Most AM radio stations are required by the FCC's rules to reduce their power or cease operating at night in order to avoid interference to other AM stations. 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 several 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.
According to FCC regulations Livning Bread Radio is called a "daytime" station.
If AM 1060 Living Bread Radio were to stay on air at night we would interfere with the signal of AM 1060 in Philadelphia PA.

WHY DOESN'T AM 1060 PLAY MUSIC?
Living Bread Radio, AM 1060 is a Catholic Talk Radio station. We would like to play Catholic music to entertain our listeners but today we find ourselves in a crisis of Faith. Many people do not understand the very basic teachings of the Catholic Faith. Our Mission is to educate, enlighten and inspire our listeners. Therefore we feel it would be irresponsible to entertain before we educate.
