Which frequency band is commonly used for local VHF communications?

• A. 30-50 MHz
• B. 144-148 MHz
• C. 420-450 MHz
• D. 900-928 MHz

Answer: (B)

The frequency band commonly used for local VHF (Very High Frequency) communications is 144-148 MHz. This range is part of the VHF spectrum allocated for amateur radio use, specifically designated for two-way voice communications, satellite operations, and various digital modes. This band is favored by amateur radio operators for local communications due to its ability to provide a good balance between range and ease of use. Signals in this frequency range can typically propagate well over varying distances, especially with the aid of repeaters, making it effective for both short-range and medium-range communication within local areas. The other frequency bands listed serve different purposes. The 30-50 MHz range is primarily used for HF communications, while the 420-450 MHz range falls under UHF (Ultra High Frequency), which is also used for various types of communications but not specifically for local VHF operations. The 900-928 MHz range is utilized for extra services and some digital applications, further differentiating it from local VHF communications.
