The use of data emission between 219 and 220 MHz is appropriate because this frequency range is designated for certain services that often involve data communications. In the context of amateur radio and the rules provided by the Federal Communications Commission (FCC), this allocation allows for various data modes, including packet radio and other forms of digital communication.

Voice emissions, though common in amateur radio, are typically associated with bands allocated specifically for voice communication, and while CW (continuous wave) is a popular mode, the specifics of this frequency range lean toward data protocols. Video transmissions are generally reserved for frequencies higher than what is allocated for this specific range. Therefore, recognizing that the 219 to 220 MHz range is primarily tailored for data transmission underlines why data is the correct choice in this context.
