## About The Pull Request
Now talking into radio and hearing radio messages produces a sound.
Using LOUD-MODE makes a unique sound.

**YOU CAN DISABLE IT IN THE GAME PREFERENCES**
## Why It's Good For The Game
People REALLY tend to miss radio messages, especially from the heads.
This makes it so they can hear when some interesting or important
chatter is going on.

Unless all of the heads of staff decide to dispute in the Common,
subordinates will start noticing messages from their bosses in their
channels more often.

Also, these sounds are tickling my ears, in a good way.
