Quiet Talk (QT) and Digital Quiet Talk (DQT) are functions that
reject signals from undesired parties that are using the same
channel as you. You will hear audio from the speaker only
when you receive a signal that contains a QT tone or a DQT
code that matches the one set up on the channel you are
using. If a call containing a different tone or code is made on
the same channel you are using, squelch will not open and
you will not hear the call. Likewise, when you transmit on a
channel set up with QT or DQT, the receiving station must
have a matching tone or code in order to hear your call.
Although it may seem like you have your own private channel
while using QT or DQT, other parties can still hear your calls if
they set up their transceiver with the same tone or code.
The default QT/ DQT settings for each channel is 67.0 Hz.
