AllStar Linking

The Nodes

VHF Gateway

Platform Raspberry Pi 2 Model B Rev 1.1
InterfaceCM108 Soundcard - modified
RadioFT-1500M @ 5W
Frequency144.900MHz
Allstar Node 481480
Echolink GM4SLV-L : 886089
Dashboard http://gm4slv.plus.com:42110/

The initial node, described here → A new start 2025 got too cumbersome after adding DMR Bridging, along with handling Echolink.

I decided, since I had a few spare Raspberry Pi boards doing nothing much, to split the DMR Bridging to a separate node.

I removed the DVSwitch bridging from the VHF Gateway node and changed its node ID to 481480 (NNX)

/etc/asterisk/echolink.conf

DMR Bridging Node

Platform Raspberry Pi 3 Model B Rev 1.2
Allstar Node 481481
Dashboard http://gm4slv.plus.com:42111/

This one is for running DVSwitch to bridge to (at the moment) TGIF TG2354429 (my so-called ID Talkgroup )

I added the DVSwitch software, in the same way described here A new start 2025 and decided to bridge to TGIF instead of Brandmeister.

I also decided to use the md380_emu emulator for the AMBE transcoding.

Test Node

Platform Raspberry Pi 2 Model B Rev 1.1
Allstar Node 481482
Dashboard http://gm4slv.plus.com:42112/

This one is to use for tests and experiments….

Experiment 1

Friday 6th June 2025

Make a 2nd DMR Bridge to monitor DVSPh TG733 “MilNet”

  • Made a new private node 1398
  • Connect 481482 to internal private 1398
  • Set up DVSwitch MMDVM_Bridge & Analog_Bridge
    • MMDVM set to use Hotspot ID 235442998
    • Options=StartRef=4000;RelinkTime=0;UserLink=0;TS1_1=733;
  • Connected MMDVM_Bridge to DVS_Ph F server - linked to TG733
  • Main VHF Gateway Node 481481 connected to Test Node 481482 in “Monitor” mode.
Experiment 2

Saturday 7th June 2025

Change this DMR bridge to TGIF TG2354435

This is the ID Talkgroup for my 2nd DMR ID

  • MMDVM_Bridge set to connect to TGIF, using my alternative DMR ID, as hotspot 235443598
    • this requires the correct User Security passphrase for 2354435
  • Also confirmed operation with MMDVM_Bridge connecting as normal 235442998 (my “usual” DMR ID with SSID=98)
  • Analog_Bridge set to use TG2354435
Experiment 3

Monday 9th June

Change this DMR bridge to Brandmeister TG23551

This is the Scottish Multi-protocol Talkgroup

Experiment 4

Monday 9th June

Change this to NXDN Bridge to TG23551
