How It Works
System Fusion uses a digital mode called C4FM in a 12.5 kHz channel. Fusion radios also do ordinary FM, so one radio covers both.
Many Fusion repeaters run in automatic mode: they pass digital when a digital station talks and FM when an FM station talks. That’s why a Fusion repeater doesn’t shut out hams with older radios.
Radios offer a few digital settings. DN is the normal digital voice mode; VW trades error correction for fuller audio; AMS (automatic mode select) lets the radio follow whatever the other station is using.
WIRES-X
WIRES-X is Yaesu’s internet linking. A node is a Fusion radio connected to the internet through Yaesu’s interface; it may be a repeater or someone’s home station. Nodes connect to rooms, which are like talkgroups: a room may be a national gathering place, a regional net or a club.
From your radio you can search for rooms and connect to one, if your local node allows it. The radio’s display shows which room you’re in.
Other Fusion Networks
Fusion repeaters and hotspots can also connect to open networks run by hams, called YSF reflectors and FCS. They work the same way from the radio’s side. Your local repeater owner will know which the repeater uses.
