hams nowadays is “how do you learn Morse Code?” It's clear that they need more than a simple answer such as “Practice, practice, practice!”
Dr. George Sheehan frequently said that "Each of us is an experiment of one". He meant that while there are general rules to learning new things, each of us has to experiment to find out what works best for him or her. For most things, there is no single "best" way for everyone.
That said, here are 12 tips to learning Morse Code:
1) It used to be that there were two main reasons for radio amateurs to learn Morse Code. The first was to actually use it on the air, while the second was to pass the license tests. The second reason has disappeared in the USA and several other countries.
So it's important to understand what your goal really is: to become a Radio Operator who is skilled in Morse Code. That means learning a set of skills, not just the one or two skills needed to pass a one-time test.
That skillset cannot be learned by reading a book, watching a video, using other modes to talk about them on the air, or participating in online forums. While those things help, they are not the core. The needed skillset can only be learned by doing, and it takes time, practice, and an active involvement on your part.
2) Set up a place to study Morse Code. This doesn't mean it's the only place you study code, just that it's optimized for learning it. A good solid desk or table with no distractions, lots of room to write, good lighting, and a good chair. Source(s) of code (computer, HF receiver, tapes, CDs, etc.), key and oscillator. Headphones are a good idea. I recommend starting out with a straight key, you may decide to go straight to paddles and a keyer. Regardless of what key you decide to use, it needs a good solid base and needs to be adjusted properly.
3) Avoid gimmicks such as CodeQuick and printed charts with dots and dashes on them. Often such systems were designed to help a person learn just enough code to pass the 5 wpm test, but resulted in bad habits that had to be unlearned for practical operating. Morse Code as used on radio is sounds, not printing on a chart or little phrases.
Learning to receive consists of nothing more than learning to associate a certain sound pattern with a certain letter or number. There are only about 41 of them to learn. If you could learn to recognize 41 words in a foreign language, you can almost certainly learn Morse Code.
4) Set aside at least a half-hour EVERY DAY for code practice. Can be a couple of ten- or fifteen minute sessions, but they should add up to at least a half hour every day. That means every single day, not just weekends, holidays, etc. If you can do more than a half-hour some days, great! Do it! But more on one day does not give you an excuse for the next day.
Yes, you may miss a day here and there, because life happens. The trick is to keep such missed days to the absolute minimum.
5) If you can enlist a buddy to learn the code with, or find a class, do it! But do NOT use the class or the buddy as an excuse to miss practice or slow down your learning. The buddy and/or class are a supplement to your study, not the center of it.
6) Download and read "The Art And Skill of Radiotelegraphy". It's free and available from several websites. “Zen and the Art of Radiotelegraphy” is also good. Search out other code-oriented websites, articles, etc. and read what they have to say. But always remember they're not a substitute for practice.
7) Practice both sending and receiving each and every day. Most of your practice time should be spent receiving, but the two help each other. Practice receiving by writing it down and by copying "in your head". I find a pencil and block printing works best for me.8) A combination of the Koch method and Farnsworth spacing is probably optimum for most people. Read up on them, understand and use them – but remember they are tools, not magic. They can make learning the code easier but they will not make it automatic.
9) Discontinue ANYTHING that impairs your ability to concentrate, focus, and learn new stuff. Only doctor-prescribed medications are exempt from this rule; beer is not exempt. Eat right, get enough sleep and enough physical exercise.
10) Put away your microphones, stay off the voice radios - all of them. Besides the automated Morse Code generators, listen to hams actually using code on the air. Copy down what they send. Have Morse Code playing in the background while you do other things (but don’t count that as practice time). Learn how hams actually use code. When you get to the point where you can send and receive code, even slowly, get on the air and start making QSOs. Get involved in CW contesting, rag chewing, DX chasing, etc. Remember that you are learning Morse Code to be a Radio Operator, not just to pass a test.
11) If your HF rig doesn't have a sharp filter (400-500 Hz), get one and install it. Read the manual about how to use the rig on CW, often the default settings are optimized for SSB. Best operation usually requires turning off the AGC, turning the RF gain down and the AF gain up. The S-meter and AGC won't work under those conditions but that's no big loss; they’re not essentials.
12) Keep at it. There may be times when it seems as if you are making no progress, and times when you make rapid progress. What matters is that you keep practicing every day. Nobody was born knowing the skills you're trying to learn.
A bit of work? Sure it is, but well worth it, because all those steps make learning the code easier. And the work is trivial compared to what you can do with the skills once they're learned.
But a person has to be willing to do what's required. And they have to actually do those things.
