I first noticed it a few days ago -- and only during the in-studio segments of the news broadcasts. I've since noticed it on the morning and evening broadcasts. It was still there on tonight's broadcast but only at a few spots... like when they moved off to the side of the news desk for the piece on e-cigarettes. Perhaps I'm hearing a loud HVAC system in the background, or a wireless microphone that's acting up.
