Wide-coverage Internet Repeater Enhancement System

Lore & Background

WIRES began as an experimental Internet linking project in the United States (California). Initial Beta testing led to the development of an expanded and enhanced protocol with WIRES II. Yaesu later terminated WIRES-II service on Saturday, September 30, 2017 at 06:00 UTC, suggesting users instead use the WIRES-X Internet linking system. WIRES-X supports the C4FM digital and voice technology, enabling high sound quality by repeating C4FM digital data as it is via the Internet.

Reader's Guide

WIRES is notable as a de facto standard created by Yaesu for linking amateur radio repeaters over VoIP, using DTMF signaling without proprietary tones, thus allowing any manufacturer's radio with a DTMF keypad to initiate the Internet link. Its development began as an experimental project in California, leading to the enhanced WIRES II protocol, which was later terminated in 2017. The successor, WIRES-X, supports C4FM digital and voice technology, preserving sound quality by repeating digital data directly over the Internet. The system's legacy lies in its open signaling approach and its evolution from an experimental project to a widely used linking method, though the termination of WIRES II marked a shift toward digital-focused WIRES-X. The article lists related systems such as EchoLink, eQSO, the Internet Radio Linking Project, and Free Radio Network variants, indicating WIRES' place within a broader ecosystem of amateur radio VoIP linking solutions.

Did You Know?

• WIRES uses DTMF signaling to make Internet connections from a repeater or home station.
• No proprietary tones or connection formats are used, so any manufacturer's radio with a DTMF keypad can bring up the link.
• WIRES-II service was terminated on Saturday, September 30, 2017 at 06:00 UTC.
