System Fusion on Android, one tap from a reflector.
Pick a YSF reflector from the list and talk. The reflector is the destination, so there is no second step, no hotspot and no address to type.
What System Fusion is
System Fusion is a digital voice mode for amateur radio that uses C4FM modulation. Stations identify by callsign. Over the internet, System Fusion stations meet on YSF reflectors: servers that link everyone connected to them.
In Unified Radios, System Fusion runs over the internet, straight from the app, on any Android phone or tablet and on supported radios. The app connects with the callsign on your account, and like every digital mode in the app, System Fusion uses your DMR ID too.

One list holds the YSF reflectors. It is refreshed daily, with each reflector checked for a reply.

System Fusion questions.
Do I need a System Fusion radio or a hotspot?
The app connects to YSF reflectors itself, over Wi-Fi or cellular, from an Android phone, tablet or supported radio.
What is a YSF reflector?
A server on the internet that links System Fusion stations. Everyone connected to the same reflector hears each other, and in the app the reflector you pick is the destination.
How do I find a reflector?
Search the list in the app by name or place. It is refreshed daily.
Is System Fusion free in the app?
Yes. Talking on YSF reflectors and the reflector list come with every free account.
What does the app need from my account?
Sign up with your callsign and we bring in your DMR ID, which every digital mode uses. You can also start without a callsign and add both later.
