Well as we now know, DePetro isn’t going to be heard on WADK’s new 101.1 translator whenever they get it on the air. 😛
WWBB doesn’t really factor into 101.1’s viability. Second-adjacent interference is pretty rare these days. It’s more the co-channel. I would expect that the 101.1 LPFM in PVD and the 101.1 translator in Newport will interact a lot like how 96.5 WIGV-LP in PVD and 96.5 W243AI in Newport interact: there’s a clear area where the two signals beat the hell out of each other, but each covers their primary market just fine.
