In South, North, West and CC Philly, plus the city of Camden and its suburbs, WMMR and WRNB are just the opposite of the antenna farm signals, they are extremely strong. Due to the fact they both use Liberty One, if it were not for 103.9, WMMR could, AND WOULD of moved to the antenna farm. As it stands now, if 103.9 interferes with WMMR in any way, they would have to reduce power immediately. You would think GM would buy 103.9 just to shut it down or move it and put WMMR in Rox.
