What is a common repeater frequency offset in the 70-centimeter band?

Repeaters operate by listening on one frequency and transmitting on another simultaneously. The difference between these two frequencies is known as the repeater offset or shift. For the 70-centimeter band (which spans from 420 to 450 MHz), the standard repeater offset is plus or minus 5 MHz. This wide separation helps prevent the repeater's own powerful transmitter from overloading and interfering with its sensitive receiver. A common distractor is 600 kHz, but that is the standard offset for the 2-meter band. You must associate the much larger 5 MHz offset specifically with the 70-centimeter band.
