If WDDM/WPDI moved to 104.7 before the 104.7 translator launched, the translator wouldn't have seen the light of day. The 104.7 translator went on the air before WPRB downgraded to HD, so it needed something to translate, and WWFM supplied them programming. I'm pretty sure they can make more money translating the Indian format on 104.7 via either the 100.7 translator or WPRB-HD2. As it is, 104.7 is a mess in the highest Indian concentration in NJ. 100.7 might be free to translate WPDI if ESPN takes over 98.7-HD2. Listener complaints will get the FCC's attention, and they can force the 104.7 translator off the air.
I wonder if 104.7 can change to a booster for WPDI. Even if they can't be a booster, they have another source for the same programming, so it can operate as a booster. I'd imagine the interference would be bad because there are no terrain obstructions between Hazlet and New Brunswick to block WPDI's signal. I remember hearing a booster interfere with the main with no terrain obstructions with 94.5 The Vibe in Vegas. The main is 70 miles northeast of Vegas, and its signal is blocked in Vegas by a mountain. 94.5's booster is on that mountain and it provided a good signal in Vegas. Northeast of the booster, there was heavy interference with the booster and the main, but no population in that area.
