I have had an XLX Multiprotocol Reflector running for almost 11 months now. It had no hardware transcoding, therefore only DMR and Fusion could communicated on the same module. A module is like a room in Fusion-speak, where several nodes can connect and communicate.

D-Star could not be transcoded using this method. So I purchased two DVMega DVStick 3000. There are small usb stick devices that can transcode various digital voice formats. I have created a transcoding server at my QTH, initially using a Raspberry-Pi 4B. It was quite a process to get it up and running, but so far, DMR to Fusion and back is still working. As I do not have a D-Star radio, I have no way to test D-Star at the moment.
Steve, KA1CNF indicated he will help me test soon, so hopefully D-Star is working and we will soon be able to cross-communicate between D-Star and DMR and Fusion without much hassle.
The XLX927 reflector is still located on a cloud server, so we will be observing whether there are any latency issues with the transcoding server being remote.
If by chance you read this before April 4, 2025 and have a D-Star radio and a hotspot, you may attempt to connect to XLX927 Module B. It might be better to contact me at k2as at outlook.com to arrange a test.
A reminder about the existing capabilities, I have XLX927 Module B bridged to YSF00927 and Wires-X Room 21707, which the 145.29 W2XRX repeater is also usually connected to.
Again, here is a link to the XLX927 Dashboard: http://k2as-ref.xyz/index.php
As things become tested and working correctly, I will publish a more detailed description of the capabilities and connecting methods.
We also might some some interesting news about a another local repeater connection in the near future.
