What is VoxDMR? The short explanation is that it is a free app for Android, Windows and Linux that will allow you to get on DMR without a radio.
The longer explanation is:
VoxDMR is a free, hotspot-less Digital Mobile Radio (DMR) software client that allows licensed amateur radio operators to connect directly to DMR networks without a physical transceiver or hardware hotspot. Developed by J. Calado, the application runs on Android, Windows, and Linux platforms, transmitting digital voice directly over the internet.
Core Mechanics & Features
VoxDMR works similarly to older software clients like DroidStar but offers a refreshed user interface and modern protocol features.
- Protocol Integration: It utilizes the Rewind protocol to establish direct communication links with master servers.
- Network Support: Licensed hams can communicate across multiple major networks including BrandMeister, TGIF, DMR+, and FreeSTAR.
- Audio Encoding: Uses software-based AMBE+2 vocoder technology to compress, process, and clean real-time digital voice audio.
- Hardware Compatibility: It supports dedicated Android network radios (such as the Inrico S200 and T320) by mapping physical Push-To-Talk (PTT) side buttons.
Step-by-Step Configuration Strategy
To activate and use VoxDMR, operators must possess a valid amateur radio license, an active DMR ID, and network access passwords.
1. Software Installation
- Android: Download the app via the Google Play Store or obtain the official APK release from the VoxDMR GitHub Repository.
- Windows: Install using the standard installer package from the Official VoxDMR Webpage or execute the command
winget install jcalado.VoxDMRin the Windows Terminal. - Linux: Deploy the native Linux package provided on the official software main page.
2. Vocoder Setup
Upon the first launch on your device, download and initialize the digital vocoder file inside the application menu to activate audio processing.
3. Server Registration
- Open the connections profile menu by tapping the three-line configuration menu icon.
- Create a new connection profile and populate the mandatory identity fields:
- Call Sign (e.g., ZS1I)
- Radio ID / DMR ID
- Hotspot / Security Password (configured beforehand in your Self-Care dashboard on BrandMeister or TGIF).
- Select your exact target server location (e.g., BrandMeister UK, TGIF United States) from the dropdown menu and hit save.
4. Initiating Contact
Tap the profile to connect. A green visual indicator confirms a successful connection. Once connected, input your desired Talk Group (TG) number or select a group from your favorites list to start monitoring or transmitting audio.
