Wires-X and C4FM working together.
While we are primarily focused on System Fusion, however, we encourage experimenting with other digital protocols such as Wires-X, Winlink, FT8, JS8Call, etc.
Wires-X control using radio
Currently active nodes and rooms can be searched in real time, and viewed on the display of your transceiver. The display list is sorted according to the number of stations currently connected to the room, in other words by popularity. This lets you quickly find other active stations to communicate with.
Smart Access Function
WIRES-X automatically connects to nodes and rooms via the Internet. No more need to verify connection IDs or transmit cumbersome DTMF connection codes.
Information about nodes and rooms is exchanged via C4FM Digital signaling. Thanks to automatic reconnection to the previous contact, all you need to do is press PTT and start talking.
Easily search for new nodes and rooms, and initiate communication promptly when you find an ID that captures your interest.
