Sub-tones

The Tone column shows the sub tone assigned for each frequency. There 

are 50 QT (CTCSS quiet tones) and 210 DQT (digital quiet tones that can 

be selected. These tones are used to privatize conversations and reduce in-

terference from other users on the same frequency. A CTCSS/QT/DQT tone 

is a sub-audible 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 different from the one set up in your transceiver, you will not hear 

the signal but only the LED will show frequency activity. Likewise, signals 

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

matches the tone set up in your transceiver.
There are 38 CTCSS standard tones (1-38) plus 12 extra QT tones. The 

38 tones are common on other 446 & 464MHz radios such as the Zartek 

Pro8 or Pro5. If the tone is left “OFF”, the frequency is left “open” to receive 

communication from any tone, but your transmitter will not be decoded by a 

radio with a tone.
