VX-3R Operating Manual
1. Press and hold in the [TXPO] key for one second to enter the Set mode.
2. Rotate the DIAL knob to select Set Mode Item 25: DCS RV.
Note: Do not forget to pull the DIAL knob to rotate the DIAL knob.
3. Press the [TXPO] key momentarily to enable adjustment of this Set Mode Item.
4. Rotate the DIAL knob to select one of the following modes:
R-N.T-N: Receive and transmit the Normal DCS Tone.
R-I.T-N: Receive the Inverted DCS Tone and transmit the Normal DCS Tone.
R-B.T-N: Receive the both Normal and Inverted DCS Tones and transmit the Normal DCS Tone.
R-N.T.I: Receive the Normal DCS Tone and transmit the Inverted DCS Tone.
R-I.T-I:
Receive and transmit the Inverted DCS Tone.
R-B.T-I: Receive the both Normal and Inverted DCS Tones and transmit the Inverted DCS Tone.
5. When you have made your selection, press the [TXPO] key momentarily, then press the PTT switch, to
save the new settings and exit to normal operation.
This is different than the usual method of restoring normal operation, and it applies only to the configuration
of the CTCSS/DCS frequencies. Remember to restore the default setting “R-N.T-N” (Receive and transmit
the Normal DCS Tone) to when done.
Tone Search Scanning
In operating situations where you don’t know the CTCSS or DCS tone being used by another station or
stations, you can command the radio to listen to the incoming signal and 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; you may have to listen to the station(s) transmitting on
the repeater uplink (input) frequency in order to allow Tone 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 previous discussions). In the
case of CTCSS, “T SQ” will appear on the display; in the case of DCS, “DCS” will appear on the
display.
2. Press and hold in the [TXPO] key for one second to enter the Set mode.
3. Rotate the DIAL knob to select Set Mode Item 86: TN FRQ when TONE SQL is selected, or Set Mode
Item 24: DCS CD during DCS operation.
Note: Do not forget to pull the DIAL knob to rotate the DIAL knob.
4. Press the [TXPO] key momentarily to enable adjustment of the selected Set Mode Item.
5. Press and hold in the [BAND] key for one second, appear “T SRCH” (for CTCSS Tone Search) or “D
SRCH” (for DCS Tone Search) on the display, then release the [BAND] key to start scanning for the
