What is Yaesu System Fusion?
System Fusion is Yaesu’s implementation of Digital Amateur Radio, utilizing C4FM 4-level FSK Technology to transmit digital voice and data over the Amateur radio bands. In the early 2000’s GMSK emerged in the Amateur radio market as the dominant digital mode, however in 2013 Yaesu introduced “System Fusion” which quickly became the dominating digital format in Amateur radio because of quality, reliability and enhanced performance in a wide range of environments.
Digital Communication modes have gained popularity over the years in the market because of superior performance in environments with interference, noise and other contributing factors that degrade the quality of a standard FM Analog signal. Narrower bandwidth and the need for increased spectrum have led to the development of digital communications technology, which has been widely adopted in the Public safety and private business sectors that use two-way radio technology. Unlike it’s commercial counterpart, System Fusion is an Amateur Friendly Digital Operating mode, straying away from some of the design considerations that make commercial solutions less appealing and more difficult for Amateur Radio Operators, providing a simpler interface and features that meet the demands and needs of the Amateur enthusiast specifically. Below you will find more information on this marvelous new technology, and how it can meet every operators demand and needs for a clear and simple Digital Experience.
The Four Operating Modes of System Fusion
V/D (Digital Narrow) - Voice+Digital or “V/D” mode
Voice FR (VW) Mode - Utilizes all available bandwidth for high-fidelity voice operation, providing the most crystal clear of voice communications.
Transfer data such as images or text messages at full rate with speeds up to 9600 Bits-per-second
Analog FM Mode
Maintains backwards compatibility with existing Analog FM Equipment, allowing a wide range of users to experiment with System Fusion Digital.
Capabilities such as Automatic Mode Select (AMS) On the DR-1X Repeater allow an even wider range of users to communicate, by running the repeater in “Fixed FM” mode on Transmit, and “Automatic Mode Select” on receive the repeater will automatically detect the incoming signal and convert it to an Analog FM Transmission. This mode allows digital users to communicate with existing Analog FM users without the need to switch their radios into FM Mode, allowing crystal clear Digital reception into the repeater that is converted into a conventional FM Signal.
Automatic Mode Select - Complete Digital Co-existence
This function instantly recognizes whether the received signal is C4FM digital or conventional FM. The communication mode automatically switches to match the received mode. Even if a digital signal is being used, you can switch to FM communication if radio signals are received from a FM station. This function enables stress-free operation by removing the need to manually switch the communication method each time.
AMS function breaks down into the following operating modes that are fully selectable by the radio user:
AUTO: The both RX/ TX mode is automatically selected from one of the four operating modes (DN, VW, DW and FM) to match the characteristics of the received signal. This is the current AMS operation.
TX MANUAL: The both RX/ TX mode is automatically selected from four operating modes to match the characteristics of the received signal. And if desired to change the TX mode, by pressing the Microphone PTT switch momentarily, the TX mode switch between DN and FM modes.
TX FM FIXED: The RX mode is automatically selected from one of the four operating modes, but the TX mode is fixed to FM.
TX DN FIXED: The RX mode is automatically selected from one of the four operating modes, but the TX mode is fixed to the ‘DN’ (Digital Voice Narrow) mode.
TX VW FIXED: The RX mode is automatically selected from one of the four operating modes, but the TX mode is fixed to the ‘VW’ (Digital Voice Wide) mode.
WiRES-X - Wide-Coverage Internet Repeater Enhancement System
WIRES-X (Wide-Coverage Internet Repeater Enhancement System) is a comprehensive and easy-to-use system for linking repeaters and/or home stations together, using Internet voice technology. Now you can talk to old friends, or make new ones, around the world.
More information on WiRES-X Can be found by visiting the WiRES-X Information Page
WIRES (Wide-coverage Internet Repeater Enhancement System) is an Internet communication system which expands the range of amateur radio communication. For WIRES-X, an amateur node station connecting to the Internet is used as the access point and connects the wireless communication to the Internet. Users' stations can communicate with other amateur stations all over the world using a node within the radio wave range.
WIRES-X supports the C4FM digital and the clear and crisp voice technology enables high sound quality. By repeating C4FM digital data as it is via the Internet, users can enjoy clear voice communications even if they are thousands of miles away each other.
Utilizing the digital communication, the WIRES-X operation is simple, easy and user friendly.
Varieties of the new functions as well as voice communications expands opportunities for enjoyment of ham station operation.
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.
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.
Node owners can freely create a room ID using letters and numbers. The ID works a bit like the name of a person. Easy to understand, meaningful names, unique names, memorable names... all are possible and can be used in a targeted search. A history of previous nodes and rooms, and a memory function with five categories makes it a snap to find and connect with a particular ID.
The WIRES-X node consists of a PC, the WIRES-X connection kit HRI-200 and a transceiver and is a repeater station used as the WIRES-X access point to connect the Internet and the wireless signal alternatively.
The WIRES-X node can open and run a community space "room" where multiple nodes can connect at the same time. Furthermore, the news functions allows you to upload/download messages or images to/from each node or room.
