Radio
Radio lets players broadcast sound across the world on configurable frequencies using transmitters, receivers and handheld units.
What it does
A Radio Transmitter broadcasts microphone audio, or the music of nearby jukeboxes, over a frequency chosen between 88.0 and 108.0 MHz. A Radio Receiver plays incoming transmissions out loud, and a Portable Radio does the same from the player's hand. Signal strength depends on how closely the receiver's frequency lines up with the transmitter's and on the distance between them.
Transmitters need lightning rods stacked above them to reach full range, and each additional antenna improves the signal. The mod works with Simple Voice Chat for broadcasting and with AudioPlayer for custom music discs, which Audio Player Support can route through the radio. Radio requires AudioPlayer, Fabric API, SGL (Super GUI Lib) and Simple Voice Chat. The server and every player need the mod installed. Builds exist only for Fabric, for 1.21.11, released under All rights reserved, so the code is not open source.
