3- Configuring the radio
There are a few important setting we must adjust on the radio in order to use the repeater:
- Downlink frequency
- Offset
- Uplink tone
These instructions are for the Yaesu FT-65R radio but they are similar to how most mobile radios would work.
The main source for this page is the Yaesu FT-65R operating manual1. It is the source for all instructions about the Yaesu FT-65R radio on this page, unless marked otherwise.
Downlink frequency
The downlink frequency is the frequency at which the radio receives.
- Switch to VFO mode. Press
*V/Mto toggle VFO mode - Select the band. Select the right frequency band (in our case, 144Mhz) by pressing the
#BANDkey until the right value is displayed. - Select the frequency. Use the
⯅and⯆keys or the numpad to select the downlink frequency for the repeater. In our case, 147.12Mhz
At this point, this is usually all one would do to establish contact. When using a repeater, however, it becomes a bit more complicated.
Offset/Shift
This is how you indirectly tell the radio the uplink frequency (the frequency at which the radio must transmit)
Some radios, including the Yaesu FT-65R, contain an Automatic Repeater Shift feature or a similar feature. This feature automatically calculates and applies the offset for you. While this feature is generally correct and useful, in some cases it may be absent or incorrect. In our case, it could be used, but for some other repeaters it could not be. To cover these cases, we are disabling it in this guide.
If you use the ARS feature, make sure it is ON and skip this section.
-
Disable ARS (Automatic Repeater Shift).
- Enter Set Mode by holding
F - Select the item "24 REPEATER" by using the
⯅and⯆keys - Press
Fto select ARS - Switch to OFF with the
⯅and⯆keys - Press
Fto select
- Enter Set Mode by holding
-
Configure the offset manually.
- Select the item "MODE" by using the
⯅and⯆keys - Press
Fto select - Select the item "+REP" (if the offset is positive) or "-REP" (if the offset is negative) by using the
⯅and⯆keys - Press
Fto select - Select the item "SHIFT" by using the
⯅and⯆keys - Press
Fto select - Select the desired offset (in our case, 0.600MHz) by using the
⯅and⯆keys - Save and exit by pressing the transmit button (
PTT)
- Select the item "MODE" by using the
Uplink tone
The options for this feature are described in the Yaesu FT-65R advanced manual and that is the source for that section2.
- Enter Set Mode by holding
F - Select the item "8 CTCSS" by using the
⯅and⯆keys - Press
Fto select - Set the transmit tone, if any
- Select the item "TX" (for transmit) by using the
⯅and⯆keys - Press
Fto select - Select the desired transmit tone (in our case, 103.5MHz) by using the
⯅and⯆keys - Press
Fto select
- Select the item "TX" (for transmit) by using the
- Set the receive tone, if any
- Select the item "RX" (for receive) by using the
⯅and⯆keys - Press
Fto select - Select the desired receive tone (in our case, like most cases, there is none so we can leave it as is) by using the
⯅and⯆keys - Press
Fto select
- Select the item "RX" (for receive) by using the
- Set the squelch type. This tells the radio if and how to use those tones
- Hold
Fto go back to Set Mode - Select the item "29 SQL TYPE" by using the
⯅and⯆keys - Select the desired mode depending on if the repeater uses transmit tone (T-TONE), receive tone (R-TONE), both (TSQL) or neither (OFF) by using the
⯅and⯆keys - Save and exit by pressing the transmit (
PTT) button
- Hold
Other considerations
Power
As always, make sure the transmission power of the radio is both sufficient and not too high to properly reach the target (in this case, the repeater). It is preferred to use the least power that gets you in range3. In my case, 2.5W is sufficient. Refer to your radio's operating manual for how to adjust power if necessary.
Audio volume
Adjust the audio volume of the radio to be sure to hear the other side when they talk. Forgetting to do this is a good way to wonder why your radio isn't working. On the Yaesu FR-65R, use the PWR/VOL knob to adjust volume.1
