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

The 219 to 220 MHz segment of the 1.25 meter band is specifically designated for fixed digital message forwarding systems. This means that amateur radio operators can utilize this frequency range for the transmission of digital data, often in a fixed or stationary manner, allowing for the reliable forwarding of messages in various applications.

This segment is set aside to accommodate the growing demand for digital communications within the amateur radio community, enabling operators to handle messages efficiently. The use of digital modes is advantageous as it often allows for more effective use of bandwidth compared to traditional voice communications.

While other modes like spread spectrum and fast-scan television may be part of amateur operations, the specific allocation of the 219-220 MHz range is primarily for digital message forwarding, which supports a range of messaging applications, including emergency communications when necessary.
