Question T1B04
From subelement T1 - T1B
Which amateur band includes 146.52 MHz?
Why is this correct?
146.52 MHz falls within the 2-meter amateur band (144-148 MHz). Amateur bands are named by their approximate wavelength, not frequency. The 6-meter band covers 50-54 MHz, the 70-centimeter band covers 420-450 MHz, and 20 meters is an HF band at much lower frequencies. Since 146.52 MHz sits squarely in the 144-148 MHz range, it belongs to the 2-meter band.
Memory tip
Remember that higher frequencies correspond to shorter wavelengths. As frequency increases from HF through VHF to UHF, the band names progress from larger wavelengths (meters) to smaller ones (centimeters). This inverse relationship helps you quickly eliminate obviously wrong choices.

The frequency 146.52 MHz is actually the national simplex calling frequency for 2-meter operation. In practical amateur radio, this frequency serves as a common meeting point where operators can establish contact before moving to another frequency. Understanding band limits isn't just for the test—knowing your frequency privileges ensures you operate within your license class authorization and avoid interference with other services.
Think about it
Why do you think amateur radio bands are named by wavelength rather than frequency, and how does this naming convention help operators choose appropriate antennas?
