| To reduce confusion as to which frequency is being referenced in terms of a paired frequency set (duplex with separate input and output frequencies, as repeaters, typically use, the uplink frequency refers to the frequency that the repeater is receiving on. This is the frequency that is programmed into the user radio (HT, mobile, base) that you transmit to the repeater. This is the radio's transmit frequency. Some radios are equipped with automatic repeater offset/shift so the user does not actually program in a transmit frequency but simply indicates if the repeater has a positive (+) or negative (-) shift. | To reduce confusion regarding paired frequency sets (duplex systems with separate input and output frequencies, as typically used by repeaters), the **uplink frequency** refers to the **frequency that the repeater receives on**. This is the frequency programmed into the user radio (HT, mobile, or base) as the **transmit frequency**—the frequency you use to send signals to the repeater. |

| | Some radios are equipped with automatic repeater offset/shift functionality, meaning the user does not manually program a specific transmit frequency. Instead, the user selects whether the repeater uses a **positive (+)** or **negative (-)** shift, and the radio automatically calculates the uplink frequency. |
