Scanning for CTCSS and DCS Tones/Codes
|
* Not all repeaters requiring a CTCSS tone or DCS code for access will
transmit one back. In that case, you would need to listen on the repeater's
input frequency for a station accessing the repeater and identify the tone they are using.
** Due to firmware changes in the UV5R/UV82 over time, this
procedure 'should' work fine. In no way can it damage the radio.
This procedure works in both VFO (frequency) and MR (channel) mode.
The Channel / Frequency being scanned must have R-CTCS turned
ON and set to a CTCSS tone (any tone). If
R-CTCS is OFF, the scan function will not work.
- Enter the desired channel or frequency.
- Select Menu / 11
If R-CTCS is OFF, perform the following to turn the function ON.
- Menu / 11 / Menu / ^ / Menu / Exit
This will turn R-CTCS ON and will enter a starting point for the scan.
To Scan, perform the following:
- Menu / 11 / Menu / *SCN
When the Scan stops, press Menu to store the CTCSS data.
- You can start the scan function (*SCN) prior a signal being received. When a signal is detected, the scan will start automatically. When it finds the
active tone, it will stop. Press Menu to store it.
Note 1: This procedure is for identifying the
tone only, not storing it in a channel. The standard channel
update must be used to reprogram the channel.
Note 2: When using the VFO mode, remember to turn the DCS or CTCSS tone back to OFF. |

Scanning for a DCS tone |
For DCS codes, use the above procedure using Menu 10 (R-DCS) rather than Menu 11.
When using the VFO mode, remember to turn the DCS or CTCSS tone back to OFF.
My thanks to Jim, KC9HI for the above examples.
