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

Plus or minus 5 MHz.

  1. Plus or minus 600 kHz
  2. Plus or minus 5 MHz ✔
  3. Plus or minus 500 kHz

Why: 70-centimeter repeaters (around 440 MHz) commonly use a 5 MHz split. The 600 kHz offset is the 2-meter standard.

Huh, didn't know that: The US 70-centimeter band runs from 420 to 450 MHz.

The dad joke
The 70 cm repeater has a 5 MHz offset. It likes its personal space.
