Radio Settings
To use a repeater you need to listen to its transmitter frequency and transmit on its receive frequency. This can be confusing so these are the settings you need for your radio.
Transmit on 145.175MHz, receive on 145.775MHz and select a CTCSS tone of 82.5Hz. It is advisable to use tone squelch set to 82.5Hz on your radio. Tone squelch will only open when your radio hears the CTCSS sent with the FM signal. Without tone squelch you will hear the digital noise when the repeater is in digital mode.
On many radios, you select the receive frequency of 145.775MHz and an offset of minus 0.6MHz with a tone of 82.5Hz. We recommend you select tone squelch if your radio has this function. This will only open your radios squelch when it detects the repeaters 82.5Hz tone and you will not hear the digital noise if the repeater is being used in a digital mode.
