The Q-signal procedurals are for use in Morse communications, but some have crept into voice usage as well, with similar meanings.
QRL is never spoken but it is customary to say "Is this frequency in use?" before making a call on an apparently-free frequency.
QRM is sometimes spoken as "you're getting QRMd" or "there's a lot of QRM" to indicate that the frequency is very congested.
QRP has a more absolute "low power operation" meaning rather than a relative "please lower your power" one. "Operating QRP" refers to the sport of trying to make contacts with a low a power as possible, usually 5 watts or less.
QRT is sometimes used to indicate that one is signing off. "I'm gonna go QRT now."
QRZ is always spoken "Q R Zed" and is used when one catches part of a call, particularly on an FM repeater, but can't tell which station is being called. If I hear a friend of mine call someone, and it might be me, but I'm not sure, I might say "QRZ for KF9FF?" Can be used this way whenever there is doubt about whom the calling station is calling or what they want.
QSL when spoken either as a question or a statement has much of the meaning of "okay" or "I understand" or "I will comply." "I'll meet you later on at the house, QSL?" When communication quality is poor, "QSL" is sometimes repeated three or more times to indicate that the message was indeed received.
QSO when spoken simply means "2-way contact." "Eyeball QSO" refers to a face-to-face meeting.
QST is usually used to introduce a broadcast message to all amateurs (the only type of one-way message allowed on amateur radio). "The following is a QST:".
QSY when spoken is either a suggestion or an announcement that one is changing frequencies. "QSY simplex?" is a suggestion that the two conversing parties leave the repeater to another non-repeater frequency in order to free up the repeater resource. Signing off using "this is KF9FF, QSY" conveys that I cannot be reached on the current frequency any longer (lest anyone try).
QTH has the identical meaning as in Morse. "What's your QTH?" "I'm nearly home."
