Clarkey submitted an updated version of his Ambient Radio Chatter script which he released on the BI forums.

Quote Clarkey :
A script that adds ambient radio chatter to ArmA 3 vehicles.

Features:

• Adds to the "battlefield ambiance" of A3.
  
• Easy customization
  
• Only uses tracks from the A3 Alpha so no addons are required.
  

Changelog:
• Added: Volume setting (see customization)
  
• Changed: Default volume set to 0.2 (sounds less intrusive now)
  
• Fixed: Script now terminates when player exits vehicle.
