Repeater Operation
Repeater stations, usually located on mountaintops or other high locations, provide a
dramatic extension of the communication range for low-powered hand-held or mobile
transceivers. The VX-120/170 includes a number of features which make repeater operation
simple and enjoyable.
Repeater Shifts
The VX-120/170 has been configured, at the factory, for the repeater shift set to 600 kHz.
Depending on the part of the band in which you are operating, the repeater shift may be
either downward (–) or upward (+), and one of these icons will appear at the top of the LCD
when repeater shifts have been enabled.
Automatic Repeater Shift (ARS)
The VX-120/170 provides a convenient Automatic Repeater Shift feature, which causes the
appropriate repeater shift to be applied automatically whenever you tune into the designated
repeater sub-bands in your country. These sub-bands are shown below.
If the ARS feature does not appear to be working, you may have accidentally disabled it.
To re-enable ARS:
1. Press the [F/W] key, then press the [0(SET)] key to enter the Set mode.
2. Rotate the DIAL knob to select Set Mode Item 4: ARS.
3. Press the [F/W] key momentarily to enable adjustment of this Item.
4. Rotate the DIAL knob to select “ARS. ON.”
5. When you have made your selection, press the PTT switch to save the new setting and
return to normal operation.
Manual Repeater Shift Activation
If the ARS feature has been disabled, or if you need to set a repeater shift direction other than
that established by the ARS, you may set the direction of the repeater shift manually.
To do this:
1. Press the [F/W] key, then press the [(4)RPT] key to enable selection of the repeater shift
direction.
2. This provides a “short-cut” to Set Mode Item 35: RPT.MOD.
3. Rotate the DIAL knob to select the desired shift among “RPT.–,” “RPT.+,” and
“RPT.OFF.”
