What is a XLX Refector?

Since the dawn of D-Star, there have been a few reflectors and networks built to support this digital mode. XLX is the newest edition of reflectors that allows you to spin up your very own D-Star or DMR, or YSF reflector. Reflectors like REF and DCS, already have servers in place that you request access to use as an admin. XLX is a piece of software originally created only for D-Star and DMR that runs on a Linux server that can be linked to from other repeaters and hotspots much like a hub and spoke design. One of the special things about XLX reflectors is they do not require registration on the D-Star trust system to use them. New D-Star users can simply link and start talking. XLX sets itself apart from the other reflectors in the D-Star world because its a ‘multi-mode reflector’ meaning, it has the ability of allowing any of the D-Star linking protocols (DPLUS, DCS, D-Extra, etc) to connect to it. Also as of January 2020, XLX supports System Fusion natively. By adding another piece of software, AMBEd, and hardware vocoder usb-dongles, it can act as a transcoding server allowing other modes to talk together.

Some features include:

  • One reflector 3 modes out of the box: D-Star, DMR, and YSF.
  • Real Time Dashboard showing last heard and current ongoing QSOs through the reflector.
  • Ability to peer with other reflectors, and networks like Brandmeister.
  • Cross digital modes using a hardware vocoder; D-Star can talk to DMR or D-Star to analog or Fusion, etc..
  • Supports 26 modules/rooms A-Z.
  • Opensource!!

 Linking Protocols

 

Network Ports

The following are ports used for XLX. Be sure they are open and accessible depending on the services you need:

  • UDP: 10001-10002 — XLXd (peering)
  • UDP: 30001 — DExtra Protocol
  • UDP: 30051 — DCS Protocol
  • UDP: 10100-10199 — AMBE Transcoding
  • UDP: 42000 — YSF Protocol
  • UDP: 20001 — DPlus Protocol
  • UDP: 62030 — DMRM / MDVM (DMR Gateway)
  • TCP: 80/443 — Web Dashboard
  • TCP: 22 — SSH (or your chosen port)

What is a transcoding server?

A transcoding server is a computer running special software that can input one digital mode and output a different mode. Whether you know it or not, the bain of the digital voice existence today is the fact, digital voice modes can’t communicate with each other. If you have a DMR radio sitting next to a D-Star radio, the two can only communicate via their analog mode, not their respective digital mode. By using simple software like Pi-star, we can configure it to connect to nearly any server, both online and offline, and this includes a transcoding server. A server can be installed in the “Cloud”, where it can be accessed from all around the world allowing hams to easily connect. A server can be installed at a single tower site to bridge a local community of radio operators. For example, DMR on Frequency 1, D-Star on Frequency 2, Yaesu Fusion on Frequency 3, at one or multiple high profile repeater sites. The list of applications go on..
