Quiet Talk (QT) and Digital Quiet Talk (DQT)

Some channels may have preset QT/DQT tones. A QT/DQT tone is

a subaudible tone which allows you to ignore (not hear) calls from

other parties who are using the same channel.

When you receive a signal that has a tone dierent from the one set

up in you transceiver, you will not hear the signal. Likewise, signals

that you transmit will only be heard by parties whose QT/DQT tone

matches the tone set up in your transceiver.

NOTE: Although using channels set up with QT/DQT tones relieves

you from listening to unwanted calls, it does not mean your

calls will be private.
