Risvolto di copertina:
Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. In USA AM broadcasting, presunrise authorization (PSRA) and postsunset authorization (PSSA) are permission from the Federal Communications Commission to (broadcast in AM on mediumwave using a power level higher than what would normally be permitted prior to sunrise/after sunset, or in the latter case, provide Class D stations with service into the evening where they would otherwise be required to sign off. Sunrise and sunset times are provided on the licensee's basic instrument of authorization. The power level for both PSRA and PSSA service cannot exceed 500 watts. Power calculations are based on co-channel stations. At 6:00am local time, stations may power up using the station's daytime antenna (if applicable). Provided the locale participates in daylight saving time, special provisions must be made since the PSRA time is based on local time.
