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

Repeaters use two different frequencies: one for receiving and one for transmitting. The difference between these two frequencies is called the offset. In the 2 meter band (144-148 MHz), the standard offset is plus or minus 600 kHz (0.6 MHz). If the offset were too small, the repeater's powerful transmitter would overload its own receiver. The other options are standard offsets for different bands, such as plus or minus 5 MHz, which is the standard offset for the 70 centimeter band.
