Notes

Q-signals are three letter combinations used to represent common phrases or sentences for CW operation. They may be used as a question with a question mark (?) or statement without the question mark.

Examples:

“QRZ?” is used to ask for the calling station(s) to identify again.

“Please (pse) QRS” is used as a request to send the code at a slower speed.

“The QTH is” is used to indicate this station’s location.

Although originally used for CW, many Q-signals have become acceptable for phone operation.
