They are composed of two Morse code alphabetic characters "run together"; that is, that omit the normal pause that would occur if they were being sent as two letters of text. They are normally represented in print by the two letters, often with a ligating bar above them. Abbreviations differ from prosigns in that they observe normal interletter spacing; that is, they are not "run together" the way prosigns are. Question: Which of the following is a possible reason that attempts to initiate contact with a digital station on a clear frequency are unsuccessful?

Forgot Password? Five words a minute was the requirement for the entry level Novice license and also for the renewable, but VHF only, Technician ticket. A General or Advanced class required 13 wpm and it was 20 wpm for an Extra. In the code requirement was eliminated for the Technician class, in it was reduced to 5wpm for all classes that still required code and in the code requirement was eliminated entirely. Whatever your reason for learning Morse code now, we have some links on this page that will help you. Enrollment is open to anyone with the desire to learn or improve their proficiency in Morse Code.
In ham radio, Morse code signals are often referred to as CW, which stands for continuous wave. Early radio signals died out quickly because they were generated by sparks. Soon, however, operators discovered how to make steady signals, or continuous waves, by turning the signals on and off with a telegraph key. Thus, Morse code and CW became synonymous. Set the rig to receive Morse code by selecting the CW mode and tuning to a frequency somewhere in the bottom 20 kHz to 30 kHz of an HF band. A wide filter allows you to find and tune in stations, whereas the narrower ones block out unwanted nearby signals. Tune until the pitch is comfortable to your ear. A low tone — Hz is most restful to the ear, but a higher tone — Hz often sounds crisper. Most radios are designed so that when you tune in a signal with a tone or pitch around Hz, the transmitted signal is heard by the other station at a similar pitch. When you tune in the signal at your preferred pitch, select a narrower filter if one is available to reduce noise and interference.
