WYAY is running pilot---Sometimes. It appears the key the pilot on and off depending on what content they have on air. Spots=Pilot On. Mikes=pilot off.
Sometimes the pilot is on with non spot material, such as weather and traffic.
So they're toggling the stereo pilot based on the content? Interesting--never heard that done before. Not sure what that gets them--is the content stereo?
But that would explain why the stereo indicator on my radio keeps going on and off.
