The Nodes
VHF Gateway

Interface | CM108 Soundcard - modified |
Radio | FT-1500M @ 5W |
Frequency | 144.900MHz |

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)

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.

This one is to use for tests and experiments….
Friday 6th June 2025
Make a 2nd DMR Bridge to monitor DVSPh TG733 “MilNet”
- Made a new private node
1398
- Connect
481482
to internal private1398
- 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 Node481482
in “Monitor” mode.
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
Monday 9th June
Change this DMR bridge to Brandmeister TG23551
This is the Scottish Multi-protocol
Talkgroup
