System Fusion (C4FM) is Yaesu’s digital voice mode for amateur radio, offering clear digital audio alongside conventional analog FM on the same repeater.
Information about System Fusion / C4FM capability in the HOTARC area will be posted here as it becomes available. If you’re aware of a Fusion system or would like to help stand one up, please contact us or bring it up on the club net.
Meanwhile, see our Local Repeaters and the full Area Repeaters listing — the area table notes each system’s mode, including any digital (D-Star or C4FM) repeaters currently on the air.
