This is also known by some as the '''''"Rounding Rule"'''''. | ||
Distances are measured to the nearest kilometer. For example, if the required distance is 67 kilometers and the actual distance is 66.499 kilometers, that rounds down to 66 kilometers and thus, the station would be short-spaced. However, if the actual distance is 66.500 kilometers, that rounds up to 67 and would meet distance separation requirements. | Distances are measured to the nearest kilometer.

This distance | This distance rounding rule shows the most benefit for LPFM stations that are currently short-spaced to another facility because of a subsequent application the other facility filed. In some cases, it would allow LPFM stations to move up to nearly one kilometer closer to the short-spacecd FM facility. For example, the short-spaced LPFM is currently 28.498 kilometers from a short-spaced FM facility. The LPFM licensee needs to move and the only viable site for the antenna is 27..504 kilometers away. Because 28.498 27.504 round into 28 kilometers and both locations. Because these distances are the same, no new interference will take place. | ||
