Tone Search ScanningIn operating situations where you don’t know the CTCSS tone or DCS code being usedby another station or stations, you can command the radio to listen to the incoming signaland scan in search of the tone being used. Two things must be remembered in this regard: You must be sure that your repeater uses the same tone type (CTCSS vs. DCS). Some repeaters do not pass the CTCSS tone or DCS code; you may have to listento the station(s) transmitting on the repeater uplink (input) frequency in order to allowTone Search Scanning to work.To scan for the tone in use:1. Set the radio up for either CTCSS or DCS Decoder operation (see the previousdiscussion). In the case of CTCSS, “TSQ” will appear on the display; in the case ofDCS, “DCS” will appear on the display.2. Press the Microphone’s [P3] key momentarily to startscanning for the incoming CTCSS or DCS tone/code.3. When the radio detects the correct tone or code, it willhalt on that tone/code, and audio will be allowed topass.4. Press the Microphone’s [P3] key momentarily to lock inthat tone/code and exit to normal operation.If the Tone Scan feature does not detect a tone or code, it will continue toscan indefinitely. When this happens, it may be that the other station is notsending any tone. You can press the Microphone’s [P3] key to halt the scan at anytime.You may listen to the (muted) signals from the other stations during Tone Scanning whenSet Mode Item “54 TS MUT” is set to “OFF”. See page 71 for details. You can alsochange the Tone Search scanning speed, using Set Mode Item “55 TS SPD”. See page71 for details.Tone Scanning works either in the VFO or Memory mode.24CTCSS/DCS/EPCS OperationFT-2980R Operating Manual
