WIRES-X Remote Linking Report

Several local amateur radio operators in Otero County have set up System Fusion simplex nodes utilizing the HRI-200 WIRES-X interface from Yaesu.

Yaesu HRI-200 WIRES-X Interface

The HRI-200, when coupled to a compatible radio and a broadband Internet connection, provides a way for System Fusion users to connect to “nodes” and “rooms” outside the local area. Nodes and rooms are terminology used by Yaesu to denote individual and group endpoints to which users may connect using the WIRES-X system. For those familiar with Echolink terminology, WIRES-X “nodes” are similar in function to Echolink “-L” nodes and WIRES-X “rooms” are similar to Echolink Conferences, where many users may connect at once.

Thanks to implementation by Rick, N7SGT, and Justin, K5WAZ, I have been able to test various advanced features of System Fusion by accessing their HRI-200 enabled Fusion nodes from the FTM-400 radio mounted in my mobile station. The user interface of the FTM-400 makes System Fusion advanced linking a very simple and easy to implement endeavor.

Experiments I’ve conducted on air have involved remotely connecting a simplex node to rooms in Arizona, Texas, and even Moscow, Russia. In all three cases, digital audio passed over the connection seamlessly, and stations in Moscow were every bit as clear as local stations I’ve worked using C4FM. In addition to digital audio, Yaesu WIRES-X control software (which runs on a Windows computer connected to the HRI-200 interface) implements a type of digital “message board” which works similarly to an early 1990’s packet BBS system, but allows the upload/download of not only text messages, but also short digital audio messages, and even digital images to nodes and/or rooms in the system. All three types of messages are easily retrieved or uploaded using the FTM-400 WIRES-X interface.

Of the three major amateur radio digital systems I’ve used, System Fusion is by far the most user-friendly system of the three. D-STAR gateway configuration can prove a steep learning curve for new users, and that’s assuming the new user is able to successfully navigate the “registration” process to get entered into the official “Trust Server” in the first place. DMR “talkgroup” and “color” configuration is a language unto itself and presents a steep learning curve for DMR adopters. In contrast, System Fusion users will likely find using advanced features of SF systems fairly intuitive and straightforward. Backward compatibility with analog FM is also another unique feature of System Fusion hardware which may help smooth the “digital transition” for SF adopters.

Rick, N7SGT, has made his simplex node in Alamogordo available to all amateur operators. The node operates on a frequency of 146.460MHz, is operational daily from approximately 0700-2300 local time, and covers much of the Alamogordo metropolitan area. Please be courteous and drop any initiated links when concluding access of the node.
