What amateur band are you using if you are transmitting on 223.50 MHz?

Transmitting on 223.50 MHz places your signal in the 1.25 meter band, also known as the 220 MHz band. This band spans frequencies from 219 to 220 MHz, where 223.50 MHz falls within this range. The 1.25 meter band is allocated for amateur radio use in various regions, allowing operators to communicate and experiment using frequencies in this range.

The other options refer to bands that operate at different frequency ranges. The 15 meter band is centered around frequencies from approximately 21.0 to 21.45 MHz, and the 10 meter band covers roughly 28.0 to 29.7 MHz. The 2 meter band operates in the range from 144 to 148 MHz, which is noticeably higher than the frequency in question. Thus, identifying 223.50 MHz correctly as part of the 1.25 meter band is essential for understanding the various ham radio frequencies and their classifications.
