What does it do? I tried to hook it to the radio beacon to hear the settlement radio, like the Castle, and it just hums...

Ya its useless that's all it dose is that hum

It's so annoying...

as i know it, its like a note block from minecraft.

it plays a note and thats it... program it from a terminal with several others and you should be able to make music.
