⚠️ Note: Currently in active development. Some features are still being implemented.
Create channels, manage contacts, and program your radio—all from your browser.
- Direct USB Connection - Connect your DM-32UV via Web Serial API (no drivers needed)
- Read & Write - Full codeplug read/write support
- Live Validation - Real-time frequency and configuration validation
- Smart Import - Location-based channel wizard using repeater databases
- Bulk Editing - Powerful table interface for editing multiple channels at once
- Codeplug backup - Save and load a full codeplug as a
.neonplugfile (zipped JSON) - Chirp CSV - Import and export channels in CHIRP CSV format; custom CSV import also supported
- Auto-Configuration - Automatic offset, CTCSS, and color code detection
The .neonplug file is a zipped JSON archive. You can unzip it to inspect the contents in a semi-human-readable way (e.g. codeplug.json inside the zip). Editing the JSON directly is not recommended—use NeonPlug’s import/export and in-app editing instead to avoid invalid data or corruption.
- Digital Contacts - Manage DMR contacts with full talk group support
- RX Groups - Create and organize receive groups
- Scan Lists - Configure scan lists across zones
- Cyberpunk Theme - Eye-catching neon UI that's both beautiful and functional
- Responsive Design - Works seamlessly on desktop and tablet
- Dark Mode Native - Easy on the eyes during long programming sessions
Just visit neonplug.app in a Chrome-based browser (Chrome, Edge, Opera, Brave). No installation needed!
Requirements:
- Chrome, Edge, Opera, or Brave browser (for Web Serial API support)
- Baofeng DM-32UV radio with USB cable
You can use NeonPlug without an internet connection. From the live app:
- On the startup screen, click Download offline version (ZIP)
— or open Settings → About and click Download Offline Version (ZIP). - Save the ZIP, unzip it, and open neonplug.html in your browser.
The file is a single, self-contained HTML (all assets inlined). No server or network required; Web Serial for the radio still works when the file is opened locally.
