What is the operating range of the VHF Transceiver?

• A. 108.000 - 136.975 MHz
• B. 118.000 - 136.975 MHz
• C. 118.000 - 137.000 MHz
• D. 120.000 - 136.975 MHz

Answer: (B)

The range being tested is the aviation VHF airband used for voice communications between aircraft and ground stations. In aviation, the VHF airband runs from 118.000 MHz up to and including 136.975 MHz. That’s why this is the correct choice: it matches the standard allocation for air-to-ground radio, ensuring you’re operating within the allowed frequencies.

Other ranges either include frequencies outside the airband (for example, the navigation band sits below 118 MHz) or extend beyond the official upper limit (136.975 MHz), or start too high and miss the lower part of the airband. The upper boundary of 136.975 MHz is specific, so 137.000 MHz isn’t part of the allocated airband.
