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?
The amateur station must cease operation
The amateur station must cease operation on all frequencies below 30 MHz
The amateur station must cease operation on all frequencies above 30 MHz
The amateur station must avoid transmitting during certain hours on frequencies that cause the interference✓Correct answer
Explanation
Where an amateur signal interferes with domestic broadcast reception on receivers of good engineering design, the rule bars operation on the offending frequencies during set evening hours and an additional Sunday midday period, rather than shutting the station down. The restriction is tied to the frequencies causing the interference, not to a 30 MHz dividing line.
