What is a common repeater frequency offset in the 2 meter band?

A common repeater frequency offset in the 2 meter band is plus or minus 600 kHz. This standard offset is established to establish a separation between the input and output frequencies of a repeater, allowing for effective operation without interference. The 2 meter band is particularly popular among amateur radio operators, and the 600 kHz offset helps ensure that nearby repeater operations do not interfere with one another, maintaining clear communication channels.

The other frequency offsets listed do not align with the established norms for the 2 meter band repeaters. For example, a 5 MHz offset is more typical of higher frequency bands, while 1 MHz or 500 kHz are not standard for the 2 meter band usage. Understanding these offset frequencies is essential for effective amateur radio communication and for proper use of repeaters, making the knowledge of the 600 kHz offset particularly valuable for operators.
