So You Want to Learn Morse Code - Here Are Some Tips

By Gerald Wheeler

Like music, some people seem to have a natural talent to learn the Morse code effortlessly. During World War II it was common practice to gather a few hundred military recruits into a hall, introduce them to the World of "dahs and dits," and wash out the majority within two weeks. Those remaining "geniuses" became the wireless Aces of the War.
For most students, gaining control over the flow and rhythm of the sounds proved to be an arduous and fearsome task. Code practice machines used at this time consisted of paper rolls about an inch wide that ran past a light source. The rolls were perforated to create, from the electric eye, an almost perfectly sounded string of Morse code letters, numbers and messages. The student was systematically introduced to the character sound, as the instructor called out the letter's name. Soon another string of dots and dashes was added and another until a dizzying array of dahs and dits swam in the student's head. Since the practice sessions often lasted several hours or more, errors were practiced over and over and then when the paralyzing test was given, anxiety ran high with frustration and failure common.
Over the years, most students try to learn Morse code in just this same manner. It is no wonder that when the FCC decided to eliminate the code testing for amateur radio licenses that a great sigh of relief came from many long frustrated "would-be" hams.
However, another method appears to have gained many adherents. In the English speaking countries and in other language parts of the world, Morse code is being taught using a mnemonic system that mimics the sound of the code in the language of the learner. The dahs and dits can be heard as simple words and phrases instead. With this method and only forty characters to learn, a high percentage of students succeed at mastery.
It appears that the brain is capable of learning language quite readily when meaning is attached to sounds. Without meaning in the sounds themselves, the brain has no handles to make an attachment, causing the symbols to become hopelessly mixed. A mnemonic device is defined as: "any learning technique that aids memory. Commonly, mnemonics are verbal (such as a very short poem or a special word used to help a person remember something) but may be visual, kinesthetic or auditory. (Wikipedia.com) Mnemonics rely on associations between easy-to-remember constructs which can be related back to the data that is to be remembered. This is based on the principle that the typical human mind much more easily remembers spatial, personal, surprising, sexual, humorous or otherwise meaningful information than seemingly arbitrary sequences." The seemingly random string of dahs and dits of the letter take on meaning from the associated mnemonic. Thus the letter "D" might be more readily remembered as "Dog did it" instead of "Dah di di." Attach a picture of a hapless canine and "presto" the symbol is forever remembered.
Persons learning the Morse code this way find that they can master the code in a matter of days instead of months and that there really can be a lot of pleasure in acquiring and using this universal foreign language skill.

What If Our Communication Systems Fail? Morse Code Can Help

By Gerald Wheeler

Consider your average morning routine. Most of us begin taking in the day's news as soon as the clock radio wakes us up. Then there is the morning news brief from the television while eating breakfast followed by a local radio station during our commute. Throughout the day people continue to glean important events from news sites on the internet. Now consider what your day would look like if all of these resources fell silent.
There are continual reminders that our nation's power grid is much more fragile than we would like to admit. Such threats do exist not only as foreign or domestic, but extra-worldly as well. Modern power grids are managed by computer networks and the potential exists for hacking into those networks to interrupt the power supply. Another less sinister, but just as hazardous threat comes from outside our own planet. The very sun that we rely upon every day occasionally ejects powerful solar flares known as coronal mass ejections or CMEs. These powerful electromagnetic fields can wreak havoc on sensitive electronic components and have already caused major power outages in recent history and scientists continue to predict that the sun is primed for another such event.
The technology for electromagnetic bombs, developed over the past 30 years, is now available to download from on the internet! Googling it demonstrates the ease with which a would-be enemy could devastate society, creating an enormous blackout with mass panic and havoc. Such powerful electronic pulses pose a significant threat to breakdown all traditional communication including satellites that control every aspect of transportation, commerce and ultimately life.
Other potential problems with national and regional grids are not posed by external threats, but by the continued and rapid growth of our own cities. While such power demands are on the rise, the capacity to provide power to them is not keeping pace. The battle between environmental groups and political decision makers only seems to be maintaining the status quo and not improving the reliability of our energy needs.
If any one of these events transpire and our power grid fails, where would we get our news and information? While we could certainly continue to live day-to-day without a sizable amount of the information we take in, there is some information that we simply would find hard to live without. In the case of a regional or national disaster, reliable and accurate information can be the biggest factor in safety and survival.
How fortunate we are that there are trained amateur radio operators scattered across the country who are poised to fill this important gap if ever needed. With an emergency generator and communication tools, these operators have the equipment and coding skills necessary to process and relay important information at a moment's notice. Many of these operators utilize an assortment of methods, but among them Morse code gets through when other methods fail. As we have seen in so many movies, confirmed by actual real life experiences, the effectual transmission of dahs and dits between trained operators is a very useful method of communicating both securely and accurately.
If you prepare by learning Morse code, you will be on the front lines of the vital communication network and could be responsible for bringing peace, comfort and safety information to friends and family. Some things may be better left to others, but wouldn't you feel safer knowing that you have done everything you could do in an emergency? Morse code continues to be a valuable survival skill for you, your family and for the nation.

Backcountry Radio

I just found a quite good discourse on radio communications for outdoor gatherings, such as a meetup and campout. It touches on CB , FRS and VHF/UHF ham radio, but focuses primarily on GMRS, including portable repeaters.
It is from the Rainbow Gathering people, but regardless of what you may think of them, it is a worthwhile read. Click here to check it out.
