70cm repeater offset

The difference between the repeater’s receive frequency and its transmit frequency is called the offset. So, the offset is a frequency value in units of hertz, kilohertz, or megahertz.

The offset is the shift the radio will do when you transmit. VHF and UHF repeaters are listed in megahertz, and 600 kilohertz is 0.6 MHz, so you add or subtract 0.6 to the repeater frequency as needed to get the transmit frequency .14 May 2012
