Which amateur band includes 146.52 MHz?

The answer is 2 meters because the 2-meter band, which ranges from 144 to 148 MHz, includes the frequency 146.52 MHz. This band is commonly used for local communications, including voice and data, and is popular among amateur radio operators for its favorable propagation characteristics and ease of access.

The other bands mentioned do not encompass this specific frequency. The 6-meter band operates between 50 and 54 MHz, while the 20-meter band covers frequencies from 14.0 to 14.35 MHz. The 70-centimeter band operates from 420 to 450 MHz. Each of these bands has its distinct frequency range and uses, but none include 146.52 MHz, confirming that the 2-meter band is the correct choice.
