Q Signals

Ham radio operators have used Q signals to help clarify messages since the beginning of radio but we didn’t invent them.

Q signals started back in 1909 with commercial radiotelegraph communications who called the Q signals the brevity code.

Hams adopted the Q signals as a way of asking questions or making statements in simple three-letter code that was much easier to transmit using primitive equipment.

The Q signals are still used today to aid in the transmission of information and speed up communications. CW traffic nets use special Q signals.

The ability to use Q signals is the sign of a top-notch operator.
