I have noticed along I-75 that WIZE booms into places like Troy, and Tipp City, yet seems to have issues with a good signal in closer places like Fairborn, Vandalia, or Huber Heights. This seems to be even more evident during critical hours. Why does the non directional WIZE signal beam to the west, more so than any other direction? I recall noticing this when I worked for Great Trails, many many years ago. Is it something to do with ground conductivity?
