Yes, LPFM (Low-Power FM) stations are generally required to inform the FCC if they decide to sign off or cease operations for any extended period, including during hours such as 3 AM to 7 AM. This is to ensure compliance with FCC regulations and to maintain accurate records of station operations and potential silent periods.
Additionally, LPFM stations are part of the Emergency Alert System (EAS), and if they plan to sign off or cease operations for a significant period during which they are unable to receive or relay emergency alerts, they should notify the appropriate authorities and coordinate with local emergency management agencies to ensure public safety.
Short Broadcasting Interruptions: LPFM stations that are not in a time-share situation (co-located with other stations) are not required to notify the FCC if they experience a short interruption in broadcasting. There is no need for notification when the station goes off the air briefly.
Silent Period Notification: FCC notification is required only when the LPFM station plans to go "silent" for an extended period. LPFM stations are typically required to maintain a minimum schedule of 5 hours per day, 6 days per week. Schools licensed for LPFM may have exceptions, such as not being required to broadcast during vacation periods.
EAS Obligations During Silent Periods: When an LPFM station is not on the air, it is relieved of its Emergency Alert System (EAS) obligations. However, the station's EAS decoder must continue to log any received alerts during this time.
It's important for LPFM station operators to be aware of these requirements to ensure compliance with FCC regulations and maintain proper records of station activities, including EAS alerts, during both broadcasting and silent periods.
It's crucial for LPFM station operators to follow FCC rules regarding station sign-offs and EAS notifications to avoid regulatory issues and to ensure that the station remains in compliance with emergency alert broadcasting requirements.
