How may amateurs use the 219 to 220 MHz segment of the 1.25 meter band?

• A. For general amateur radio operations
• B. Fixed digital message forwarding systems only
• C. Only for emergency communications
• D. Voice communication only

Answer: (B)

The use of the 219 to 220 MHz segment of the 1.25 meter band is specifically designated for certain types of communications. This segment is reserved primarily for fixed digital message forwarding systems. This means that the frequencies within this range can be utilized for automated digital communication processes that allow for the forwarding of messages, rather than for typical voice communications or general amateur radio operations.

The designation reflects the regulatory framework established by the FCC, which specifies this narrow range for digital applications, ensuring efficient use of the spectrum and promoting certain technological advancements in amateur radio. This specialized use helps in the development and operation of digital communication systems, aligning with the ongoing growth of digital technologies among amateur radio operators.
