Question
What is a common repeater frequency offset in the 70 cm band?
Answer Options
- A) Plus or minus 5 MHz
- B) Plus or minus 600 kHz
- C) Plus or minus 500 kHz
- D) Plus or minus 1 MHz
Correct Answer: A
Explanation
Similar to the 2-meter band (T2A01), the 70-centimeter band (420 MHz to 450 MHz) uses a standard frequency offset for repeater operation. Because the frequencies are higher (UHF), the necessary physical separation between the transmit and receive frequencies is much wider.
The common offset is \pm 5 MHz (megahertz). This means if a repeater transmits on 445.000 MHz, your radio must transmit on either 450.000 MHz (plus offset) or 440.000 MHz (minus offset). Using these standardized offsets is crucial for easily programming your radio to access local repeaters.
