Connection guide — XLX159 Reflector Hub

Server information

The values you need to configure your radio, hotspot, or client. Each row has a copy button.

Address (hostname)	`xlx159.duckdns.org`
D-Star port	`30001`
DMR port	`62030`
YSF port	`42000`
M17 port	`17000`
DCS port	`30051`

Module letters

Each mode has a letter. Use it after the XLX159 prefix in your URCALL or destination field.

Letter	Mode	URCALL for D-Star
A	D-Star	`XLX159AL`
B	DMR	`XLX159BL`
C	YSF	`XLX159CL`
D	P25	`XLX159DL`
E	NXDN	`XLX159EL`
F	M17	`XLX159FL`

Choose your connection method

Walkthroughs for the four most common setups. Pick the one that matches what you are connecting.

Pi-Star / WPSD hotspot setup

For a Pi-Star or WPSD hotspot running on a Raspberry Pi or similar. This is the most common configuration for a home station.

Open the Pi-Star dashboard Browse to http://pi-star.local or the IP address of your hotspot. Log in if you have set a password.
Enter configuration mode Click Configuration on the left. If prompted, enter your password.
Set the host on each enabled mode For D-Star: set Startup Host to xlx159.duckdns.org and Startup Module to A. For DMR: set DMR Master to XLX159_BM and the port to 62030. For YSF: set YSF Host to xlx159.duckdns.org with port 42000.
Configure the URCALL and module For D-Star, set Module to A and Pi-Star will fill the URCALL as XLX159AL. To switch modules, change the last letter: XLX159BL for DMR, XLX159CL for YSF.
Set frequency and power Enter the frequency for your local hotspot, set the power to 5-10 mW for indoor use, and configure any duplex offsets if your radio is full-duplex.
Apply and reboot Click Apply Changes at the bottom, then reboot the MMDVMHost service from the Dashboard page. The hotspot will register on the reflector in 10-30 seconds.

Tip: If the dashboard shows "MMDVMHost not running" after reboot, check the system log from the dashboard for the actual error. The most common cause is a typo in the hostname or a firewall blocking outbound UDP on the mode port.

G2 Link (ircDDB) for D-Star

Use this if you have a repeater or hotspot that connects to the D-Star network through ircDDB rather than DCS.

Log into your ircDDB gateway. Either the local dashboard or the remote gateway at xlx159.duckdns.org:30001.
Open the gateway configuration. Set the ircDDB server to xlx159.duckdns.org.
Register callsign if needed. If the gateway is not yet registered, register it through the ircDDB dashboard.
Set the default URCALL. Use XLX159AL for module A, or change the last letter to switch modules.
Apply and verify. The gateway should register on the reflector within a minute. Check the dashboard for the connection status.

Tip: ircDDB and DCS can coexist. If you want to bridge to DCS as well as ircDDB, leave the DCS server set to the default and add the ircDDB host as a second gateway.

Linked repeater

For a full-duplex DMR, D-Star, or P25 repeater that will be permanently linked to XLX159.

Configure the repeater controller. Set the host to xlx159.duckdns.org and the appropriate port for your mode (30001 for D-Star, 62030 for DMR, 42000 for YSF/P25/NXDN, 17000 for M17).
Set the static talkgroup or module. For DMR, set TG 159 on TS2 as a static link. For D-Star, set URCALL to XLX159AL.
Configure user access. Set the repeater so that local users can transmit through the reflector (default for most repeater controllers).
Test with a handheld. Key up from a local radio and verify that audio appears on the reflector status (if you have a way to check) and that you can hear the reflected audio on another receiver.
Document for your users. Post the connection info in your repeater's documentation so users know what to expect when they key up.

Tip: Most repeater controllers support a fallback link. Set a second URCALL (e.g. REF001CL for the REF001 C reflector) so the repeater falls back to a working reflector if XLX159 is offline.

Software client (DroidStar, BlueDV, etc.)

For connecting from a phone or computer without a radio.

Install a client. DroidStar for Android, BlueDV for Windows or Linux, or any other client that supports your mode.
Create a new connection profile. Set the host to xlx159.duckdns.org and the port for your mode. DroidStar will auto-detect the module from the URCALL.
For DroidStar specifically: Set the Reflector to XLX159 and the Module to A (or whichever you want).
For BlueDV: Use the AMBE server built into the client, or set it to None if your sound card supports AMBE natively.
Test with a call. Key up and listen for return audio. If the audio is one-way, check that the AMBE server is configured correctly.

Tip: DroidStar is the most actively maintained amateur digital voice client for Android. The free version supports D-Star, DMR, and YSF; the paid version adds P25 and NXDN. For M17, use the M17 Reflector app on Android or m17-cli on Linux.

Quick reference

Single page you can screenshot or print. Everything you need to put XLX159 on the air in one minute.

Hostname

xlx159.duckdns.org

Default URCALL

Pick a module and use XLX159 L (replace L with A–F). For example, module A: XLX159AL.

Default DMR TG

TG 159 on TS2 routes to module B and is bridged to the rest of the reflector.

YSF room

YSF#15900 to land on module C. Other FCS rooms are reachable from the bridge.
