The International Telecommunications Union [ITU] is the international organization coordinating global radio usage. The Amateur Radio organizational unit of the ITU is the International Amateur Radio Union [IARU]. The use of a common alphabet and pronunciation for communication is highly recommended by these organizations. Consistent worldwide usage improves the ability to communicate quickly and accurately. The following table lists the current recommended values. The use of "other" representations should be discouraged.
The bold face syllables in the Pronunciation area are to be emphasized.
English speakers should note the lack of an "R-sound" in the letters "O" and "V" phonetic representations.
Q-signals are a set of abbreviations used to save time during communications. They even allow communication between operators who don’t speak a common language. While Q-signals were originally developed for use by Morse operators (CW), modern hams use them with mostly all modes (phone, RTTY, etc.). You will often hear, "QRZ?" which translates to "Is someone calling me?" or "I’m getting a little QRM." which is "I’m receiving some interference."; or perhaps "Let’s QSY up 2" as operators change from a frequency to a slightly higher frequency (up 2 kHz). Q-signals are a radio shorthand method older than the start of wireless (radio) communication they were initially developed for use with the even older telegraphy codes (telegraph wires). The table below lists the more common Q-signals currently used by hams.
