RPN Reflector XLX147, Talkgroup TG24098 & Internal DMR
    About the WHY and HOW of RPN's own D-Star & DMR platform

The Reflector is meant to be a special interest meeting point for Robust Packet Radio & PACTOR operators.

Although the awareness is present that the ham radio community is divided when it comes to digital voice modulation and the use of internet it nevertheless might turn out to be quite helpful for our world wide coordination of the net.

• It opens the possibility to spot a HF RPR APRS station at far distance but at the same time having a chance to talk to each other immediately if D-Star or DMR is on board.
• It gives sysops the chance to have a quick coordination of IGATEs & DIGIs.
• It offers a "local" standby "frequency" for the RPN community.
• It gives newcomers a possibility to receive first hand information and getting in tough with us.

If you want to use the reflector, you might need the following data to update databases.

reflector   DCS147          
reflector   REF147          
reflector   XRF147           NOT XLX147!
                                        (XLX is a name of a reflector system, while DCS, REF & XRF are protocols)

static IP

If you have a DVMEGA hotspot (D-Star Commander, MMDVM, etc.) open the terminal window and go to
nano /usr/local/etc/DCS_Hosts.txt
and insert
in the right sequence.

Or download fresh host lists from the following (ARRG) source
(left click to see, right click to save)

(DCS) DCS_Hosts
(XRF) DExtra_Hosts
(REF) DPlus_Hosts

Meanwhile transcoding works from each of the 3 D-Star protocol types (DCS, REF & XRF) towards DMR and back on the XLX147 reflector. The transcoding solution is a project of DF2ET, Florian & Mathis, DB9MAT and is known as AMBE3003USB. It provides 2 channels to the XLX147 reflector.

The DMR Talkgroup TG24098 was exclusively created for RPN and can be selected dynamically on any DMR repeater/hotspot and/or get inserted in the Brandmeister self-care area as fixed time slot choice. Beside the ability to communicate DMR-to-DMR the Talkgroup is permanently connected to the XLX147A reflector room.

Internal DMR

Internal DMR means to use DMR without BrandMeister or DMR+ connection. This is possible because XLX is able to handle DMR including connection to the different modules A to Z.

Only change the DMR Master Address and the Port in your hotspot and reboot. Find below the example in the .ini-File of a MMDVMHost device.


[DMR Network]
# Address=master1.bm262.de
# Port=62031
# Local=62032
# Options=
# ModeHang=3

Now you can select the different modules by selecting TG4001 to TG4026 with a short PTT.
Then go back to TG9 and make your call.

To change the module select TG4000 (disconnect) and then a different TG4001 to TG4026 followed by the switch back to TG9 for the QSO.

Here the matching TG and XLX modules:

TG4001 - XLX147A
TG4002 - XLX147B
TG4003 - XLX147C
TG4004 - XLX147D
TG4005 - XLX147E
TG4006 - XLX147F
TG4007 - XLX147G

The solution is fully via LTE/4G internet connection in Sweden. But public IP addresses are not available in mobile networks. Therefore a single static IP address is hired from Portunity.de with a traffic of maximum 50GB per month which is about 5 times more than a reflector needs. An exclusively for this purpose operating TP-Link M7350 feeds the Raspberry Pi 3 which has an OpenVPN configuration to make the IP addressable.
