In general, no. We do know that stations can be used outside their protected contour, but not on most radios... and most listeners won't do the work to search out fringe signals.Which, I assume, is why the owners of the station carried on those translators have never complained about WCOD, nor has WCOD complained about the translators, correct? The presence of WCOD and the translators on the same frequency has no impact on the bottom line of the operators of either?
So in a practical world, that fringe overlap makes no difference at all.
When I have only seen fringe signals be the subject of protest if a new signal blocks the is when the fringe signal is something unique, like a NPR station where no other affiliate is available. Or perhaps the only station in a format with a passionate following, like AAA. But nobody is going to do that for the major formats that are replicated in every market and area.
