Standard offsets are:

29 MHz 100 kHz (-) |
147 MHz 600 kHz (+) |
1.2 GHz 12 MHz (-) |

50 MHz 500 kHz (-) |
222 MHz 1.6 MHz (-) |
2.4 GHz 20 MHz (-) |

145 MHz 600 kHz (-) |
440 MHz 5.0 MHz (-) ** |

146 MHz 600 kHz (+ or -) |
900 MHz 25.0 MHz (-) |

** Plus Offset In Some areas - notably Northern California.
When a repeater receives below the transmit frequency it is termed a minus offset. A repeater that transmits on 147.13 MHz and receives on 147.73 has a plus offset. Repeater input frequencies are given as either + or - signs to indicate whether the user's transmit frequency is above or below the repeater transmit frequency. Repeaters that have outputs in the lower part of the 146 MHz portion are often plus offsets while those operating in the upper portion of 146 MHz are minus offsets. See your repeater guides. Most of the new rigs default to the accepted offsets.
