12QUIET TALK (QT)/ DIGITAL QUIET TALK (DQT)Your dealer may have programmed QT or DQT signaling on your transceiverchannels. A QT tone/ DQT code is a sub-audible tone/code which allows you toignore (not hear) calls from other parties who are using the same channel.When a channel is set up with a QT tone or DQT code, squelch will open onlywhen a call containing a matching tone or code is received. Likewise, signals thatyou transmit will be heard only by parties whose QT/ DQT signaling matches yourtransceiver.If a call containing a different tone or code is made on the same channel you areusing, squelch will not open and you will not hear the call.
