Introduction
What is WIRES-X?
WIRES (Wide-coverage Internet Repeater Enhancement System) is an Internet communication system which expands
the range of amateur radio communication. WIRES-X uses local nodes (stations connected to the Internet via PCs)
as access points to relay communications of conventional amateur radio stations. Mobile stations using WIRES-X can
communicate with amateur stations all over the world by using a local node access station operating within an amateur
band. WIRES-X supports the new C4FM digital communications mode, enabling C4FM digital signals to be repeated
without deterioration of the communication quality. In addition, several new functions making use of digital formats are
also made available.
What is WIRES-X Portable Digital Node Function?
Using the WIRES-X Portable Digital Node function, you can operate a WIRES-X digital node station by directly
connecting the FT2D C4FM digital transceiver with the PC. The HRI-200 Internet interface kit is not needed and no
fixed or dynamic global IP address is required).
There are two operating modes of the WIRES-X Portable Digital Node function:
Portable Digital Node Mode
capable of Internet communication with digital stations.
Portable HRI mode
capable of Internet communication with both digital station and analog stations.
Portable Digital Node Mode
（
Supports Internet communication only in C4FM Digital Mode
）
Requires a Yaesu C4FM Portable Digital Node capable transceiver (FT2D as of 12/2018 or firmware updated) an SCU-
19 USB Connection Cable (FT2D) and a PC with WIRES-X Software and Internet connection.
Two forms of WIRES-X Access are supported, “
Access Point
” and “
Direct Operation
”.
In “
Access Point
” the Portable Node station (FT2D) can be used to communicate “On Air and relay nearby local C4FM
digital transceivers, while simultaneously connected with the Internet WIRES-X digital rooms and digital node stations.
In “
Direct Operation
”, the Portable Node (FT2D) station transceiver is used only for WIRES-X internet communications
without transmitting or receiving local “On Air” radio signals.
Access Point
In this mode, WIRES-X C4FM communications are made by either directly using the USB connected FT2D Node
Station PTT, microphone, and speaker, or via another local C4FM transceiver communicating on frequency with the
USB connected FT2D Node Station. The FT2D Node Station connects directly to the PC and internet, and commu-
nicates with WIRES-X Nodes and Rooms. The FT2D Node Station relays the local C4FM stations and signals to
the internet and transmits the internet Node and Room signals to the local stations. This mode allows the flexibility
to operate the Portable Digital Node directly with a single USB connected FT2D transceiver, or to access WIRES-X
Nodes and Rooms from one or several local C4FM transceivers.
