On which band is image transmission prohibited?

  1. 160 meters

  2. 30 meters

  3. 20 meters

  4. 12 meters

The correct answer is: 30 meters

The correct identification of the 30-meter band as the one where image transmission is prohibited stems from regulations set by the Federal Communications Commission (FCC) and international agreements regarding amateur radio operations. The 30-meter band is allocated for digital modes and CW (continuous wave) communication, emphasizing clear and efficient transmission of data without the complexities associated with image transmission. This prohibition is in place to ensure that the band is used for its intended purpose, maintaining its integrity for specific types of communications. The spectrum policy aims to minimize interference and enhance the quality of the communication experience for amateur radio operators utilizing digital modes. In contrast, other bands, such as 160 meters, 20 meters, and 12 meters, allow for a variety of transmission modes, including voice, image (such as slow-scan television), and other digital communications, reflecting a broader allocation for different communication techniques.
