Radio

A Minecraft Fabric mod that adds functional radio transmitters, receivers, and a portable radio for wireless audio broadcasting via Simple Voice Chat.

Features

• Radio Transmitter — broadcast microphone audio or jukebox music wirelessly over configurable frequencies
• Radio Receiver — receive radio transmissions and play them out loud
• Portable Radio — handheld receiver that plays audio directly to you
• FM Frequency System — 88.0–108.0 MHz with signal quality based on frequency alignment, distance, and signal strength
• Antenna Requirement — transmitters need lightning rods stacked above them; more antennas = better range and signal
• Noise & Interference — static noise when out of range, interference from competing transmitters on nearby frequencies, smooth transitions
• Jukebox Broadcast — captures audio from nearby jukeboxes and transmits it through the radio
• Audio Player Support — optional AudioPlayer mod integration for custom music discs
• Dual Audio Sources — microphone and disc inputs with independent volume controls
• Capture Radius — configure how far the transmitter listens for nearby players (microphone) and jukeboxes (discs)
• Note Particles — receivers show note particles when playing a clean signal
• VU Meter — visual audio level indicators in the GUI
• Separate Volume Categories — independent volume sliders for radio and portable radio in Simple Voice Chat

Crafting

Usage

Radio Transmitter

1. Craft and place a Radio Transmitter
2. Stack lightning rods above it (continuous column) — more rods = better signal
3. Right-click to open the GUI
4. Set frequency (88.0–108.0 MHz), range (50–5000), signal strength (1+)
5. Toggle microphone and/or disc mode with independent volume sliders
6. Set capture radius (3–50 blocks) — how far it listens for players/jukeboxes
7. Speak nearby (within capture radius) while the transmitter is powered to broadcast

Radio Receiver

1. Craft and place a Radio Receiver nearby
2. Right-click to open the GUI
3. Set frequency to match a transmitter, adjust volume and distance (5–50 blocks)
4. Powered receivers automatically play any signal on their frequency within range

Portable Radio

1. Craft a Portable Radio
2. Right-click to toggle power ON/OFF
3. Shift + right-click to open the GUI and set frequency and volume
4. Keep it in your inventory (any slot) — it will automatically connect when powered

Frequencies & Signal

• Range: 88.0 – 108.0 MHz (FM broadcast band)
• Matching transmitters and receivers on the same frequency = clean signal
• Nearby frequencies produce interference noise proportional to the difference
• Signal quality depends on: frequency match, distance, transmitter signal strength, and competing transmitters

Requirements

• Minecraft 1.21.11
• Fabric Loader ≥0.18.5
• Fabric API
• Simple Voice Chat
• Super GUI Lib
• AudioPlayer
