A Multi-Destination DG-ID Gateway is a single front door to many different C4FM (Fusion) networks. It rounds out the XLX, URF, and fanout-bridge explainers — but it solves a different problem. Those projects connect different modes to each other. This one stays within a single mode, Fusion, and instead gives a user easy access to many destinations: connect once, then dial a number on the radio to choose which network you want. The name says what it does — it offers many destinations (multi-destination), selected by Fusion's group-ID numbering (DG-ID), through one connection point (gateway).
The gateway is a C4FM/Fusion hub that a user links to with a single connection from their radio or hotspot. From that one connection, the user can reach dozens of separate Fusion networks — regional links, interest groups, worldwide rooms — without ever reconfiguring their hotspot. It's single-mode by design (everything is Fusion), but it turns that one mode into a doorway onto a large directory of places to talk.
This is a different idea from a reflector like XLX or URF. Those host conversations inside their own lettered "module" rooms. A DG-ID gateway hosts very little itself — its job is to route you onward to whichever external network you select.
The mechanism is a standard Fusion feature called DG-ID — Digital Group ID. On a Fusion radio, the DG-ID is just a number from 00 to 99 that you can set like a channel. The gateway watches which DG-ID you've selected and connects you to the matching destination.
Dial a number, change the room
Think of it as a switchboard. You connect to the gateway once. Then, on your radio, DG-ID 17 might route you to one reflector, DG-ID 35 to another, DG-ID 99 to an echo test. Change the number and the gateway quietly re-routes your audio to the new destination — no new hotspot setup, no disconnecting and reconnecting. One connection, many rooms, chosen by a single dial.
Because the gateway routes rather than hosts, it scales easily. Adding a destination just means assigning it a free DG-ID number in the gateway's map; the user simply has one more number they can dial. The same design works whether the directory holds five destinations or fifty.
C4FM-JET is a working Multi-Destination DG-ID Gateway. A Fusion operator connects to it once and then has a directory of 55 destinations on tap, each mapped to a DG-ID number. A small selection:
| DG-ID | Destination |
|---|---|
| 17 | East Coast Reflector |
| 20 | FreeSTAR International |
| 23 | HubNet UK |
| 34 | Pi-Star Chat |
| 35 | QuadNet |
| 42 | Texas DFW |
| 54 | WPSD Project |
| 99 | Parrot (echo test) |
From the operator's seat, it's effortless: link to C4FM-JET, spin the DG-ID to the network you're in the mood for, and start talking. Want a different group an hour later? Change the number. The full map runs to 55 named destinations spanning regional U.S. links, UK and worldwide rooms, and special-interest nets — all reachable from the one connection.
A DG-ID gateway is assembled from established open-source Fusion tools rather than custom software. The reflector that users connect to is pYSFReflector, and the routing is handled by DGIdGateway (part of the YSFClients suite), which maps each DG-ID number to its destination network. An echo/parrot service provides the test channel. None of these pieces are mode-bridging or transcoding — everything stays in C4FM the whole way through, which keeps the gateway simple and reliable.
XLX and URF are multi-mode reflectors; the fanout bridge joins different modes through shared audio. A Multi-Destination DG-ID Gateway is the single-mode specialist of the group: it doesn't bridge modes at all, it routes one mode — Fusion — to many destinations, chosen by a number on the radio. For a Fusion operator, it turns a single connection into a directory of the digital voice world.

A DG-ID gateway is built entirely from established open-source Fusion tools. The DG-ID routing is handled by DGIdGateway, part of Jonathan Naylor's (G4KLX) YSFClients suite and purpose-built for exactly this — using the radio's DG-ID setting to select among Fusion networks. The reflector users connect to is pYSFReflector, the Python YSF reflector by IU5JAE (derived from G4KLX's original YSFReflector). The DG-ID gateway concept is standard Fusion infrastructure; what's original here is the curated C4FM-JET destination directory and its operation by N6JET, set up in collaboration with Anthropic's Claude.
