This test period helps ensure that the station’s operations do not cause interference to any authorized stations, especially those on third adjacent channels.
In broadcasting, a “contour” refers to a specific geographic area or boundary on a map that represents the coverage area of a radio station’s signal at a particular signal strength level. Contours are typically used to illustrate the extent of signal coverage for regulatory and planning purposes.
