Q-signals are a system of radio shorthand as old as wireless and developed from even older telegraphy codes. Q-signals are a set of abbreviations for common information that save time and allow communication between operators who don’t speak a common language. Modern ham radio uses them extensively. The table below lists the most common Q-signals used by hams. While Q-signals were developed for use by Morse operators, their use is common on phone, as well. You will often hear, “QRZed?” as someone asks “Who is calling me?” or “I’m getting a little QRM” from an operator receiving some interference or “Let’s QSY to 146.55” as two operators change from a repeater
frequency to a nearby simplex communications frequency.
