I have noticed the same thing. I've also noticed their signal seems to be a bit stronger. In Vidalia, they seem to come in clearer than they use to. This has been the case since the summer so I know it's not atmospheric.
Don't get me started on their playlist though. Every since Cumulus has basically treated this station like a back burner station, it really has lost it's luster. I believe Don Scott is the only live DJ on the radio station. Sad Sad...
