About this Mod
Walkie Talkie 
A Minecraft Fabric mod that adds functional walkie-talkies with real voice communication via Simple Voice Chat integration.

- 16 Channels (1–16) — select any frequency through the in-game GUI
- ON/OFF Toggle — enable or disable your walkie-talkie at any time

- Fake Sound System — broadcast OGG audio files through a radio channel using commands
- Custom Sounds — power on/off clicks and ambient static noise play during transmissions

Walkie Talkie server crashes on startup – what to do?
Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.11). You can switch loaders with one click in the panel.
Is Walkie Talkie compatible with fabric?
Walkie Talkie officially supports fabric for Minecraft 1.21.11. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with Walkie Talkie – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Walkie Talkie consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
