... how come? Is there a solution for adjusting the loudness of the ATC chatter? But no one has responded to any of these posts...

pre-recorded chatter, or ai chatter?

I think it's both. While I love the chatter and the realism it adds, I like to be able to control it and bring it down a bit. With that said, I certainly would not want to see the volume reduced to where it cant be adjusted by the user in RC5 but rather a volume control where we could adjust to our liking. By the way, the chatter is absolutely excellent. I dont know what I was thinking being content with Microsoft's ATC comm. Boy oh boy! RC4 is a load of fun and has taken the simming to a whole new level. someone once said they heard the ATC prerecord traffic loop but I havent yet - I swear it seems like its actual communications. OKay, I'll stop.
