6 ANALOG COMMUNICATIONS / 6.1 Using Signaling
Toggling the QT/DQT Decode Between Enabled and Disabled (Decode Signaling Enable/Disable)
Decode Signaling Enable/Disable is the function to enable or disable the QT/DQT decode.
If Decode Signaling Disable is enabled, the repeater cannot decode QT/DQT.
Note
The QT/DQT decode cannot be toggled between enabled and disabled when transmitting using the Repeat PTT control. The
・
QT/DQT decode can be toggled between enabled and disabled while transmitting using anything other than the repeat
behaviors.
・ When transmitting using the Repeat PTT control while Decode Signaling Disable is enabled, the QT/DQT (Primary)
configured for each channel is used for the signaling of the downlink signal from the repeater.
・
If the repeater waits to receive on a mixed channel, this function works only when an analog signal is received.
Toggling the QT/DQT Encode Between Enabled and Disabled (Encode Signaling Enable/Disable)
Encode Signaling Enable/Disable is the function to enable or disable the QT/DQT encode.
If Encode Signaling Disable is enabled, the repeater cannot encode QT/DQT.
Note
The QT/DQT encode can be toggled between enabled or disabled with Encode Signaling Disable or Encode Signaling
・
Enable during transmission but it cannot be toggled between enabled or disabled with Encode Signaling Enable/Disable.
・ When transmitting using the Repeat PTT control while Decode Signaling Disable is enabled, the QT/DQT (Primary)
configured for each channel is used for the signaling of the downlink signal from the repeater.
・
If the repeater transmits on a mixed channel, this function works only when an analog signal is transmitted.
Preventing the Receiving Party from Emitting the Squelch Tail Noise When Transmission Ends
(Squelch Tail Elimination)
Squelch Tail Elimination is the function to prevent the speaker of the receiving party from emitting the squelch tail
noise when transmission ends.
When transmission ends, QT Reverse Burst is output on a channel with QT configured in QT/DQT Encode, and DQT
Turn-off Code is output on a channel with DQT configured in QT/DQT Encode.
QT Reverse Burst
QT Reverse Burst is the function to transmit by changing the phase of QT at the end of the transmission. The duration
during which QT Reverse Burst is output is 160 ms. When the transceiver of another company is used, QT Reverse
Burst Phase is configured according to the QT decode function of the transceiver so that tail noise is not emitted.
Configuration using KPG-D7
