• A. 146.520 MHz
• B. 144.200 MHz
• C. 147.420 MHz
• D. 145.500 MHz

Answer: (A)

The national calling frequency for FM simplex operations in the 2 meter band is 146.520 MHz. This frequency is designated for general use and serves as a standard calling frequency for two-way communication among amateur radio operators. It is recognized widely across the United States and is particularly used for informal conversations, emergency communications, and for establishing contact before moving to a different frequency for extended discussions. Operators typically monitor this frequency when they want to make initial contact with others in the area, making it an important and established part of VHF operating procedures. The choice of 146.520 MHz ensures that there is a common point where amateurs can call other stations, making it easier to find and communicate with each other. In contrast, the other frequencies listed are not designated specifically as the national calling frequency for FM simplex operations within the 2 meter band. Each of these frequencies has specific uses or is allocated to specific repeaters or other functions within the amateur radio community, which is why they are not the correct choice for a national calling frequency.
