English Help for XLX508


The XLX508 was originally set up to provide the East Westphalia area with a gateway that stations that use DMR can talk to stations in DStar.

Later there was the possibility that stations in C4FM can also speak with the DMR and the DStar stations.

In the course of time, the individual modules were configured and certain functionalities or uses configured accordingly.

Module A = International Here you can hear traffic from various other XLX gateways that have connected Module A to the XLX508. This module should be used for international connections if possible.

Module D = The Swiss module. The entire Swiss digital standard radio communication takes place here. The XLX229 D is connected to the XLX508D. All Swiss DStar repeaters are linked to the XLX229D and accordingly you can hear it on the XLX508 D and you can speak directly there and will then be heard on all Swiss repeaters.

Module E : This module is intended for the exchange of images. The Icom IC9700 as well as the ID-4100 and the ID51Plus2 in connection with the corresponding Icom software offer the possibility to exchange pictures with each other. Module E is connected to the XLX227E, the XLX555E, XLXCAT and the XLX802E. More peerings should follow, but depends on the sysops of the XLX servers.

Module G = Here the bridge to DMR and C4FM is connected. This bridge can be reached via DMR in the TG26446 in the Brandmeister Netz and via the C4FM Room DE OWL (YSF19829). Here DStar, C4FM and DMR radio operators can conduct QSOs together. So-called transcoding takes place more or less in real time, so that a transmission can always be heard in each of the three operating modes.

Module J = this is the reflector in Dstar for the East Westphalia area. Originally intended as an alternative for DCS001J, but since the DCS001 has been causing problems for some time now, module J has been used very recently.

What's behind it?

The whole functionality sounds very complicated at first, but it is not really.

Here is a short explanation of how all the offers of the XLX508 work and what is behind them.

The XLX508 and the YSF19829 run on a server that is located in Frankfurt and is connected to the rest of the Internet via various connectivities.

A 10Gbit line is available, which in turn is shared with other services.

We have a guaranteed upload and download speed of around 1Gbit each.

The XLX508 is the heart of the whole system and establishes the various connections to other services. On the one hand this is the Brandmeister Master 2622, which provides the connection for the DMR access from the TG26446, on the other hand it also provides the connection to the YSF19829 (DE OWL), which runs on the same server.

Then there is the functionality of transcoding, this is the translation of the different modes into the other modes. For this I run a small mini computer at home with a so-called LePotato with Linux, to which an Ambe 3003 and an Ambe 3000 are connected.

The Ambes codecs deliver a total of 4 channels; which does the translation from one mode to another. This transcoding is a so-called hardware transcoding and is done in almost real time. Thus, 2 channels are always required to switch from e.g. Translate (transcode) DMR to DStar.

This means that transcoding can take place simultaneously on two modules.

The transcoding from C4FM to DMR and vis versa is done on the software side, since DMR and C4FM are very similar and no chip (no hardware) is required for this.


So much for the operation of the XLX508.

Now we come to the possibilities and what you have to do to use the XLX508.

You need a radio that can do DMR or DStar or C4FM, nothing else in terms of hardware.

You go to the nearest repeater and connect to the XLX508 in DStar / to the YSF19829 in C4FM / or with the TG26446 in the fire department network in DMR.


How do you do that?

Let's start with DStar:

There are different options in DStar, depending on how the personal hotspot / nearby DStar repeater is configured.

You set your radio to the appropriate frequency and set the parameters to match the hotspot:

Let's take DB0HFD as a template:

Frequency 438.525 storage minus 7.6Mhz

RPT1 ; DB0HFD B & ldquo; & nbsp;

RPT2 ; DB0HFD G & ldquo;

In To Station you need to fill: Use Repeater CQCQCQ & ldquo;

With the DTMF tone; you can check where the repeater is linked to.

The DTMF keys can be used to call up the XLX and the corresponding module either directly or via a stored tone sequence. Depending on how the repeater is configured, either A50810 must be called, for example to call module J.

Then comes the message: & bdquo; Connected to X L X 5 0 8 J & ldquo;

If the repeater is configured differently and it does not work, you can try to call the XLX508J with the DTMF series D50810.

This message should then come:"Connected to D C S 5 0 8 J come.

If that doesn't work either, the file that makes the addresses of the individual gateways available to the repeater has not been brought up to date for a long time.

There is also a third option, in which you enter the XLX508 with the respective module in your Your Callsign list in the radio.

As an example for the module J

Name: XLX508 OWL

Call Sign DCS508JL or alternatively if XLX support on the repeater is activated XLX508JL

Then & bdquo; To Station & ldquo; select the corresponding entry to link the repeater / hotspot.


Now to DMR:

In DMR you have to be on a repeater / hotspot in the BM DMR network.

The radio must have programmed a channel that corresponds to the frequency of the hotspot / repeater. The TG 26446 must be selected to access module G, where cross-band operation is possible.


DMR directly on XLX508:

There is also the possibility to reach each of the modules directly in DMR.

To do this, the hotspot or the repeater via which you are working would have to be connected directly to the XLX508 and the corresponding module.

The whole functionality sounds very complicated at first, but it is not really.

A requirement must be met by PI-Star. Version 4.1 RCXXX or higher must be installed. You can find this here: PI-Star 4.1 RC7

To do this, the hotspot or the repeater via which you are working would have to be connected directly to the XLX508 and the corresponding module.

For this, the hotspot or the repeater must be connected to the XLX508 and then you can call up the respective module via a private call.

A stands for 4001, G = 4007, J = 4010. Simply take the letter in the alphabet and replace it with the corresponding number.

The XLX508 offers a direct entry for DMR.

To do this, the hotspot / repeater must be connected directly to the IP of the XLX508.

PiStar offers a nice function the DMR gateway. There you can configure a BM server, a DMR + server and an XLX server.

If this function of the DMR gateway is activated and the XLX508 is configured there, the hotspot / repeater connects directly to the XLX508 and the correspondingly configured module.

Only one channel for the hotspot / repeater must be configured on the radio and the TG6 must be configured as a talkgroup in the TS2.

The hotspot then works as usual in the BM network. The XLX508 is only addressed if you use the channel with the TG6.

With a Private Call 4000 in the TG6 you can separate the module. With 4001-4026 the module A -; Call Z.

For this, the hotspot or the repeater must be connected to the XLX508 and then you can call up the respective module via a private call.

This works as follows if you work with PiStar:

You log into the configuration via the Pistar web interface.

There you will find the following section in the DMR area:


In the DMR Master field you change from the set value to "DMR Gateway". This is the first entry in the Scroll Down Menu of the DMR Master.

DMR config gateway selection

Then press Save to save this configuration first.

When this is done, the DMR configuration menu is expanded and additional fields appear.


In addition, several options appear for different DMR networks.

In "Brandmeister Netzwerk ID" you enter the master that you otherwise had in the DMR master, usually for DL ​​this is BM_Germany_2621 (or 2622)

With "Brandmeister Netzwerk Enable" you move the slider to the right so that the BM Netz is switched on.

The hotspot is now configured for the BM network and all settings have been made so that the hotspot runs exactly as before.

We leave out the DMR + master, but if someone wants, he can configure it according to his needs and call the corresponding master.

You can access the DMR + network from the radio via the "TG7". The TG7 is the TG9 of the DMR + network.

All private calls must be made via the TG7 in order to then call up a reflector.

Now there is access to the XLX DMR access:

In XLX Master you choose the XLX508.

In the startup module, you select module J to get the XLX508J. All other modules also work accordingly.

The XLX Master Aktiv slider must also be pushed to the right again to activate it.

Then you save the whole thing again and the configuration is done.

To access the DMR XLX508, you have to have programmed the TG6 in the DMR device.

Via the TG6 you can get to the XLX508 without doing anything.

Since a module has been predefined in the hotspot, no "private call" is necessary to call it up.

However, any other module can be reached via a "private call", in which one works with the numbers 4000-4026.

A stands for 4001, G = 4007, J = 4010. Simply take the letter in the alphabet and replace it with the corresponding number.


>> New !!!! - Direct operation in C4FM on the XLX508 - New !!!! <<<

With the release update to version 2.4.0, which was made on April 9th, 2020, operation in C4FM is also possible directly via the XLX508. However, the YSF19829 remains active until further notice and you can just go there and land on the module XLX508G and is also connected to the BM TG26446.

All incoming transmissions in C4FM are now transcoded in DStar and DMR and vice versa of course, all transmissions in DMR or DStar can also be heard in C4FM,

With the appearance of the new host files for PiStar and other applications, the XLX508 is also available in the YSFHost files.

The YSF reflector can now be found as "YSF64446 - XLX508 -XLX508refetor" in the host files. Yes, a "C" is missing, but this is intentional because only 14 characters are possible in the description. If someone has another suggestion, please use the feedback form to submit the suggestion. I will watch it and change it if necessary.

After connecting the hotspot / repeater you are automatically connected to the "J" module, which is the "OWL" module and can also be reached in Dstar and DMR.

The call can also be made via the radio. This in turn differs individually on the radio. The call is made like any other C4FM reflector at the repeater / hotspot.

The XLX508 YSF Reflector has all 26 modules (AZ) and these can be selected using the Wires -X function of a Yaesu C4FM device.

The modules with a peering are listed above in the help and the meanings / "rooms" are named. In the module description these are also listed and "live" always up to date.

The functionality is outlined in the following pictures. Since I don't have a C4FM device, I can only provide a small extract in pictures of how this works. Due to a lack of knowledge about C4FM, I cannot provide a description.

The following pictures were kindly provided to me by Klaus, DL4YCC based on his Yaesu FT2D. Therefore, I ask for leniency that you have to find out for yourself. I can only say, somehow about Wires-X, but that also differs from device to device.

Unfortunately, Yaesu pursues a different device policy and does not do it as Icom did: "If you know one device, you can also operate the others."

Picture Service:

With various Icom devices it is possible to send pictures.

The XLX508E module is prepared for this

Icom G3 gateway:

The XLX508 also offers connectivity for the so-called G3 gateway service for Icom radios. The IC-9700, the ID-4100 and the ID-51 Plus 2 currently offer this possibility. For the IC-9700 you only need your radio, for the IC-4100 and the ID-51 Plus 2 you also need a PC and the OPC2850 cable. The G3 Gateway offers 2 different modes in conjunction with the radio devices mentioned. First the gateway mode and the terminal mode.

The gateway mode provides a direct connection to the XLX508, like a hotspot.

Terminal mode establishes a direct connection to the XLX508 and you can then speak directly into the XLX508 without HF.

The respective instructions for the radio devices provide a description of what needs to be done.

The IP that is required for the Terminal / Gateway mode is: .

However, I can also provide limited support.

Now a little something as a supplement to the operation of the XLX508


These instructions offer most of the functionalities of the XLX508.

If something is missing, I ask for a hint and I will add the function that I have not described.

As soon as there are extensions, they will be added here as soon as possible.

This gateway service is operated by my son Julian and me.

We operate this gateway out of pure self-interest and to open up the possibilities mentioned above to the community of radio amateurs, especially in OWL and all over the world.

If the service does not work at all or only to a limited extent, please send me an email to admin@hb9gfx.ch . But please keep in mind, we are also employed and cannot deliver support 24 hours / 7 days / 365 days a year. We will try to fix a bug as soon as possible if it is brought to us.

I am also looking for someone who can support me with the operation of the server.

It takes a little Linux knowledge and nothing else.

Please also send offers to the above email address

The operation is not free of charge and is supported by Julian and me.

To illustrate what is behind the XLX508.

A server worth around € 700 was created. (used) installed.

The XLXD software is free and was written by Luc LX1IQ.

The YSF gateway was written by Jonathan G4KLX.

The monthly costs for rent, electricity and traffic are around 70 €

The Ambe decoders and the LePotato have about 400 euros. cost.

Thus, the investment costs for the gateway without the surrounding (sockets, router, switch, etc., which is just needed to operate servers in a data center), what you still need, are about 1100 euros. plus about 70? monthly (840 € / year) at running costs. & nbsp;

Donations are welcome.

These can be transferred to the Paypal account DG9BDI / HB9GFX as family / friends.

All donated funds flow 100% into the operation and expansion of the gateway.

Thank you very much


73 and have fun with the services of XLX508
