What do the terms PSSA and PSRA mean?

The terms PSSA and PSRA refer to Post-sunset authority and Pre-sunrise authority. In the context of radio operations, these terms relate to the permissions and operational guidelines for broadcasting at times when local sunrise and sunset occur.

Post-sunset authority allows a station to continue broadcasting after sunset, which can be crucial for maintaining service and continuity for listeners during the evening hours. Conversely, Pre-sunrise authority permits broadcasting operations before sunrise, ensuring that listeners have access to programming during the early morning.

These time-related permissions are essential for managing interference and ensuring fair access to the airwaves among stations, especially in cases where multiple stations may operate on the same frequency. Understanding these terms helps operators comply with regulations and optimize their broadcast schedules for their audience.
