Why does Talk 960 reduce power at night?
KIXW-AM is required by the FCC to reduce power at sunset in order to protect and reduce interference to other radio stations at night.
FCC rules governing the daytime and nighttime operation of AM radio stations are a consequence of the laws of physics. Because of the way in which the relatively long wavelengths of AM radio signals interact with the ionized layers of the ionosphere miles above the earth’s surface, the propagation of AM radio waves changes drastically from daytime to nighttime. This change in AM radio propagation occurs at sunset due to radical shifts in the ionospheric layers, which persist throughout the night. During daytime hours when ionospheric reflection does not occur to any great degree, AM signals travel principally by conduction over the surface of the earth. This is known as “groundwave” propagation. Useful daytime AM service is generally limited to a radius of no more than about 100 miles, even for the most powerful stations. However, during nighttime hours the AM signals can travel over hundreds of miles by reflection from the ionosphere, a phenomenon called “skywave” propagation. Because of this change in signal propagation from daytime to nighttime, if every AM station kept its daytime operating power at night, massive interference would result.
