MumRadio Pro

MumRadio is a push-to-talk radio app built for Mumble voice servers.

It gives teams a simple radio-style voice experience: connect to a server, choose a channel, and hold PTT to transmit. MumRadio is designed around one-way, simplex communication, so it feels familiar for users who are used to handheld radios, dispatch channels, and field communication.

Features include:

- Push-to-talk voice transmission
- Mumble server support
- Channel-focused radio interface
- On-screen PTT button
- External and Bluetooth PTT button support
- Automatic reconnect after connection loss
- Optional spoken channel announcements
- Client certificate support
- Adjustable speaker volume and microphone gain
- Optional voice recording
- Battery usage tools for active radio sessions
- Two and Three tone paging alerts
- Monitor a separate channel when in another channel

MumRadio is intended for virtual radio workflows where fast, clear, intentional voice communication matters. It does not use voice activation or continuous transmit; microphone audio is captured only for push-to-talk transmission and related user-enabled radio features.

A Mumble server is required to use MumRadio.
