Connect to the repeater

F-troop is run on the Rolystonr repeater, VK6RAP, on 146.700 MHz FM - with an input frequency of 146.100 MHz.

If you've just got your radio, you might not know how to set it up so you can talk on-air using the repeater. This page is intended to help you get started. Of course it would be simple to tell you just to read the manual, but if you did, you probably wouldn't be reading this page would you?

Some background

A repeater is a radio that listens on one frequency, the input frequency, and broadcasts on another frequency, the output frequency. In the case of the Rolystone repeater, that's 146.100 MHz and 146.700 MHz respectively. You as a listener are listening to the repeater output, that is, the frequency on which it's transmitting, in our case, you tune your radio to 146.700 MHz FM.

If you want to say something, you need to tune to the repeater input, 146.100 MHz and transmit. The repeater will receive your signal - if you're in range - and transmit onto the output frequency.

If you wanted to, you could just keep swapping between those two frequencies, but you'd be running a good risk of getting the two mixed up, resulting in you and everyone else not hearing anything.

Below are the instructions for various radio's on how to configure operation for repeater use, that is, to make your radio magically switch to the correct frequency when you transmit.

Other Information

The Wireless Institute of Australia maintains a list of repeaters and their specific settings which you should consult before actually broadcasting into any repeater.

Excerpts from pages 56 and 57 from the user manual:
  1. Select 146.700 MHz as your frequency.
  2. Press the [MODE(<-)] or [MODE(->)] key so as to select the FM mode.
  3. Press the [FUNC] key momentarily, then rotate the SELECT knob, as needed, until Multi Function Row “d” [RPT, REV, VOX] appears on the display.
  4. Press the [A](RPT) key to activate repeater operation. One press of the [A](RPT) key will have set the transceiver for “Minus Shift” operation. In this situation, you will observe the “–” indicator on the display.
  5. Press and hold the [A](RPT) key for one second. This instantly recalls Menu Mode No-076 [RPT SHIFT].
  6. Rotate the DIAL know to select the desired shift frequency of 0.600 MHz. (The standard repeater offset around here is 600 KHz.)
  7. When done, press and hold in the [FUNC] key for one second to save the new setting and exit to normal operation.
  8. Close the PTT switch and speak into the microphone. You will observe that the transmitted frequency has shifted to 146.100 MHz. Release the PTT switch to return to the Receive mode and back to 146.700 MHz.
If you want to store this into a memory for easy recall, read up on the process on page 74. Note that you could also store this repeater as a split frequency as described on page 75.
