A mod that allows you to broadcast note block songs across your Minecraft world.
Features
- Radio: Plays music transmitted by nearby transmitters.
- Transmitter: Transmits music played by nearby note blocks when powered.
- Minecart with Transmitter: Same thing as the transmitter, just in a minecart. Activate it with an activator rail. Great for long note block songs!
- Radio Jammer: Used for trolling. Just transmits a random note every tick when powered.
- Relay: Relays notes on a specific channel when powered.
Anything with a channel (transmitters, radios, etc.) can have its channel changed by shift+right-clicking it.

- Lossy Range: The range added onto the lossless range at which a transmission is received, but some notes may be lost. (Default 64)
- Channel Count: The amount of channels available to select from. (Default 16)
- Relay Hop Limit: The maximum amount of relays a signal can hop between to reach a radio. (Default 8)
