Which Q signal indicates that you are changing frequency?

Q signals were originally developed for Morse code (CW) communication to save time when sending common messages, but they are also widely used in voice communications today. The Q signal "QSY" specifically means "change frequency." For example, an operator might say "Let's QSY to 146.520 MHz" to move the conversation to that frequency. Understanding the distractors is key for the exam. "QRU" means "I have nothing for you." "QSL" means "I acknowledge receipt" or confirms a contact. "QRZ" means "Who is calling me?" Memorizing these common Q signals will help you immensely both on the test and on the air.
