Deep Dive: E1B08
The correct answer is D: The amateur station must avoid transmitting during certain hours on frequencies that cause the interference. What limitations may the FCC place on an amateur station if its signal causes interference to domestic broadcast reception, assuming that the receivers involved are of good engineering design is that the amateur station must avoid transmitting during certain hours on frequencies that cause the interference. The FCC may restrict operating times and frequencies. For amateur radio operators, this is important for compliance. Understanding this helps ensure legal operation.
Why Other Answers Are Wrong
Option A: Incorrect. Station doesn't have to cease operation completely - it may be restricted to certain hours/frequencies. Complete cessation isn't the limitation. Option B: Incorrect. Station doesn't have to cease operation on all frequencies below 30 MHz - it may be restricted to certain hours/frequencies. All frequencies below 30 MHz isn't the limitation. Option C: Incorrect. Station doesn't have to cease operation on all frequencies above 30 MHz - it may be restricted to certain hours/frequencies. All frequencies above 30 MHz isn't the limitation.
Exam Tip
FCC limitations for broadcast interference = avoid transmitting during certain hours on frequencies that cause interference. Think 'B'roadcast 'I'nterference = 'B'anned 'I'n certain hours/frequencies. The FCC may restrict operating times and frequencies. Not complete cessation, not all frequencies below/above 30 MHz - just certain hours and frequencies.
Memory Aid
FCC limitations for broadcast interference = avoid transmitting during certain hours on frequencies that cause interference. Think 'B'roadcast 'I'nterference = 'B'anned 'I'n certain times/frequencies. The FCC may restrict operating times and frequencies. Important compliance requirement.
Real-World Example
An amateur station causes interference to domestic broadcast reception: The FCC may require the station to avoid transmitting during certain hours (e.g., prime time) on frequencies that cause the interference. The station doesn't have to shut down completely - it may be restricted to specific times and frequencies. This is the limitation - avoid transmitting during certain hours on frequencies that cause interference.
