Sculk Radio
by Gjorgdy
Sculk Radio adds sculk-based blocks that carry audio, voice chat and redstone signals between points in a world, linked by a tuned amethyst antenna.
What it does
Sculk Radio lets players build networks that stream music, voice chat audio and redstone power across a world. A transmitter node sends a signal to one or more receiver nodes, and relays pass it along in between, so a network can reach well beyond the range of a single block. Antennas join separate networks together over a shared frequency, and an antenna has to be placed directly above a relay. Relays repeat the stream and can be spaced up to 16 blocks apart by default.
The mod is server-side only: the server runs it, and players join without installing anything. It requires Fabric API and is published for Fabric alone, with seven release versions 1.21.9 – 26.3 and the latest file 1.0.0+26.3 dated 2026-09-18. The source code is open source under the Apache License 2.0, and optional links to AudioPlayer, Fzzy Config and Simple Voice Chat extend the audio and configuration side.
Key features
Audio streams
Radios stream a music disc or a vanilla voice chat signal from a jukebox or sculk shrieker without playing it locally.
Redstone streams
A radio outputs the highest redstone signal it receives, either as a normal or an analog strength, across the network.
Microphone and speaker
A microphone picks up nearby players within 8 blocks by default, and a speaker plays what the network carries.
Tuned antennas
Right-clicking an antenna with an amethyst shard tunes it to a frequency, which can be copied or randomized.

Use cases
Music across a base
A jukebox feeds a network so music plays in distant rooms through speakers placed where needed.
Remote redstone control
A transmitter sends a redstone signal to a target block far from its source, without long runs of wire.
Who it’s for: Server owners who want music, voice or redstone to reach across a large world, and builders creating sculk-themed contraptions.
How it compares
CozyRadio Mod is a client and server mod released under the CC0 1.0 Universal license, built for 1.21.11 only, so it covers a narrower version range. Echoing Sculk Sensors is a client and server mod under the MIT License, open source, for 1.21.6 – 26.1.1. Simple Voice Chat Radio is server-side only with Fabric and Quilt files for 1.20.1 – 26.1.2, but it is not open source.
