Which of the bands available to Technician Class operators have mode-restricted sub-bands?

• A. A. The 6 meter, 2 meter, and 70 cm bands
• B. B. The 2 meter and 13 cm bands
• C. C. The 6 meter, 2 meter, and 1.25 meter bands
• D. D. The 2 meter and 70 cm bands

Answer: (C)

The 6 meter, 2 meter, and 1.25 meter bands indeed have mode-restricted sub-bands, which are segments of the band designated for specific types of communications. For example, in the 2 meter band, certain frequency ranges are allocated strictly for voice, while others might be reserved for digital modes or other types of communication. The same principle applies to the 6 meter band, where you typically find segments allocated for specific operating modes, such as FM, SSB (Single Side Band), and CW (Continuous Wave). The 1.25 meter band, which operates between 222 MHz and 225 MHz, is less commonly used but also has designated segments for specific modes. These restrictions help organize the use of the bands and minimize interference among operators using different types of equipment or communication methods. In contrast, some other bands may not have such clearly defined mode-restricted sub-bands, allowing for a wider array of communication modes without specific designations.
