OP here. I was listening on a decent sounding car audio system (Not great, but decent. It came with the car; the same way most drive-time listeners would hear radio) in various locations around L.A. County. Sorry I'm not able to describe this better, but this is definitely not my area of knowledge! That's why I was hoping somebody in the market who knows this stuff would listen and tell me if I'm losing my mind. Best way to describe what I heard would be if you put a boombox in the bottom of a big metal garbage can. Especially annoying when the jock was talking, and bad on iHeart's KFI. I just don't hear this sound on stations in other markets.
Wavo, you said that aggressive Voltair setting can be heard on-air. What would that sound like exactly?
