| If a repeater has an uplink tone, you must enter it to access the repeater. But, if you don't program a downlink tone (often called a decode tone) into your radio, you can still hear the repeater uninhibited. In fact, many repeaters do not transmit a downlink tone. So why bother to program one in if you can hear the repeater without it? | If a repeater has an uplink tone, you must enter it to access the repeater.

| Refer to the RepeaterBook database to see if the repeater is transmitting a downlink tone. If you set your radio to encode and decode tones when no downlink tone is being transmitted, you will not hear audio from the repeater at all. | Refer to the RepeaterBook database to see if the repeater is transmitting a downlink tone.
