Once again there is an advantage to using Morse code for communications. When we use our voice, especially on the radio, we tend to either speak too rapidly or to slur the words. Radio call signs are particularly prone to being misunderstood. By their very nature, with letters and numbers, the sounds run together. “G” sounds like, “E” or “D” and “B” or “C” if they are spoken rapidly. Also, interference on the airways can cause difficulty with clear vocal comprehension. Static from storms or other noise is able to make voice practically unreadable. Usually the Morse code signal can break through all of this and be copied correctly.
Over the years of developing radio communications several phonetic alphabets have been used. This means that words are used to represent letters. Sometimes each division of the military uses its own alphabet and some countries have their own, naturally using their language. A generally universal alphabet had evolved and is in wide use today. When you spell out a word using phonetics you are assured that you are copied correctly. Again, the ARRL operation manual lists this phonetic alphabet or it can be found online.
My call sign would be Kilo 8 Alpha Sierra Alpha and my name would be, Juliet Alpha Charlie Kilo. If you plan to work single side band or voice in your amateur radio hobby, you should learn this alphabet. It is always nice to be understood.

About Me
- Jack Stahl
- One of the wonderful aspects of using Morse code as a communications mode is that it is very indifferent as to the operator’s age. A good fist (one who sends well) can be ten years old or one hundred. I say this is wonderful because I am happily enjoying my sixty ninth year. I am new to the hobby of amateur radio, however, since I passed my technician test in September of 2006 and was awarded the license and call sign of KD8EJY by the FCC. I then passed my General exam in November and was granted my vanity call sign request of K8ASA by the FCC Although I am new to the amateur radio hobby, I am not new to Morse code. The ASA in my call sign refers to the Army Security Agency who sent me to a special school in 1956 to become efficient in Morse code. I was sent to Ethiopia for two years to give the army the benefit of my new skill. While back in those days my knowledge of Morse code was beneficial to our national security, 51 years later it now brings me pure pleasure. There has been a hiatus of fifty years between my army discharge and my becoming a ham and I do truly regret the fact that I missed out on all those years of enjoyment with the amateur radio hobby.
