Not sure why but this is nearly always a strong signal here is the the Great Lakes Region
It hits all of N AM well. Here in Denver, when they were experimenting with DRM, it was the only DRM signal I've ever locked on for a long period of time, about an hour or more without a single dropout. (Of course that shows why it's a poor mode for DX'ers, but that's another topic of discussion - the fact it was good at all is more about the quality of this transmission.)
